Basic Information
Safety Notes
Falk Gear Drives — The Falk and Rexnord name on the gear drive is the
purchaser’s assurance that the drive was engineered, rated and manufactured
to sound design practices. When one prime mover drives two pieces of
equipment, one of which is either a standard Rexnord geared drive or a
customer standard geared drive, the division of power between each machine is
the responsibility of the customer. The power supplied to the geared drive must
be equal to or less than the power for which the drive was selected using the
appropriate service factor for the application. The customer must also assume
the responsibility of isolating the gear drive from any vibratory or transient load
induced by the driven equipment.
Install and operate Rexnord products in conformance with applicable local and
national safety codes and per Rexnord installation manuals which are shipped
with gear drives and are also available on our website at www.rexnord.com.
Suitable guards for rotating members may be purchased from Rexnord as
optional accessories. Consult your local Rexnord Representative for complete
details.
People Conveying Equipment — Selection of Rexnord gear drives for
applications whose primary purpose is the transportation of people is not
approved. This includes such applications as freight or passenger elevators,
escalators, man lifts, work lift platforms and ski tows and ski lifts.
If the primary purpose of the application is material conveyance and
occasionally people are transported, the Rexnord warranty may remain in effect
provided the design load conditions are not exceeded and certification to the
appropriate safety codes and load conditions has been obtained by the system
designer or end user from the appropriate enforcement authorities.
Gear Drive Ratings — All gear drive ratings in this bulletin allow 100% overload
for starting loads and momentary overloads for electric motor driven applications
operating 10 hours per day under uniform conditions. For other conditions,
compute an equivalent horsepower by multiplying the actual horsepower required
for the application by the appropriate Service Factor.
Gear Drive Identification — Tables in this selection guide identify gear drives
based on the drive nomenclature.
Horsepower & Torque/Gearmotor Drives — Gearmotor Drive mechanical
horsepower and delivered torque ratings are tabulated only at 1750 rpm.
Horsepower, output torque, and LSS OHL ratings for Gearmotor Drives do not
always correspond to those of the comparable Inline Gear Drive of the same
size, reduction, and ratio.
In selected cases the Gearmotor Drive will have more rating than the
corresponding Inline Gear Drive. When additional rating for Gearmotor Drives at
1750 rpm input is available, it will be as stated in the Gearmotor Drive Selection
Tables. For Gearmotor Drive ratings at input speeds other than 1750 rpm,
consult the Factory.
Horsepower & Torque/Gear Drives — Gear Drive mechanical horsepower and
output torque ratings are tabulated in the Selection Guide to permit selections for
specific application requirements. When the required input speed falls between two
tabulated input speeds of a specific drive designation (size, reduction and ratio),
interpolate to determine drive rating.
Lubricants — Drive Sizes 201 thru 207UC will be supplied filled with a quantity
of EP mineral oil suitable for the drive mounting position specified at the time
of the order.
Drive Sizes 208 thru 10UC are supplied without lubricant. The appropriate fill
quantities and lubricant recommendations are stated in Manual 288-100.
Stored & Inactive Gear Drives — Each gear drive is protected with rust
preventive that will protect parts against rust for a period of 6 months in an
indoor dry shelter.
Sizes 208 thru 10UC — If a gear drive is to be stored, or is inactive after
installation beyond the above periods, drain oil from housing and spray all
internal parts with a rust preventive oil that is soluble in lubricating oil or add
“Motorstor”™ vapor phase rust inhibitor at the rate of one ounce per cubic foot
of internal drive space (or 5% of sump capacity) and rotate the shafts several
times by hand. Before operating, drives which have been stored or inactive must
be filled to the proper level with oil meeting the specifications given in Manual
288-100. Refer to Manual 128-014 for “Start-up after Storage” instructions.
Periodically inspect stored or inactive gear drives and spray or add rust
inhibitor every six months, or more often if necessary. Indoor dry storage is
recommended.
Gear drives ordered for extended storage can be treated at the Factory with
a special preservative and sealed to rust-proof parts for periods longer than
those cited previously.
Factory Warranty — Factory products generally carry a limited, one-year
warranty against defects in materials or workmanship; but for an actual
statement of the Factory Warranty, ask your local Representative or Distributor
for our Standard Conditions of Sale.
See warranty statement 100-003 on our website www.rexnord.com.

