AMC MECANOCAUCHO® is officially approved by the NATO under the id number NCAGE 0230 B-compliant supplier. Marine type approval ISO 9001:2000 3 PRESENTATION 35 years of experience endorse us PRESENTATION 2 Since 1969 AMC MECANOCAUCHO® has pioneered the manufacture and design of articles for the reduction of integral vibrations from structures and air-borne noise. We create comprehensive ranges of anti-vibration mounts based on metal rubber and rubber spring for the effective reduction of structure borne noise. We reduce noise thanks to our AKUSTIKABSORBER® noise-absorbing and damping composites. THE SOLUTION AMC Mecanocaucho mounts are the solution for noise and vibration THE SOLUTION Machinery, which, by virtue of its design has reciprocating or rotating parts, creates vibration to some degree through imbalance of the moving parts. This vibration produced by a machine leads to different problems, such as a reduction in the machine’s useful life through part wear, plus the transmission of this vibration to other non-insulated adjacent structures, giving rise to problems of noise and vibration transmission. FFT analysis of orders for a diesel engine For more than 35 years, AMC MECANOCAUCHO® has been developing the “AMC MECANOCAUCHO®” range of rubber-metal anti-vibration supports which can solve problems like the ones described above in all types of machinery, mobile or static, thus protecting people and the environment from the harmful effects of noise and vibrations. 3D graphic of the vertical acceleration of a radiator 4 APPLICATIONS APPLICATIONS Applications Our products are used in sectors such as: • Generation of electrical energy • Air compression • Pumping of liquids • Industrial vehicles • Machine Tools • Marine propulsion and auxiliary equipment • Agricultural and construction equipment machinery • Acoustic isolation of premises and sites • Vibrating screens, Hoppers, Silos, Feeder screens 5 AMC ENGINEERING SERVICES 1 Calculation AMC MECANOCAUCHO ® calculates anti-vibration solutions by taking into account data such as weight, mount positions, type of machine, C of G, frequency of excitation, etc...

The frequency of the mass spring system is equal to: The damping parameters are: Where Cc is the critical damping and the damping coefficient. For this system we obtain a transmissibility T and an figure 3 magnification factor A: K = N/m M= in Kg Fo in Hz C in Ns/m The effectiveness of the suspension may be measured by transmissibility, i.e. by the force which is transmitted by the machine to the ground or floor. It is defined as the ratio between the force transmitted to the ground, FOT, For the case of active and and the original force produced by the vibration FO. Another practical term is often used to describe the passive isolations, we will have to efficacy of an anti-vibration mount, namely the degree of insulation, which is: Figure 5 represents the transmissibility curve of the schematic mass spring system of figure 3. Transmissibility equation: Taking the following parameters into account: Excitation Response figure 5 Own Pulsation: for Examining this curve allows us to reach basic conclusions for an effective isolation. 10 ANTI-VIBRATION TECHNIQUES times less the natural mount. It is a crucial parameter that must be addressed frequency, transmissibility is greater than one, then the when designing anti-vibration suspensions. If the frequency of excitation is force transmitted is greater than the excitation force, there is magnification of the vibrations. When we work in this area, the existing damping in the system is important. The CREEPING greater the latter, the smaller the magnification of the If an elastomeric element is under a static load, this load vibrations will be. produces a progressive increase in deformation. AND LONG-TERM B E H AV I O U R This phenomenon may be important in a wide variety of If the frequency of excitation is times greater than the natural frequency, transmissibility is less than one, or applications, from mounts for buildings to engine mounts. Creeping at a given time t is calculated as: in other words the force transmitted is less than the force originated in the system, then we are in the damping area. In order to achieve the greatest isolation, the lowest possible natural frequencies should be sought. There are two ways of doing this: And is expressed as a percentage (%) of the initial • By increasing the system mass. • B y r e d u c i n g t h e s t i ff n e s s o f t h e deformation. This value depends on the geometry of the mount, and above all on the way the rubber is worked. anti-vibration mount. To increase the efficacy of the isolation in the damping area, it is advisable to have low damping, although weak damping generates greater displacement when passing through the resonance, it is advisable to use a damping coefficient t so that passage through the resonance does not give rise to inadmissible displacement for the machine. STATIC AND DYNAMIC STIFFNESS The stiffness of a rubber anti-vibration mount changes when a dynamic force is applied to it. This parameter depends on architecture, the compound used and even the frequency of excitation. Generally speaking, dynamic stiffness is always greater than static stiffness, so calculations based on static stiffness may lead to wrong conclusions. In some cases it is possible to reach limits of dynamic stiffness which are two and even three times greater than the static stiffnesses. DAMPING Designs that use rubber in shear are more conducive to The damping coefficient depends basically on the “Creep” than designs which use rubber in compression compound used in manufacturing of the anti-vibration or shear and compression. 11 ANTI-VIBRATION TECHNIQUES DYNAMIC TESTING MACHINE Dynamic stiffness can only be established by measurement on a dynamic test bench. Similarly, the damping coefficients of compounds are further values that can be measured with this type of machines. One concept that must be taken into account when designing an anti-vibration mount is its durability. A dynamic testing machine allows us to conduct fatigue tests that reproduce the real working conditions of the part so that its useful life can thus be predicted accurately. 