Step 5: Reducer Selection
Using the service factor obtained in Step 4, calculate the equivalent HP by multiplying the motor HP to be transmitted by
the service factor. The electric motor nameplate rating should be used for the demand HP.
Equivalent Hp = Motor Hp x Service Factor
Step 6: Selection
Reducer Selection:
From rating tables in this catalog make reducer selection based on input RPM, ratio, and equivalent Hp.
Step 7: Check overhung loads by using the following formula
OHL =
126,000 x Hp x K
PD x RPM
Where: OHL =
Hp =
K
=
PD =
RPM =
Overhung load (lbs)
Demand Horsepower
Load Connection Factor
Chain Drive: Fc = 1.00
Spur or Helical Gear: Fc = 1.25
Synchronous Belt Drive: Fc = 1.30
V-Belt Drive: Fc = 1.50
Flat Belt: Fc = 2.50
Pitch Diameter (inches)
Revolutions Per Minute (output)
The calculated OHL must be less than the allowable OHL.
To minimize overhung load and increase bearing life, the load center line should be located as close to the shaft shoulder
as possible. For applications where OHL exceeds catalogued values use the reducer selection tables to select the next
largest size gear case or contact your Baldor Sales Office.

Applications which expose the gear drive to high starting torques, extreme repetitive shock, or where high energy loads
must be absorbed as when stalling, require special consideration. Service factors for the special applications should be
agreed upon by the user and Baldor since variations of the values in the chart may be required.
The service factors in the service factor table are based on the use of an electric or hydraulic motor or the use of a steam
or gas turbine as a prime mover. If the prime mover is a single or multi-cylinder engine, then the service factor must be
adjusted in accordance with the chart below.

Do not mix oils from different manufacturers. If a change to another type or brand of oil is made, the existing lubricant
should be drained and the gear case flushed with a small quantity of the new lubricant before refilling with the new
lubricant. This is necessary to avoid possible incompatibility problems between the two lubricants. The list below gives
approved alternative lubricants. This is not an exclusive list. Equivalent lubricants from other manufacturers may be used.

* Ambient temperatures listed are for lubricant only and do not indicate a particular gear unit’s suitability to run in that ambient.
Recommendations will be made based on specific application details.
** Requires Viton Seals
LONG TERM STORAGE
If the drive is not installed immediately, it should be stored in a clean, dry, protected area. During periods of long term
storage (six months or longer) special procedures must be followed. The unit should be filled to the highest oil level
hole with an approved lubricant blended with 2%, by volume, of “Daubert Chemical Co. Nox-Rust VCI-105” oil. Apply a
thick coating of rust preventative on all unpainted surfaces including threads, bores, keyways, and shafts. Apply a thick
coating of chassis-type grease to all exposed shaft seals. If the unit is to be stored outdoors or in a damp, unheated area
indoors, cover the entire exterior with a rust preventative. Seal the unit in a moisture proof container or wrapping with a
desiccant inside. Shade the enclosure from direct sunlight. Rotate the input shaft at least 60 revolutions once a month to
redistribute the lubricant and prevent brinelling of bearings and drying of seals.
Upon removal from storage, remove all protective coatings applied for protection during storage. Check all hardware for
proper tightness. Drain and refill the gear reducer with a recommended lubricant. If the gear reducer has been stored for
more than three years or in an area with high ambient temperatures, replace the oil seals.

Ambient temperatures listed are for lubricants only and do not indicate a particular gear unit’s suitability to run in that
ambient.
All reducers are factory filled according to the mounting position indicated on the order. If the mounting position is
changed from the ordered mounting position, the oil level must be changed. The oil volumes shown in the mounting
position charts are approximate. The correct oil level is determined by the oil level hole in the housing except for size
38 reducers. If the reducer is ordered with the standard mineral oil and the oil is later changed to synthetic oil, it is
recommended the shaft seals be changed to Viton (FKM) material.
ILH reducers are furnished with oil level, drain, and fill plugs except for the size 38, which only has a fill plug. Before
starting operation, the breather must be located in the correct location.
Continued operation in cold ambient conditions requires special modifications. Please contact your local Baldor Sales
Office.

Baldor reducers can be modified to permit mounting in positions other than the standard mounting positions shown in
the mounting position charts including inclined and tilted positions. Consult application engineering to determine what
modifications are required for your specific application.

In order for Baldor to make recommendations on the required modifications, the following information must be provided:
• Reducer Size
• Ratio
• Input and/or Output speed
• Transmitted Horsepower
• Duty Cycle — Continuous vs. intermittent operation. If intermittent, running time vs. idle time.
• Mounting position, such as A1, A2. . . A6 with shafts level, a complete description of the mounting arrangement
including the angle of tilt of the housing, the incline of the shafts and whether the output shaft is higher or lower than
the input shaft.