Conditions Affecting Selection
Non–Standard Application Procedures
The following conditions may affect the gear drive selection procedure, drive
size and auxiliary equipment being furnished.
Excessive Overloads — The maximum momentary or starting load must not
exceed 200% of rated load (100% overload). Rated load is defined as gear drive
rating with a Service Factor of 1.0. If the maximum starting or momentary load
exceeds the above conditions, compute a second equivalent horsepower by
dividing the peak load by two. The gear drive selected must have capacity equal
to, or in excess of, the larger equivalent horsepower.
Reversing Service — Applications involving either more than 20 reversals per
10 hour period, or less than 20 reversals per 10 hour period with peak torques
greater than 200% of normal load must be referred to the Factory.
Stop and Start Service — Applications involving frequent stop and start
overloads in access of 10 times per day must be referred to the Rexnord
Factory.
Brake Equipped Applications — When a gear drive is equipped with a
“working” brake that is used to decelerate the motion of the system and the
brake is located between the prime mover and the gear drive or on the rear of
the motor, select the drive based on the brake rating or the highest equivalent
horsepower, whichever is greater. If the brake is used for holding only and is
applied after the motion of the system has come to rest, the brake rating must
be less than 200% of the catalog rating, refer the application to the Factory.
Also refer to the Factory all applications in which the brake is located on the
output shaft of the gear drive.
Oversize Prime Mover — Published Service Factors do not cover applications
that require oversize prime movers for high energy or peak loads. Refer such
applications to the Factory for selection of suitable drives.
Speed Variation — Gear drives offered in this Selection Guide are designed
to operate with splash lubrication at all speeds for which they are catalogued,
provided the appropriate amount of lubricant is present based on the drive
mounting position (Refer to Manual 288-100 for oil quantity associated with
each gear drive mounting position). Variation of speed between cataloged
speeds, or at speeds falling between catalogued speeds, is permissible.
Lubrication of Sizes 201 thru 207UC — These sizes are furnished filled with
a quantity of oil. Quantity of oil furnished is based on the customer identified
drive mounting position stated at the time of order. Standard drive mounting
positions are shown in this selection guide. These sizes have no oil fill plug,
oil drain plug, or vent plug. Standard oil furnished with the gear drive is a
petroleum based extreme pressure lubricant conforming to AGMA Viscosity
Grade 6EP, ISO Viscosity Grade 320, and no further lubrication of the gear drive
is required.
Lubrication of Sizes 208 thru 10UC — These sizes are furnished without oil.
Customer oil fill is required. They are furnished with
oil fill plug, oil drain plug, and vent plug. Lubricant quantity lubricant
specifications, location of plugs, and recommended oil change frequency are
stated in the Installation & Maintenance Guide 288-100.
Variable or Multi–Speed Applications – All Types — When selecting gear
drives for multi-speed or variable speed application, determine the speed which
develops the greatest torque and select the drive on this basis. If the speed is
not listed in the selection table, use the next lower speed.
Effects of Solar Energy — If a drive operates in the sun at ambient
temperatures over 100°F, then special measures must be taken to protect the
drive from solar energy. This protection can consist of a canopy over the drive
or reflective paint on the drive. If neither is possible, a heat exchanger or other
cooling device maybe required.
Overhung Loads and Thrust Loads — The overhung load and thrust load
ratings published in this bulletin are based on a combination of the most
unfavorable conditions of rotation, speed, direction of applied load and drive
loading. If the calculated load exceeds the published value, or if an overhung
load and thrust load are applied simultaneously to a shaft, refer complete
application information to the Rexnord Rexnord factory.
Non-Standard Mounting Positions — For non-standard mounting positions
(other than those shown in this Selection Guide) refer to the Rexnord factory
for lubricant level and quantity.
Double Seal Option — Certain applications may dictate the use of double
seals. This option, provided at an additional charge, is furnished as follows:
Gearmotors — A double seal is available only at the low speed shaft.
Inline Drives — A double seal is furnished at both the high speed and low
speed shafts.