2-ANALYSIS OF SYSTEMS OF MORE THAT ONE DEGREE OF FREEDOM In actual fact, there are cases where the model of 1 degree of freedom cannot correctly define the behaviour of the ® equipment to be isolated. In such cases AMC MECANOCAUCHO have analysis tools that enable more elaborate models to be made taking into account the 6 Degrees of Freedom rules. The latest computing tools can also generate virtual models of solid rigid multiples and study how they interact with each other and with the environment. As a result, we can ascertain the natural frequencies of the system which are really important to prevent them from coinciding with the excitation frequencies so as not to have resonance problems. 12 GENERAL CHARACTERISTICS OF ELASTOMERS NATURAL RUBBER Natural rubber natural is used in the manufacture of elastomers with high elasticity and tear strength. It is a strong material with excellent abrasion resistance. Of all the rubber families, natural rubber offers the best resistance to mechanical and dynamic SYNTHETIC RUBBERS Synthetic rubbers are conceived using raw materials such as petroleum or natural gas. At the moment they have found their own fields of application where natural rubber does not meet the required technical specifications, such as heat resistance loads. Natural rubber is not stable versus non-polar liquids such as mineral oils, lubricants, fuels and aliphatic and aromatic and hydrocarbons and chlorides. Its moderate ozone stability can be improved with additives. (silicones and EPDM), oils (nitrils) or weather (neoprene). MIXTURES An elastomer is not composed of a single material, but rather cont ains ver y varied subst ances. Mixes can be made with different formulations to obtain different stabilities and different mechanical characteristics. HARDNESS The hardness of the elastomer depends on its formulation and is measured by means of practical units established by different standards such as shöre (A) or IRH. AMC Mecanocaucho uses the shöre scale (A), and manufactures anti-vibration mounts THERMAL STABILITY Natural rubber based vulcanised materials are stable within the limits of – 40ºC to + 80ºC, if the action of the temperature in question is permanent. with hardnesses of between 40 and 75 shöre. If the temperature acts sporadically, these elastomers can act from – 50ºC to + 120ºC, although these limits may be varied by using specific formulations. OZONE RESISTANCE This characteristic is important for measuring an elastomer’s weather stability. The speed at which is may deteriorate depends on the prevailing environment conditions and the formulation of the compound. ADHESION The bond between elastomers and metals is made by adhesives which are applied to the metal parts which leverage the process of vulcanisation to create a firm bond bet ween elastomer and met al. CREEPING AND PERMANENT DEFORMATION The creeping and permanent deformation of elastomers subjected to continuous stress is unavoidable. The material presents a creep which in the case of permanent deformation is expressed as a percentage of the static load, values of 25% are usual in anti-vibration mounts. TOLERANCES No part can be manufactured with absolute precision, the dimensional tolerances of rubber articles are established in the ISO 3302 standard. As for physical properties, hardness may vary by ± 5 shöre, and stiffness “K” admits a margin of ± 20%. In cases of highly demanding requirements, this margin can be reduced to ± 10% thanks to a highly-sophisticated process. 13 mm.

Their tall height profiles produce large deflections, low natural frequencies, and excellent vibration isolation results. This range of mounts is suitable for applications where high vibration isolation in the 85-95% range is a priority. TECHNICAL CHARACTERISTICS -The top metal hood protects the rubber from the Ozone, UV rays, diesel or oils which damage the rubber. -The metal parts have a suitable anticorrosive treatment for outdoor applications. -They have an interlocking metal component that provides a fail-safe protection for mobile applications. This device limits the ascending vertical movement when the mounting is submitted to shocks at traction. -The mounts are clearly identified, as the bases are engraved with the type and hardness, which makes it possible to easily recognise the piece even after several years of use. -The hood has a cross stamped on the top, which enhances its rigidity on mobile applications and also improves the evacuation of oils or liquids that precipitate onto it. APPLICATIONS This mount is suitable for the isolation of mobile rotating machines which are exposed to axial and radial shocks, dripping, oil diesel or exposure to the weather. It is particularly interesting for applications where a high level of vibration isolation is required.

Their special design offers different stiffnesses on the three axes, they are antivibration mounts with great vertical elasticity, great longitudinal stiffness and optimal lateral stiffness to offer extra isolation on this axis. TECHNICAL CHARACTERISTICS -The top part of the hood has a cross-shaped stamp, which improves its stiffness in mobile applications and also improves the evacuation of oils or liquid which splash onto it. -The metal parts have an anticorrosive treatment which is suitable for outdoor applications. Marine Certificate -The mounts are clearly identified, as the bases are engraved with the type and hardness. 1 2,5 -They have an interlocking metal component that provides a fail-safe protection for mobile applications. This device limits the ascending vertical movement when the mounting is submitted to shocks at traction. -The top part protects the elastomer inside from possible dripping oil, diesel, ozone and ultraviolet emissions that may cause major damage to the rubber. 