COUPLINGS
A. L, AL, C and H Types
Jaw hubs and elastomers come in many sizes and types.
First, determine the size and type of components being used. Remove all components from their boxes and loosely assemble the coupling on any convenient surface. Also check maximum RPM values in Table 2 against operating speed.
1.
Inspect all coupling components and remove any protective coatings or lubricants from bores, mating surfaces, and fasteners. Remove any existing burrs, etc., from the shafts.
2.
Slide one coupling hub onto each shaft, using keys where required. Keys should fit snugly.
3.
Position the hubs on the shafts to approximately achieve the “G” dimension shown in Table 2. It is usually best to have any equal length of shaft extending into each hub. Tighten one hub in its final position.
For style 1 or style 2, if possible, slide the other hub far enough away to install elastomer. If hub cannot be slid back, or if “blind” assembly, tighten second hub on shaft and bring equipment together.
For style 3, tighten hubs on shafts, do not install cushions and collars at this time. Tighten setscrews to the appropriate value shown in Table 1.
4.
Check parallel alignment by placing a straight edge across the two coupling hubs, and measuring the maximum offset at various points around the periphery of the coupling without rotating the coupling. If the maximum offset exceeds the figure shown under
“Parallel” in Table 2, realign the shafts.
5.
Check angular alignment with a micrometer, vernier, or caliper. Measure “X” from one hub to the other at intervals around the coupling. Determine the maximum and minimum dimensions without rotating the coupling, the difference of these two measurements must be less than the Angular value in Table 2. If a correction is necessary, be sure to recheck the parallel alignment.
B. RRS,RC, and LC Types
Determine the size and type of coupling being used. Also check maximum RPM values in Tables 2 and 3, against the operating speed. Remove all components from their boxes and loosely assemble the coupling on any convenient surface.
Step1.
Inspect all coupling components and remove any protective coatings or lubricants from bores, mating surfaces, and fasteners. Remove any existing burrs from the shafts.
Step 2.
Use appropriate section for the type of coupling assembly.

Installation Instructions
2a. For RRS Type - Styles 1, 2 and 3
1.
Slide one hub onto each shaft, using keys where required. Position the hubs on the shafts to achieve spacer gap as in Figures 3 and 4. It is usually best to have an equal length of shaft extending into each hub.
Line up the jaws of both hubs and tighten them with set screw torque from Table 1 in their final positions.
2.
Check parallel alignment by placing a straight edge across the two hubs and measuring the maximum offset at various points around the periphery of the hubs without rotating the coupling. If the maximum offset exceeds the parallel value in Table 3, realign the shafts.
3.
Check angular alignment with a micrometer or caliper.
Measure the “X” dimension from one hub to the other at intervals around the hubs. Determine the maximum and the minimum dimensions without rotating the coupling. The difference of these two measurements must be less than the angular value in Table 3. If a correction is necessary, recheck the parallel alignment.
4.
Position the spacer between the two hubs with collars loose on the hub or spacer. Install the snap-wrap spiders and fasten collars with cap screws. Proceed to Step 3.
2b. For RRC Type - Style 4.
1.
Slide one adaptor hub onto each shaft, using keys where required. Position the hubs on the shafts to achieve a spacer gap as in Figure 5. It is usally best to have an equal length of shaft extending into each hub.
Tighten both hubs with the set screw torque from
Table 1.
2.
Install the spacer section between the two hubs. The spacer section includes two jaw rings, the cushions, and a collar. Fasten the spacer section to the adaptor hubs with the axial mounting screws and torque them to 68-76 ft-lbs.
3.
Slide collar off jaw ring and set on the adaptor hub.
Some cushions at the bottom side of the coupling can fall out and may be set aside while checking shaft alignment.
4.
Check parallel alignment by placing a straight edge across the two hubs and measuring the maximum offset at various points around the periphery of the hubs without rotating the coupling. If the maximum offset exceeds the parallel value in Table 3, realign the shafts.
5.
Check angular alignment with a micrometer or caliper.
Measure the “X” dimension from one hub to the other at intervals around the hubs. Determine the maximum and the minimum dimensions without rotating the coupling.
The difference of these two measurements must be less than the angular value in Table 3. If a correction is necessary, recheck the parallel alignment.
6.
Reinstall the cushions and fasten the collar with cap screws. Proceed to Step 3.

C. LC Type
1.
Slide one hub onto each shaft, using the keys where required.
Keys should fit snugly. Position the hubs on the shafts to approximately achieve the “G” dimension. It is usually best to have an equal length of shaft extending into each hub. Tighten both hubs in their final positions using the set screw torque. Slide the collar to the edge of the hub and do not install the snap-wrap spider at this time.
2.
Check Parallel alignment buy placing a straight edge across the two hubs and measuring the maximum offset at various points around the periphery of the hubs without rotating the coupling. If the maximum offset exceeds the parallel value under NBR in Table
2, realign the shafts.
3.
Check angular alignment with a micrometer or caliper. Measure the “X” dimension from one hub to the other at intervals around the hubs. Refer to Figures 1 and 2 for Styles 1 and 2, respectively.
Determine the maximum and the minimum dimensions without rotating the coupling. The difference of these two measurements must be less than the angular value under NBR in Table 2. If a correction is necessary, recheck the parallel alignment.
4.
Install the snap-wrap spider and fasten the collar with cap screws.
Proceed to Step 3.
Note: Install coupling guards per OSHA or ASME 815.1 requirements.