Application: Belt conveyor, heavy duty, head shaft speed is 24 rpm, ambient
temperature of 86°F base mounted drive configuration is specified.
Duty Cycle: 16 hours per day.
Driver: 1/2 hp electric motor, 1750 rpm, 56C frame.
Output: 3” pitch diameter sprocket with a 2:1 chain drive. Sprocket is mounted
on gearmotor output shaft such that the centerline of the overhung load is at
the midpoint of the output shaft extension.
1. Service Factor from Page 9 is 1.50.
2. Motor Horsepower is .5 hp.
3. The head shaft speed must be multiplied by the chain drive ratio to obtain
the drive output rpm (24 x 2 = 48 rpm) and ratio (1750 ÷ 48 = 36:1).
4. From selection guide on Page 40, the appropriate gearmotor is the Size
202UCBN2A36.A_A, part number 4767286 (base mounted), exact ratio
35.69:1, 2.26 service factor, and permissible overhung load equals 899 lb.
5. Check Thermal Rating — From Page 81, the thermal hp rating is 7.8
hp. Since the ambient temperature is 86°F you must apply an ambient
adjustment factor to determine the application adjusted thermal rating.
Application adjusted thermal hp = 7.8 x .86 = 6.7hp
The application adjusted hp rating of the gearmotor exceeds our motor hp
requirements.
6. Overhung Load Check — Allowable overhung load from Page 40 is 899 lb.
Calculate overhung load per instructions on Page 70.
OHL = 126000 x .5 hp x 1.00 x 1.00 = 438 lb
3 x 48
The overhung load capacity of the gearmotor exceeds our calculated
requirements.
7. Check External Thrust Load Capacity on Page 72 — For this example there
is no external thrust.
8. Check Dimensions on Page 62.
9. Specify Drive Mounting Position and Motor Mounting Position (If Mounted
Motor is Requested) from Page 12 — For our example, the gearmotor is
mounted in drive mounting position #1, flat on the floor.
Regarding mounting of NEMA C – Face motors, the most common motor
mounting position is “C”, with the nameplate upward and the conduit box
wiring hole down.

Determine Service Factor — See Pages 8 & 9.
Determine Motor Horsepower.
Determine Gearmotor Output Speed and Ratio.
Gearmotor Selection tables are included on Pages 17 through 23 and
36 through 61. These tables assume a motor base speed of 1750 rpm.
For ratings at other motor base speeds, consult your authorized Sales
Representative.
Go to the page that contains selections based on the specific C – Face
motor you will be using. For example, selections for .50 hp, 1750 rpm, 56C
frame motors are tabulated on Pages 40 & 41.
Starting at the top of the first selection page pertinent to your motor
requirement, move down the selections until a gearmotor meeting your
output speed, ratio, reduction, and service factor requirements is located.
For example consider an application with a .50 hp, 1750 rpm/56C frame
motor, output speed of 47 rpm, nominal ratio of 36:1, and a required
service factor of 2.00.
Pages 40 & 41 contains selections for a .50 hp, 1750 rpm/56C frame motor.
The Gearmotor 202UCBN2A36.A_A (base mounted) has an output speed
of 48 rpm, exact ratio of 35.69:1, double reduction, and a service factor of
2.26 which meets our requirements. Choose your required configuration,
a base mounted or flange mounted gearmotor and record the full
nomenclature & part number.
Check thermal Rating — The application adjusted thermal rating must be
equal or exceed the actual power transmitted(.50 hp). Ratings are based
upon an ambient temperature of 68°F. If the actual ambient is different
an ambient adjustment factor must be applied. Basic thermal ratings and
ambient adjustment factors are included on page 81.
Check Overhung Load — The gearmotor selection tables provide the low
speed shaft overhung capacity of the gearmotor selected. If overhung load
is present, calculate the value of the overhung load per instructions on
Page 70. Sprockets or other devices mounted on the output shaft of the
gearmotor should be sized and positioned so the gearmotor overhung load
capacities are not exceeded. Should applied overhung loads exceed the
capacity of the initial gearmotor selected, a larger gearmotor of adequate
capacity must be selected.
Check External Thrust Load — Permissible thrust loads are provided
on Page 72. If thrust and overhung loads are applied simultaneously, or
if loads exceed stated thrust capacities, consult your authorized Sales
Representative.
Check Gearmotor Dimensions — Pages 62 through 69.
When ordering, provide the gear drive mounting position from Page 12. If
a mounted motor is ordered, specify motor mounting position, also from