0,75 M B -For marine engine applications, contact the AMCMecanocaucho® technical department. APPLICATIONS C F D 20 G A J The different stiffnesses for each axis make it possible to offer major flexibility in the direction perpendicular to the crankshaft/shaft of the motor. This provides more effective isolation from vibrations of all types of engines In mobile rotating machines that need a major isolation capacity from vibrations and noises, such as: - Pumps - Marine-Land units - Mobile electrical panels - Industrial vehicles - Compressors - Ventilators - Marine Propellers * In order to adapt its products to the state of the art, AMC S.A. reserves the right to modify the conception and manufacture of the materials presented in this catalogue without prior notice MARINE MOUNT MARINE TYPE MOUNT TYPE A SMALL B C D 120 38.5 60 F G J M 100 11 14 11 M-12 AMC Code 35 Sh Ref * 183 LARGE 50 228 75 68 140 13 30 112 182 18 20 M-16 34 26 M-20 Code 45 Sh Code 55 Sh Code 65 Sh Code Weight 75 Sh (g) 136001 136002 136003 136004 Load (kg) MEDIUM Code 40 Sh 35 Ref 136021 Load (kg) 95 Ref * * 45 70 Load (kg) 397 95 136022 136023 136024 136025 110 * * 139 200 857 350 136041 136042 136043 136044 350 490 700 2250 1080 * In the manufacturing process DYNAMIC MARINE MOUNT MARINE MOUNT DEFLECTION AMC NATURAL FREQUENCIES MECANOCAUCHO® DYNAMIC MARINE MOUNT AMC LOAD DEFLECTION GRAPHS MECANOCAUCHO® MARINE TYPE MOUNT Big M ari ne D7 5 1000 Big M ari ne 800 700 800 700 C6 5 600 600 400 Big M ari ne A4 5 M ed ium 250 M ed ium Load (Kg) Carga (Kg) 200 150 M ed ium 100 80 M ed ium 70 5 B5 ne ari 5 E7 ig M B ne ari M m 5 u i A4 ed ne M ari M Big 500 M ed ium B5 5 400 M ari ne E7 5 300 250 M ari ne D6 5 200 M ari ne C5 5 M ari ne B4 5 Sm all M ari ne M ari ne A3 5 Sm all M ari ne 60 ium ed M 150 Load Carga(Kg) (Kg) Big M ari ne 500 300 5 D7 ne ari M Big 5 C6 ne ari M Big 1000 ium ed M 70 60 C5 5 5 C5 ne ari M 5 B4 ne ari M 5 D6 ium 5 ed ne A3 M ari ne ll M ari a M Sm ium 55 ed eC n M i ar M all Sm 100 80 D6 5 5 D6 ne ari M 50 50 Sm all M ari ne 40 Sm all M ari ne 30 25 5 B4 ne ari M all 0 Sm A4 ne ari M all Sm 40 B4 5 30 A4 0 25 20 20 15 15 10 10 7 8 9 10 11 12 13 Natural Frequency frecuencia propiaHzHz 14 16 18 20 1 1,5 2 3 4 5 6 Deflection (mm) Flecha (mm) * In order to adapt its products to the state of the art, AMC S.A. reserves the right to modify the conception and manufacture of the materials presented in this catalogue without prior notice 21 CONES DESCRIPTION The AMC-Mecanocaucho® cones work the rubber in shear compression. They are composed of two parallel conical metal parts. They have two washers, one as a buffer and the other for centering. TECHNICAL CHARACTERISTICS The Mecanocaucho ® Cone supports are safe and stable elements, since they do not allow the suspended elements to tilt, and are also flexible enough to avoid the transmission of noise and vibration through the structure. They are supplied with stop and centering washers. This renders deflection above the limits of the Mecanocaucho® Cones impossible, even at extreme loads. The washers protect the natural rubber (which is highly elastic and highly resistant) from ozone and aging, as well as from metal knocks and dripping oil. The characteristic deflection curves of the Mecanocaucho® Cone mounts with centering washer are quite linear, increasing progressively as the load increases. Thanks to this they can safely dampen overloads of up to three times the maximum admissible load. APPLICATIONS The Mecanocaucho® Cone mounts have been designed specially for use in engines and auxiliary machinery for static applications and for applications in all kinds of vehicles.

Diesel engines require MD mounts, particularly when they have few large-diameter cylinders, which makes the engine create high-amplitude vibrations, therefore requiring extra damping to correct these high amplitudes. 238 238 76 238 47 2,5 34 Ø 9,5 M 12 B B 26 * In order to adapt its products to the state of the art, AMC S.A. reserves the right to modify the conception and manufacture of the materials presented in this catalogue without prior notice Ø 64 93 MD TYPE Vibration level measured engine Nivel vibratorio medido in enthe el motor [m/s] Autospectrum(Input1) FRF : Input : Input : FFT Analyzer 20m 18m 16m 14m 12m 10m 8m 6m Natural mount Soporterubber caucho natural MD mountMD Soporte 4m 2m 0 0 100 200 300 400 [Hz] 500 600 700 800 m K1 K1= Main stiffness - K2= Secondary stiffness C= Damping coefficient - m= Mass K2 C It is a very suitable mount for engines where it is not physically possible to install the antivibration mounts at the same height as the crankshaft. * In order to adapt its products to the state of the art, AMC S.A. reserves the right to modify the conception and manufacture of the materials presented in this catalogue without prior notice 27 cones 100 DESCRIPTION: The AMC-Mecanocaucho ® mount cone 100 works the elastomer at shear compression. It is comprised of a highstrength external metal armour and a conical internal armour which includes a leveller to align the suspended unit. TECHNICAL CHARACTERISTICS: The AMC-Mecanocaucho® mount CONE 100 is conceived to offer predominant axial elasticity under heavy loads. The used elastomer is a low dynamic rigidification elastomer, which makes it possible to obtain low natural frequencies thus maintaining excellent stability of the suspended unit. The mount’s radial stiffness is superior to the axial. This is particularly interesting for applications where great horizontal stability needs to be maintained. 95 20 10 80 10 Max Maxaltura heigth level 10 Nivel. M 24 15 The AMC-Mecanocaucho ® mount is supplied with a leveller. This makes it possible to easily align transmission shafts without having to use additional accessories to do so. 150 Ø1 The standard model also features a traction-based antibreakage system. Thanks to this, and to the ruggedness of the metal parts, this mount is suitable for applications where the suspended unit is submitted to great shocks.