For the example shown here – the unit would be called out with a CW rotation from a A1 mounting position of 30 degrees
(Angle º). This illustration represents a typical arrangement for a tilted reducer. The proper oil level will vary with reducer
size, ratio, input speed and angle of tilt. Contact your local Baldor Sales Office.

The data in the table below lists the permissible output shaft overhung load (OHL) when the load is located at med-shaft. To calculate the permissible OHL when the
load is located at other positions, use the formulas above along with the data below.
Both equations 1 and 2 must be used to determine if the bearing or shaft strength limits the OHL. Limit the OHL to the lower of the 2 calcuations.

REQUIRED INFORMATION
SELECTION EXAMPLE
To select the proper reducer for a given application, several
important factors should be taken into consideration. They are:
Application, Horsepower, Torque, Ratio and Overhung Load.
Selection the correct C-flange (motorized) reducer to drive a
package conveyor, based on the following requirements.
Note: See Engineering Information page 185 for detailed
information and calculations on horsepower, torque, ratio and
overhung load.
The horsepower, torque and overhung load ratings shown in the
catalog are based on a service factor of 1.0. For applications
conforming to a 1.0 service factor, the catalog ratings may be
used directly. For applications not conforming to a 1.0 service
factor, the catalog rating must be divided by the appropriate
service factor from the service factor table. The catalog ratings
may be used directly if the actual application horsepower and
torque requirements are multiplied by the appropriate service
factor.

CLASS OF SERVICE (APPLICATION)
Prime
Mover
a. Eight hours continuous service per 24 hours, no shock
loading.
1.25
1.50
1.75
2.00
d. 4.193” pitch diameter sprocket on output shaft.
e. Input worm over single left-hand output shaft, floor mount.
Step 1. Eight hour service, no shock loading indicates use of
1.00 service factor.
Step 2. 1 HP x 1.00 service factor = 1.00 design HP.
875 in. lbs. x 1.00 = 875 in. lbs. output torque capacity
required.
Step 3. Determine ratio:
Input RPM 1750
Ratio =
=
= 30.2, use 30:1
Output RPM 58
Step 4. Refer to catalog rating tables, smallest unit capable of
handling 1.00 input HP, 875 in. lbs. output torque at
30:1 ratio is size 258.
Step 5. Determine whether overhung load of drive exceeds
capacity of reducer selected;
OHL = Torque x K 875 x 1.00 =
= 418 Lbs*
r (sprocket radius)2.097
See Engineering pg. 185 for Constants
418 pounds is well below the 900 pounds overhung
load rating of the reducer selected.
Step 6. Worm over, left hand output extension conforms to
Assembly Type B. Use STF-258-30-A-B which has a
30:1 ratio and a motor mounting flange and input bore
to accommodate a NEMA 56C motor.
As an alternative to the above, a two-to-one sprocket reduction
could be used. With a 21-tooth sprocket on the output shaft
and a 42-tooth sprocket on the driven shaft, the torque at the
reducer output has been cut in half to 438 lb. in. The reducer
ratio requirement has also been cut in half to 15:1. (15:1 reducer
x 2:1 sprocket set = 30:1 total)
Now the drive requires a reducer of 15:1 ratio, 438 lb. in. torque
capability and an overhung load of 209 lbs.
SELECTION PROCEDURE
Step 1. Select appropriate service factor.
Step 2. Multiply actual application output torque or horsepower
required by service factor to obtain design horsepower
or torque.
Step 3. Determine appropriate reducer ratio based on input
speed and required output speed.
Step 4. Select proper size reducer, based on horsepower and/
or torque, service factor and ratio.
Step 5. Determine whether overhung load capacity of reducer
selected exceeds actual overhung load of drive.
Step 6. a.Determine proper mounting arrangement.
b.For C-flange (motorized) reducers determine proper
catalog designation to accommodate the frame
number of the number of the motor to be used.
OHL =
438(T) x 1(K)
= 209 lbs. (See Engineering
pg. 185)
2.097 (sprocket radius)
This requirement can be filled by Baldor’s STF-200-30-A-B. It
has an output torque capacity of 605 lbs. in. and an overhung
load rating of 600 lbs.
By using the 2:1 secondary sprocket reduction, the reducer size
has been reduced to two full sizes and an approximately 25%
reduction in reducer cost.
*If using output horsepower instead of torque to determine overhung load, use formula:
OHL = HP x 63,025 x K = (See Engineering pg. 185)