Type UC Service Factors
A gear drive is rated to a specified application by the use of Service Factors.
Each application has its own conditions and operating requirements. These have
been analyzed and catalogued. Numerical values, based on field experience,
have been assigned to these classifications for intermittent service of 3 to 10
hours per day and for service over 10 hours per day and also for the type of
prime mover . . . electric motor or engine. Values for most applications are
listed by Application on Page 9,Table 3 and by Industry at right, Table 2.
Examples — A comparison of three different applications, each operating
16 hours per day, will illustrate the function of Service Factors: an Assembly
Conveyor, uniformly loaded (SF

relatively more severe than that of a
uniformly loaded Assembly Conveyor, etc.
Since most industrial applications are electric motor driven, Service Factors are
based on the use of electric motors. These factors can be easily converted to
engine-drive factors as outlined in Table 1.
Service Factors are based on the assumption that the system is free of dynamic
vibrations, as explained in the warranty section, and that maximum momentary
or starting loads do not exceed 200%of the rated load.
Service Factors listed are recommended as minimum for general purpose use.
Application of these service factors will result in normal drive reliability and
life under typical operation conditions. Refer to the Factory any application not
listed in Tables 2 or 3.
Applications involving unusual operating conditions or requirements such as,
but not limited to, the following should also be referred to the Factory:
• Applications requiring extended life/High reliability exceeding normal
• High frequency starting
• Stalling or other high energy load absorption
• Torsional vibrations
• Frequent speed variations
• Reversing loads
• Extremes in ambient temperature
Occasional & Intermittent
Service or Engine Driven Applications
For multi-cylinder engine driven applications and all applications operating
intermittently up to 3 hours per day, refer to Table 2 or 3 for the Service Factor
of the same application operating 3 to 10hours per day. Next, in the first
column of Table 1, find this same Service Factor in bold face type. Then, to the
right, under the desired hours service and prime mover, locate the converted
Service Factor.
For example, from Table 3, the Service Factor is 1.25 for a uniformly loaded belt
conveyor. From Table 1, for the same application the following are the Service
Factors for various conditions.
1. Engine driven 3 to 10 hours per day; use 1.50 Service Factor.
2. Engine driven up to 3 hours intermittently; use 1.25 Service Factor.
3. Motor driven up to 3 hours intermittently; use 1.00 Service Factor.

UC – Motor Adapters
The ULTRAMITE concentric gearmotor accommodates NEMA (Input Type “A”) or IEC (Input Type “G”) motor frame sizes.
Tables 6 & 6A below and 7 on the next page identify the appropriate motor adapter symbol that pertains to specific
motor frame size, drive size, ratio, and reduction combinations. If a motor adapter symbol is not listed for a particular
combination of motor frame size, drive size, ratio, and reduction, then that combination is not offered.
For Gear Drives (Inputs Types “N” and “C”), the motor adapter symbol is not used.