TECHNICAL CHARACTERISTICS: The V-shaped generator mounts render it possible to make installations which are more elastic than the ones usually made with cylindrical or bobbing mounts. This makes it possible to achieve lower frequency and consequently better vibration isolation. Stability is enhanced when two are installed, symmetrically opposed. See fig. 1. They have two different length screws which facilitate the assembly of the the engine to the chassis. The screws can be supplied in different lengths to order. Q P They have two “anti-turn” tabs which stop the mount from turning when strong tightening torque is applied (very frequently) with pneumatic tools. N They are supplied in 2 hardnesses to adapt to different load ranges. J They provide vibration attenuation of above 90% in diesel or petrol single-cylinder engines running at 3000 rpm.

It is very suitable in the elastic suspensions of machines that present vibrations of horizontal components. It is comprised of flat metal parts. The top metal part is circular and has a passing screw hole or nut for screwing or securing to the machine or frame. The lower metal part is elliptic with two lugs in which the drill holes for securing the unit to the ground are located. The two parallel metal parts are joined to each other by a rubber part bonded to them, shaped like a dome. OPERATION AND ASSEMBLY The rubber works on the basis of compression. In the event of shocks or accidental overloads, the inside and outside profiles of the rubber act as a progressive stop by coming into contact with the top and bottom flat support surfaces. During assembly, a circular plate or hood must be placed on the top armature to work as a progressive stop in overloads. For the assembly of the D.S.D. mount with lugs on metal frames, screw it into the fixation holes. To secure it to concrete prepare claws with threaded rod at the distance between the centres of the drill holes of the lower armature. For applications where high vibration isolation is needed, the DRD mounts should be referred to. TECHNICAL CHARACTERISTICS The D.S.D. mount offers transversal elasticity which is very equivalent to its axial elasticity. It is therefore efficacious against all vibrations from any direction. ADVANTAGES • The direct placement of the machine with its mounts on the floor or ground, with the possibility of suppressing the need for any fixation. • Speed of placement of the mount and easy movement of the machine to the required spot. • Economical. • Efficacious: three ‘’standard’’ varieties marked on each part (Soft: hardness A 45, Medium: hardness B 60, Hard: hardness C 75), enabling the user to choose the most suitable mount for the load to be supported and the vibration frequency. • The possibility of doubling its elasticity by placing two D.S.D. mounts serially for each support point. APPLICATIONS The D.S.D. elastic mounts are assembled preferably on rotating machines without major dynamic disequilibriums, where vertical and transversal elasticity is convenient. They are therefore very interesting in ventilators, rotating pumps, torque or frequency converters, electrical engines, mecanographic machines, etc. ASSEMBLIES 38 * In order to adapt its products to the state of the art, AMC S.A. reserves the right to modify the conception and manufacture of the materials presented in this catalogue without prior notice DSD DSD TYPE Type A B C D E F G H AMC Code 45 Sh DSD 40 40 20 M-6 19 29 52 64 8,5 Ref 134001 DSD 60 60 24 M-6 14 34 76 90 8.5 DSD 80 80 DSD 100 27 100 DSD 150 28 150 DSD 200 M-8 M-10 39 200 25 22 M-14 44 65 70 34 M-18 115 35 140 100 124 182 240 120 148 10 214 12 280 14.5 Code Weight 60 Sh 75 Sh (g) 134002 134003 27 78 Load (kg) 4 10 Ref 134004 134005 134006 Load (kg) 15 25 45 Ref 134007 134008 134009 Load (kg) 75 110 150 Ref 134010 134011 134012 Load (kg) 90 160 220 Ref 134013 134014 134015 Load (kg) 130 250 350 Ref 134016 134017 134018 Load (kg) 500 825 1250 DYNAMIC DSD DEFLECTION DSD AMC NATURAL FREQUENCIES MECANOCAUCHO® DSD TYPE AMC LOAD DEFLECTION GRAPHS MECANOCAUCHO® DSD TYPE 1500 146 274 703 1758 1500 DS D 1000 DS D 500 400 20 04 5 20 07 5 DS D 200 150 DS D 400 15 07 5 DS 15 D 8 06 07 5 0 15 0 4 DS D 5 80 DS 60 D 10 DS 04 D 5 80 45 80 70 60 50 45 00 D2 S D 75 50 D1 S D 75 00 D1 60 DS 5 50 0 7 SD 1 8 D SD 60 D 45 00 1 50 D D1 DS S D 0 45 06 8 0 0 5 D 04 DS D1 DS D8 DS 500 DS D 100 60 00 D2 S D 800 700 600 20 06 0 300 250 75 00 D2 S D 1000 DS D 300 250 10 07 5 DS D 200 150 10 06 0 DS D 40 30 DS D 25 20 DS D 15 100 Load Carga(Kg) (Kg) DS D 800 700 600 Load Carga(Kg) (Kg) 8.2 Code 60 75 80 70 60 50 5 07 D6 S D 40 30 0 06 D6 DS 25 60 60 20 15 60 40 DS D 10 