COUPLINGS
Lovejoy’s commitment to continual product improvement is demonstrated in the next generation of the Jaw In-Shear (JIS) coupling—the new Jaw In-Shear 6 Pin. This new design features a unique 6 pin locking system that allows for even easier locking of the element. Lovejoy’s L-Type and CType
Jaw hubs are utilized with this design. No tools are needed, because the element is radially removable, neither hub (for the driver or driven equipment) has to be moved to replace the element.
Jaw In-Shear Couplings
JIS 6 Pin
The Jaw In-Shear 6 Pin coupling is available in bore sizes up to 9 inches. The JIS 6 Pin Spacer coupling is designed specifically as a drop-in replacement for a grid spacer coupling. The adapter hubs allow a grid spacer design to be replaced with a non-lubricated JIS 6 Pin Spacer coupling.
The JIS 6 Pin Spacer coupling is available in sizes LS090-
CS350. These sizes cover B.S.E. (between shaft end measurement) of 3.5, 5, 7, and 9 inches, depending on coupling size.

Stainless Steel
For highly corrosive, heavy washdown environments, the JIS
6 Pin design combined with Lovejoy’s stainless steel jaw hubs creates a totally stainless steel coupling.
• 2 degree angular misalignment capability.
• 0.030" - 0.094" parallel misalignment capability.
• Torsional wind-up of 5 degrees at full load.
• 50D shore Urethane material—maximum temperature of 93°C (200°F).
• The retaining ring is made from #347 cast stainless steel
• Stainless steel hubs are available for sizes SS075-SS150 from stock.
All other stainless steel hub sizes are available as made to order.
• Can be used with AL-type aluminum jaw coupling hubs for AL090/095, AL099,
100 and 110.
• The Original JIS locking ring is interchangeable with the new JIS 6 Pin

COUPLINGS S-Flex Couplings
Selection Data
Protection from misalignment, shock, and vibration:
The simple design of the S-Flex coupling ensures ease of assembly and reliable performance. No special tools are needed for installation or removal. S-Flex couplings can be used in a wide variety of applications.
Features and Benefits:
• Easy to Install.
• Maintenance Free.
• No Lubrication.
• Dampens Vibration and Controls Shock.
• Torsionally Soft.
• Double Engagement.
The S-Flex coupling design is comprised of three parts.
Two flanges with internal teeth engage an elastomeric flexible sleeve with external teeth. Each flange is attached to the respective shaft of the driver and driven and torque is transmitted across the flanges through the sleeve.
Misalignment and torsional shock loads are absorbed by shear deflection in the sleeve. The shear characteristic of the S-Flex coupling is very well suited to absorb impact loads.
The S-Flex coupling from Lovejoy offers combinations of flanges and sleeves wihich can be assembled to suit your specific application. Thirteen sizes are available with torque capabilities that range from 60 in-lb to 72,480 in-lb.
The S-Flex flanges are offered in four models which are made from zinc die cast or cast iron. Sleeves are available in
EPDM rubbber, Neoprene, or Hytrel to address a wide variety of application requirements.
Flange Types:
Type J - Zinc Die Cast and Cast Iron,
Bore Range... 3/8”-1-7/16”
Type S - Cast Iron, Bore Range... 1/2”- 5-1/2”
Type B - Cast Iron w/QD Bushing
Type SC - Cast Iron Spacer
Type T - Cast Iron w/Taper-lock bushing
Hubs for Type SC Spacer Coupling:
Type H - Powdered Metal or Cast Iron, Standard Length
Type HS - Powdered Metal or Cast Iron, Short Length
Sleeves Types:
JE (EPDM)
JES (EPDM)
JN - (Neoprene)
JNS - (Neoprene)
E - (EPDM)
N (Neoprene)
H (Hytrel)
HS (Hytrel)

The S-Flex coupling accepts up to 0.813mm of parallel misalignment without wear. The flexible coupling sleeve minimizes the radial loads imposed on equipment bearings, a problem commonly associated with parallel misalignment.
The flexing action of the elastomeric sleeve and the locking feature of the mating teeth allows the S-Flex coupling to effectively handle angular misalignment up to 1°.
The S-Flex couplings can be used in applications which require a limited amount of shaft en-float without transferring thrust loads to equipment bearings. Axial movement of approximately 3.175mm accepted.
S-Flex couplings effectively dampen torsional shock and vibration to protect connected equipment. The EPDM and
Neoprene sleeves have torsional wind-up flexibility of 15° at their rated torque. Hytrel provides 7° wind-up.