UC — Low Ratio Overhung Loads
High & Low Speed Shaft
Overhung load is imposed upon a shaft when a pinion, sprocket or sheave is
used as a power take-off. The magnitude of the load varies with the type of
take-off and its proximity to the shaft bearing. Calculate the load and check the
result against the tabulated overhung load rating.
Overhung load formula:
Overhung Load = 126,000 x hp x Fc x Lf
Pitch Dia x rpm
Fc = Load Connection Factor.
Gearmotor Overhung Load Capacity — The overhung load capacity at the low
speed shaft is found in the Selection Tables on Pages 17 through 22.
Gear Drive Overhung Load Capacity — The overhung load capacity at the high
speed shaft and low speed shaft are found on Page 27.
Example:
Gear Drive Size = 04UCBN2A40.N_, exact ratio of 39.37:1.
Motor = .50 hp at 1750 rpm.
Low speed shaft rpm = 1750 ÷ 39.37 = 44.4 rpm.
3” diameter sprocket mounted on low speed shaft. Centerline of sprocket
overhung load is positioned at B = 0.98 inches. Calculate the overhung load as
follows:
Sprocket or Timing Belt. . . . . . . . . . . . . . . . . . . . . . . . . . 1.00
CENTER LINE
OF LOAD
Machined Pinion & Gear. . . . . . . . . . . . . . . . . . . . . . . . . 1.25
V-Belt. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1.50
HOUSING
OHL = 126,000 x 50 x 1.00 x 1.00 = 473 lb
3 x 44.4
Flat Belt. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2.50
Lf = Load Location Factor.
DISTANCE
Allowable OHL on Page 27 is 770 lb and is satisfactory for this selection.
For overhung loads applied at the
midpoint of the usable shaft
extension, L = 1.00
f
Locate the centerline of the load as close to the drive housing as practical to
minimize the overhung load and increase bearing life. The above overhung load
formula employs the transmitted horsepower, without Service Factor, providing
the overloads, starting loads, and brake capacities do not exceed the amounts
listed in Basic Information on Page 3.
Consult Factory for Higher Overhung Load Ratings — In many cases,
overhung load capacity in excess of that published is available. Published
ratings are based on a combination of the most unfavorable conditions of
rotation, speed, direction of applied load, and drive loading. If the actual load
should exceed the published capacity, refer full details to the Factory; provide
complete application information, as well as direction of rotation, location and
direction of applied load.

UC — Overhung Loads
High & Low Speed Shaft
Overhung load is imposed upon a shaft when a pinion, sprocket or sheave is
used as a power take-off. The magnitude of the load varies with the type of
take-off and its proximity to the shaft bearing. Calculate the load and check the
result against the tabulated overhung load rating.
Overhung Load Formula:
Overhung Load = 126,000 x hp x Fc x Lf
Pitch Dia x rpm
Gearmotor Overhung Load Capacity — The overhung load capacity at the low
speed shaft is found in the Selection Tables on Pages 19 through 23.
Gear Drive Overhung Load Capacity — The overhung load capacity at the high
speed shaft and low speed shaft are found on Page 27.
Example:
Gear Drive Size = 04UCBN2A40.N_, exact ratio of 39.37:1.
Motor = .50 hp at 1750 rpm.
Low speed shaft rpm = 1750 ÷ 39.37 = 44.4 rpm.
3” diameter sprocket mounted on low speed shaft. Centerline of sprocket
overhung load is positioned at B = 0.98 inches. Calculate the overhung load as
follows:
Fc = Load Connection Factor.

DISTANCE
Lf = Load Location Factor.
Allowable OHL on Page 27 is 770 lb and is satisfactory for this selection.
For overhung loads applied at the midpoint of the
usable shaft extension, Lf = 1.00
Locate the centerline of the load as close to the drive housing as practical to
minimize the overhung load and increase bearing life. The above overhung load
formula employs the transmitted horsepower, without Service Factor, providing
the overloads, starting loads, and brake capacities do not exceed the amounts
listed in Basic Information on Page 3.
Consult Factory for Higher Overhung Load Ratings — In many cases,
overhung load capacity in excess of that published is available. Published
ratings are based on a combination of the most unfavorable conditions of
rotation, speed, direction of applied load, and drive loading. If the actual load
should exceed the published capacity, refer full details to the Factory; provide
complete application information, as well as direction of rotation, location and
direction of applied load.

Thermal Ratings (HP)
Thermal ratings are a measure of the units ability to dissipate heat, if they are exceeded the lubricant may break down resulting in premature gear failure.
Thermal ratings are based on an ambient temperature of 68ºF, when units are to operate at other ambient temperatures the thermal HP ratings must be multiplied by
the following factors.

Gearmotor Backstop Module
Gearmotor backstop modules can be fitted between the gear drive and motor. The backstop device incorporates high quality centrifugal lift off sprags which are
wear free above the lift off speed (rpm). To ensure correct operation motor speed must exceed lift off speed. Suitable for ambient temperatures of -40°F to 122°F
(-40°C to 50°C). When a backstop module is furnished, dimension K should be added to the overall length of the gearmotor assembly.
Low speed shaft rotation must be specified when ordering as viewed from the low speed shaft end.