10 0 D4 DS 40 60 5 04 D6 DS 60 5 5 DS D 3 4 5 6 8 10 12 Natural Frequency frecuencia propia Hz 40 45 14 5 04 D4 S D 3 16 18 20 22 1 1,5 2 3 4 5 6 7 Deflection (mm) * In order to adapt its products to the state of the art, AMC S.A. reserves the right to modify the conception and manufacture of the materials presented in this catalogue without prior notice 39 ATP DESCRIPTION The A.T.P. mount is an elastic mount conceived to provide antivibration isolation for medium and high frequencies in any kind of machines (gen sets, motor pumps, motor compressors, hydraulic units, etc.) -The top part has a hood-shaped armature to protect the rubber from oil, grease, petrol, diesel, dust, etc. OPERATION AND ASSEMBLY The rubber on the A.T.P. mount works at shear, ending in the form of a progressive stop which makes it possible to limit the elastic end of stroke at shear, in the event of impacts or transient overloads, as occurs in the case of apparatuses on vehicles. Thus, as of the deflection indicated in the catalogue it presents a gradually decreasing flexibility with load. This offers optimal conditions to solve an aperiodic suspension. The A.T.P. mounts may be secured to the floor or ground threaded rod claws which are inserted into the concrete. The can also be screwed in between the base of the machine and the metal chassis. TECHNICAL CHARACTERISTICS The elastomer used is a compound based on natural rubber specially studied to obtain good aging at alternate deformations. The load capacity is given in the catalogue for the maximum static load admitted, and can withstand strong overloads. The flexibility in an A.T.P. mount is approximately 4 times more rigid in the radial direction than in the axial direction. ADVANTAGES Figure 1 Figure 2 • Direct placement of the machine on the floor or ground, as required. • Quick placement of the elastic mounts. • Protection of the rubber from aggressive agents. • Fixing by bolts or screws. • Efficacy: three varieties of hardness are manufactured (Soft: hardness A 45, Medium: hardness B 60, Hard: hardness C 75). This enables the user to choose each mount depending on the load to be supported and the frequency of the vibrations to be eliminated. APPLICATIONS In all assemblies where “pitching” of the unit suspended needs to be avoided, as well as the protection of the rubber and the possibility of supporting overloads. • Medium and high frequency motor compressor units. • Gen sets. • Hydraulic Units. • Marine auxiliary units. • Ventilators, etc. 40 * In order to adapt its products to the state of the art, AMC S.A. reserves the right to modify the conception and manufacture of the materials presented in this catalogue without prior notice ATP ATP TYPE Type ATP 020 ATP 120 ATP 220 ATP 420 A B 50 B1 30 74 - 42 92 53 53 124 C 63 75 94 D M-8 E 50 M-10 7 72 M-12 9 90 M-16 11 114 13 F 67 90 114 144 G AMC Code Code Code Weight 45 Sh 60 Sh 75 Sh (g) Ref 133101 133102 133103 143 Load (kg) 50 75 100 Ref 133104 133105 133106 Load (kg) 70 120 175 Ref 133107 133108 133109 Load (kg) 140 200 300 Ref 133110 133111 133112 Load (kg) 300 500 800 16 32 36 60 DYNAMIC ATP DEFLECTION ATP AMC NATURAL FREQUENCIES MECANOCAUCHO® ATP TYPE AMC LOAD DEFLECTION GRAPHS MECANOCAUCHO® ATP TYPE 379 618 1510 1000 1000 800 P AT 700 800 5 07 42 600 6705 20 P4 T A 700 600 500 P AT 500 0 06 42 400 60 20 P4 AT 400 300 P AT P AT 300 5 07 22 5 04 42 250 45 20 P4 T A 75 20 P2 AT 250 200 5 04 22 P AT 5 07 02 80 P AT 60 50 60 20 P2 T A 45 20 P2 AT 60 20 P1 T A 5 07 02 60 20 P0 AT 70 0 06 02 5 04 12 60 100 80 P AT P AT 70 75 20 P1 T A 150 Load Carga(Kg) (Kg) P AT Load Carga(Kg) (Kg) 5 07 12 0 60 0 6 20 22 P 1 AT 150 100 P AT P AT 200 45 20 P1 AT 50 P AT 5 04 02 40 45 20 P0 AT 40 30 30 25 25 20 20 15 15 10 10 1 6 8 10 12 14 Natural Frequency Hz frecuencia propia Hz 16 20 1,5 2 3 4 5 6 Deflection (mm) Flecha (mm) * In order to adapt its products to the state of the art, AMC S.A. reserves the right to modify the conception and manufacture of the materials presented in this catalogue without prior notice 41 AT DESCRIPTION The “A.T.” mount is specially designed to provide isolation for medium and high frequencies. The rubber is bonded to two concentric tubular metal parts. The inside metal part is a cylindrical tube. The outside metal part is also tubular, with a flange where the fixing drill holes can be made. OPERATION AND ASSEMBLY In view of the “A.T.” s special structure, a metal washer should be used at the top and the bottom of the mount, making the rubber work at shear, with the action of a progressive stop as the washer crushes the top of the mount in the case of overload. Therefore, as of a certain ‘’deflection’’ the “A.T.” mount presents a flexibility which gradually decreases with loads. This offers optimal conditions to solve an aperiodic suspension. The assembly is very safe, since the main fixing bolt to the machine cannot be released even in the event of deterioration of the “A.T.”, since the cap at the top and the lower washer which holds the bolt prevents this. TECHNICAL CHARACTERISTICS The “A.T.” mount has a radial elasticity (in all directions perpendicular to its axis) in the order of 1/4 of its axial elasticity. It is manufactured in three hardnesses to facilitate the choice of the most suitable mount (Soft: hardness A 45, Medium-sized: hardness B 60 and Hard: hardness C 75). ADVANTAGES • Ruggedness: the “A.T.” mounts may be used on mobile machines, which would not be possible in the case of simple support parts. • No time wasted. • Simple assembly which is adapted to a wide number of cases due to its different possibilities (mural, on chassis, on concrete, serially, etc.). APPLICATIONS The “A.T.” elastic mounts can be used to great advantage for the vibration isolation of engines, piston compressors, presses, electric transformers, mobile units, machines, on concrete buttresses, etc. AT DEFLECTION AT DEFLECTION AMC LOAD DEFLECTION GRAPHS MECANOCAUCHO® AT TYPE AMC LOAD DEFLECTION GRAPHS MECANOCAUCHO® AT TYPE 300 3000 75 21 AT 250 200 75 20 AT 150 75 11 AT 100 75 02 AT 60 75 01 T 02 A AT 60 01 AT 80 70 60 50 75 81 AT 75 0 8 AT 2500 60 21 AT 60 60 20 11 AT AT 2000 45 21 AT 1500 75 71 AT 5 60 0 4 45 10 AT 2 11 AT AT 5 4 02 5 AT 04 45 AT 1 01 AT 800 75 51 AT 700 75 00 AT 500 400 25 60 00 AT Load (Kg) Carga (Kg) Carga (Kg) Load (Kg) 75 50 AT 45 00 AT 15 75 31 AT 75 30 AT 300 60 75 50 41 AT AT 75 60 40 31 AT AT 8 AT 60 30 AT 5 5 04 00 AT R 70 AT 45 45 40 AT 45 30 AT 150 0 06 00 AT 45 80 AT 5 45 1 4 31 T 4 AT A 250 200 45 81 AT 45 71 AT 45 70 60 AT 45 51 AT 60 1 4 45 AT T 50 0 A 06 4 AT 10 5 07 00 R 70 AT 60 51 AT 600 20 60 71 AT 60 75 T 70 0R A 7 AT 75 70 AT 1000 40 30 60 81 AT 0 06 8 AT 1800 100 80 70 60 50 2 40 30 1 25 0,5 1 1,5 2 Deflection Flecha (mm) (mm) 42 3 4 5 6 1 1,5 2 3 4 5 6 8 Deflection Flecha (mm) (mm) * In order to adapt its products to the state of the art, AMC S.A. reserves the right to modify the conception and manufacture of the materials presented in this catalogue without prior notice 10 12 at AT TYPE Type A B C D E F G H I AT 000 25 11 3 7 6,2 20 4 19 3,2 3 AT 00 36 28 12,5 11,5 8,1 26 12 26 5,2 3 AT 01 48 40 18 18 12,1 37,5 8 - - 1 AT 02 48 51 24 18 12,1 37,5 8 - - 1 AT 10 60 47 20 18 12,2 49 8 69 8,2 73 4 AT 11 60 60 31 18 12,2 49 8 69 8,2 73 4 AT 20 70 55 27 19 18,2 55,7 10 - - AT 21 round 70 70 39 19 18,2 55,7 10 80 8,5 AT 21 lugs J Fig. 1 86 1-4 86 1-4 AT 30 90 75 29 28 20,2 65 16 78 8,5 2 AT 31 round 90 95 47 28 20,2 65 16 95 8,5 1-4 AT 31 lugs 1-4 AT 40 100 90 42 28 22,2 74 18 100 8,5 112 1-4 AT 41 100 110 49 28 22,2 74 18 100 8,5 112 1-4 AT 50 120 100 47 33 40,2 86 20 114 8,5 4 AT 51 120 120 63 53 40,2 86 20 104 10,5 2 AT 70 round 165 98 36 46 60,2 118 22 145 10,5 2 AT 70 165 140 66 46 60,2 118 22 145 10,5 2 AT 71 165 170 96 46 60,2 118 22 145 10,5 2 AT 80 230 167 95 53 80 170 30 204 12,2 2 AT 81 230 185 113 53 80 170 30 204 12,2 2 Figure 2 Figure 1 G I H Figure 3 AMC 45 Sh Ref Load (kg) Ref Load (kg) Ref Load (kg) Ref Load (kg) Ref Load (kg) Ref Load (kg) Ref Load (kg) Ref Load (kg) Ref Load (kg) Ref Load (kg) Ref Load (kg) Ref Load (kg) Ref Load (kg) Ref Load (kg) Ref Load (kg) Ref Load (kg) Ref Load (kg) Ref Load (kg) Ref Load (kg) Ref Load (kg) Ref Load (kg) Code Code Code Weight 60 Sh 75 S (gr) (g) 132171 132172 132173 6 8 10 132101 132102 132103 39 20 30 40 50 132104 65 132175 70 132107 85 132110 100 132113 135 132116 65 132105 85 132176 100 132108 120 132111 150 132114 190 132117 80 132106 110 132177 120 132109 150 132112 180 132115 250 132118 144 250 344 437 437 132119 132131 132132 175 240 300 132133 132134 132135 250 350 420 132136 132137 132138 522 132139 139140 132141 225 320 380 132145 132146 132147 250 360 480 789 775 895 1305 325 440 550 1494 400 550 670 132162 132163 132164 3124 450 600 800 132165 132166 132167 3124 700 900 1100 132168 132169 132170 3790 850 1100 1400 7096 1250 1800 2300 7702 1600 2100 2600 Figure 4 I G H G I G H A J A D D B B C C E F E F * In order to adapt its products to the state of the art, AMC S.A. reserves the right to modify the conception and manufacture of the materials presented in this catalogue without prior notice 43 SCB The SCB elastic mounts are elements that work on the basis of compression since thanks to their design and assembly they provide an anti-rebound effect, thus permitting safety assemblies.

Two elastic elastomer parts located in the inside are sandwiched between the two metal parts. TECHNICAL CHARACTERISTICS As it is not bonded, this mount can dampen impacts caused by the friction of the elastomer with the metal parts. On the other hand, it is not the best mount to insulate low and medium frequencies. It can work axially, upwards and downwards. Radially at 360°. The elastomer may be chosen for the functions in which it is to be used, such as high temperatures, steeped in oil, outdoor, etc. APPLICATIONS Having a captive elastomer affords total safety, particularly in assemblies on vehicles. They are small for the loads to be supported. It can be manufactured in stainless steel for the food industry and in different elastomers as per needs, as already indicated. Very useful in machines on vehicles by virtue of their utterly safe assembly, as well as cold units on buses. Also in compressors, transformers, frequency variators, etc., on trains or other transport elements. 48 * In order to adapt its products to the state of the art, AMC S.A. reserves the right to modify the conception and manufacture of the materials presented in this catalogue without prior notice SPS SPS TYPE Type A SPS 020 B 50 C 28 D M-8 50 E 6 F 60 AMC Ref 76 38 M-10 63.5 6.7 76 Ref Code Weight 45 Sh 60 Sh 75 Sh (g) 80 100 180 240 171 150 140002 140004 140006 Load (kg) 524 300 DYNAMIC SPS SPS DEFLECTION AMC NATURAL FREQUENCIES MECANOCAUCHO® SPS TYPE AMC LOAD DEFLECTION GRAPHS MECANOCAUCHO® SPS TYPE SP S 300 200 SP S 150 12 06 0 SP S SP S SP S 80 70 75 20 S1 SP 250 60 20 S1 SP 200 12 04 5 100 300 12 07 5 02 06 0 02 04 5 100 60 20 S0 SP 80 70 60 60 50 50 40 40 30 45 20 S1 SP 75 20 S0 SP 150 02 07 5 Load (Kg)(Kg) Carga SP S 250 Load Carga(Kg) (Kg) Code 140001 140003 140005 Load (kg) SPS 120 Code 45 20 S0 SP 30 10 15 20 Natural Frequency frecuencia propiaHz Hz 25 30 1 1,5 2 3 4 Deflection (mm) Flecha (mm) * In order to adapt its products to the state of the art, AMC S.A. reserves the right to modify the conception and manufacture of the materials presented in this catalogue without prior notice 49 MOUNTS FOR LARGE LOADS AMC Mecanocaucho® Anti-skid AMC Mecanocaucho® Type B CODE CODE 141003 141004 AMC Mecanocaucho® Type P Anti-skid AMC Mecanocaucho® Type P CODE CODE 141005 141006 77 8 93 8 35,1 50 AMC Mecanocaucho® Type G.C.

The most classic use is for damping high frequency vibrations without the need for any anchoring. The user cuts them to the relevant size and can apply them using an adhesive, or simply by placing them on the base of the machine. In cases where contact with oils is foreseen, this should be indicated on the order. The mat will be more or less elastic or anti-skid, depending on the different models.

AMC MECANOCAUCHO® BUFFERS DESCRIPTION The rigid buffers used as ends of stroke or to check moving parts give rise to very high stresses at the time of the impact and therefore to rapid deterioration, accompanied by an often unacceptable noise, particularly when these impacts are repeated periodically. The elastic buffers get rid of these drawbacks completely, as they are soundproofed with rubber. The single buffer is a flat surface of rubber and therefore responds immediately to impact, without over-extending the stroke of the moving organ. The progressive buffer has a conical form in the rubber, and therefore makes contact on a progressive surface, which increases with crushing. The action is more gradual and is particularly good for a considerable absorption of energy, without a prohibitive instant stress. OPERATION AND ASSEMBLY The elastic buffers can be used in these two possibilities: • AS ACTUAL BUFFERS: The impact takes place as an end of stroke, taking into account the maximum deflection the stop may give. • AS ELASTIC MOUNTS. When installed as elastic mounts, the buffers may be screwed to the base of the machine so that its flat surface rests directly on the floor or ground. TECHNICAL CHARACTERISTICS The elastic buffers are made with a compound of rubber which permits major deformations with notable absorptions of energy. They can be made with high-damping rubber to order. The absorption of energy is performed thus, irreversibly and opposes the rebound phenomenon. ADVANTAGES • Easy to install in all cases. • Great efficacy when used as mount or as buffer. • Possibility of moving the machines, which are not secured to the floor or ground, or of moving the buffers to different points where ends of stroke may be made. APPLICATIONS AS BUFFERS: In any case for limiting a flexible element. • End of stroke of spring or damper. • End of stroke of cranes and hoists. • Setting of fragile material in packings. * In order to adapt its products to the state of the art, AMC S.A. reserves the right to modify the conception and manufacture of the materials presented in this catalogue without prior notice 59 SIMPLE BUFFERS AMC MECANOCAUCHO® TYPE A APPLICATIONS A AS BUFFERS: In any case for limiting a flexible element. • End of stroke of spring or damper. • End of stroke of cranes and hoists. • Setting of fragile material in packings.

They can be used in a wide variety of applications, particularly for elastic suspensions and antivibration isolation of machines and different mechanical organs. They are made of a block of rubber with two parallel metal parts at the end which enable it to be fixed either by screws in the ‘’C’’ model or with nuts in the ‘’A” model or a combination of both in the ‘’B” model. The rubber block may be cylindrical in cases requiring greater load capacity or as a diabolo when greater elasticity is required in all directions. OPERATION AND ASSEMBLY Its elasticity is much greater in all the directions parallel to the armatures than in the perpendicular direction. The rubber works based on compression or shear depending on the direction it is placed at installation time. This direction is made according to the use and the objective. It is therefore installed with nuts or screws depending on the model chosen, with one part attached to the fixed chassis and the other to the machine to be suspended. TECHNICAL CHARACTERISTICS Depending on the size of the rubber block, the AMC Mecanocaucho® bobbing has more or less elasticity, which is greater particularly in all directions perpendicular to its axis (shear). The AMC Mecanocaucho® bobbing thus makes it possible to make joins which permit major relative movements, up to several millimetres (in the case of heat expansion, chassis deformations, etc.). The AMC Mecanocaucho® bobbing serves very well for the vibration isolation of machines where the vibrations are perpendicular to their axis, unless these stresses are too much when applied in this direction. ADVANTAGES • Easy to install. • High elasticity (particularly transversal). • Economical. APPLICATIONS The AMC Mecanocaucho® bobbings are particularly suitable for installation on small motor-pumps, motor-ventilators, driers, sieves, compactors, washing machines, electrical motors, on-board control panels, measuring apparatuses, control cabinets, microphones, fluorescent tubes, etc. 64 * In order to adapt its products to the state of the art, AMC S.A. reserves the right to modify the conception and manufacture of the materials presented in this catalogue without prior notice MOUNTS AMC MECANOCAUCHO® BOBBINGS TYPE A A B C H 12.5 10 15 20 M -5 10 16 OPERATION AND ASSEMBLY Their elasticity is much greater in all the directions parallel to the armatures than in the perpendicular direction.

Mounts operating tilted or twisted do not work properly. This may be due to incorrect alignment, tolerances in the building of the chassis or over-tightened torque during the installation of the Antivibration mounts. This applies to our marine-type, BSB, BRB or Mecanodamp mounts. RECOMMENDATIONS FOR THE CONICAL MOUNTS The conical mounts should always use the washers indicated for each model. Similarly, we recommend the use of lateral limiters for cases with high loads or radial impact. This applies to our AT, SCB, SCH or Mecanocaucho® mounts. Anti-rebound washers 70 Radial load limiters * In order to adapt its products to the state of the art, AMC S.A. reserves the right to modify the conception and manufacture of the materials presented in this catalogue without prior notice Installation principles RECOMMENDATIONS FOR THE DSD AND DRD MOUNTS Although it is not absolutely necessary, the AMC Mecanocaucho® hoods should be used in the DSD and DRD hoods. This hood distributes the load evenly in the event of overloads, and also provides protection from possible oil splashes. Care should be taken to make sure that the protective hood has the same or a greater diameter than that of the diameter of the rubber element. We have a standard range of Mecanocaucho® protection hoods. Check them out. RECOMMENDATIONS FOR THE CYLINDRICAL MOUNTS The cylindrical mounts should never work at traction. They should be used on a compression basis. To obtain greater deflection, use them at shear or shear /compression, although the maximum loads indicated in our catalogue for shear use should never be exceeded. This applies to our bobbings, diabolo, trapezoidal or annular mounts. Compression Compression-shear Shear RECOMMENDATIONS FOR MACHINES THAT REQUIRE ALIGNMENT When an alignment is required between different mechanical elements of the machine, the creeping effect should be taken into account. The increased deformation produced by the creep of the elastomer leads to a “misalignment” between suspended and rigid elements, particularly during the first 48 hours of static load in the antivibration mounts. Alignment should therefore be checked 48 hours after the installation of the machine. If this is not possible contact AMC’s technical department and they will help you to ascertain the optimal alignment of your machine. * In order to adapt its products to the state of the art, AMC S.A. reserves the right to modify the conception and manufacture of the materials presented in this catalogue without prior notice 71 RECOMMENDATIONS FOR AMC MECANOCAUCHO ® MACHINE MOUNTS WITHOUT ADJUSTABLE HOOD On installing one of our AMC Mecanocaucho® machine mounts without adjustable hood, great care should be taken to ensure that the load of the machine does not rest on the screw, but on the hood. This applies to our AMC Mecanocaucho® SV, SM and low SV series mounts. This nut distributes the load on the whole hood of the mount RECOMMENDATIONS FOR TORQUE TIGHTENING FOR THE BRB, BSB, MD AND MARINE MOUNTS Before installing, make sure that the support surfaces are sufficiently rigid Flat and totally parallel. The main fixing screw should be tightened according to the torques recommended in the following chart: Tightening torque in Nm RECOMMENDATIONS FOR THE INSTALLATION OF ANTIVIBRATION MOUNTS The position of the antivibration mounts determines the vibration modes of the suspended ensemble. An even load distribution over all the mounts is advisable. One easy way of obtaining this is by installing the antivibration mounts equidistant from the CDG of the ensemble. Mounts installed at the height of the crankshaft provide more stable suspensions and avoid over-movement of the suspended ensemble, particularly in mobile or moving applications. The external connections to the suspended ensemble, such as cables, exhaust, hydraulic pipes, etc., must be elastic enough to prevent vibrations from being transmitted to the chassis through them. 72 * In order to adapt its products to the state of the art, AMC S.A. reserves the right to modify the conception and manufacture of the materials presented in this catalogue without prior notice