MECHANICAL RATING
Endwise movement of input or output shafts, sometimes
called endplay, is usually expressed in thousands of an inch.
BACK-DRIVING
This is the converse of self-locking. Depending upon ratio
and many variables, it is difficult to predict the back-driving
capability. Worm gear reducers are not intended to be used as
speed increasers. Consult factory for back-driving applications.
Rotational movement of the output shaft when holding the
input shaft stationary and rotating the output shaft alternately
clockwise and counter clockwise. Backlash may be expressed
in thousands of an inch measured at a specific radius at the
output shaft.
CENTER DISTANCE
The distance between the center lines of the input and
output shafts. The center distance of multiple stage reducers
usually refers to the lowest speed stage (last reduction).
EFFICIENCY
Efficiency is the ratio of output power to input power. It is
usually stated as a percentage.
Input HP = 2
Output HP = 1.6
(1.6 ÷ 2) x 100 = 80% Efficiency
The maximum power or torque that a speed reducer
can transmit, based on the strength and durability of its
components, is its mechanical rating. Obviously, the reducer
may be rated no higher than the strength or durability of its
weakest component. Reducers typically have a safety margin
of two to three on their mechanical ratings. Thus, a reducer can
withstand momentary overloads of 200-300% of its mechanical
rating during a startup or other brief overload situation.
MOUNTING POSITION
BACKLASH
Example:
The relationship of the input and output shafts relative to
the floor line is the mounting position.
OVERHUNG LOAD
The input or the output shaft of a speed reducer can be
subject of an overhung load; that is, to a force applied at right
angles to the shaft, beyond its outermost bearing. Such a force
is a shaft bending load resulting from a gear, pulley, sprocket or
other external drive member. Besides the tendency to bend the
shaft, the overhung load (that is, the radial force on the shaft) is
reacted to by the shaft in its bearings. Therefore, the overhung
load creates loads that the bearings must be able to support
without damage.
PRIME MOVER
The machine that provides power to a drive is its prime
mover. The most frequently encountered prime movers include
electric motors, internal combustion engines, hydraulic motors
and air motors. The type of prime mover used can affect the
speed reducer during operation. For example, an electric
motor runs relatively smoothly in comparison to an internal
combustion engine.

The amount of power available at the output shaft of
a reducer is its output horsepower. Due to losses caused
by inefficiency, output horsepower is always less than input
horsepower.
Accessories
AXIAL MOVEMENT
OUTPUT HORSEPOWER
Ratio Multiplier
The amount of power applied to the input shaft of a
reducer by the prime mover is its input horsepower. It is often
used as a selection basis for power transmission components,
and it appears in the rating tables of drive manufacturer’s
published data. Remember that input horsepower ratings
represent the maximum amount of power that the reducer can
safely handle.
In-Line Helical (ILH)
The American Gear Manufacturers Association (AGMA)
is composed of member companies who manufacture speed
reducers, enclosed gear drives, open gearing, and gear type
shaft couplings, and an equally large number of technical
members (domestic and foreign) who use these products or
supply tools, machines, or other products to the gear industry.
Together, they establish standards to help standardize the
design and application of gear products. The work done
by AGMA over the years has greatly advanced the quality
and standardization of gearing. The combined experience of
company members and technical members assures gear users
that products built, selected, and applied in accordance with
AGMA standards will perform well.

RATIO
THERMAL RATING
The ratio of a drive is based on the relationship of its input
shaft speed to its output shaft speed. It is commonly expressed
as a proportion.
The maximum horsepower or torque that a speed reducer
can transmit continuously, based on its ability to dissipate heat
generated by friction, is called its thermal rating.
SELF-LOCKING ABILITY
THRUST LOAD
Self-locking ability is the ability to hold a load at rest.
Baldor does not guarantee its worm reducers to be self locking.
A brake or other device should be used to hold the load.
Force imposed on a shaft parallel to the shaft axis is called
a thrust load. It is often encountered on shafts driving mixers,
fans, blowers and similar machines. When a thrust load acts on
a speed reducer, you must be sure that the thrust load rating
of the reducer is high enough that its shafts and bearings can
absorb the load.
SERVICE FACTORS
Accessories
Ratio Multipliers
Numbers which modify the loads which must be
considered in selecting a speed reducer are called service
factors. They vary with the type of service in which the reducer
is to be used, the kind of prime mover involved and the duty
cycle. The service factor can be a multiplier applied to the
known load, which redefines the load in accordance with the
conditions at which the drive will be used. Or it can be a divisor
applied to catalog reducer ratings, thus redefining the rating in
accordance with drive conditions. The service factor is usually
applied to the speed reducer, but can also be applied to the
nameplate rating of the prime mover.
TORQUE
A twisting effort exerted around an axis is called torque. It
is the product of a force and its distance from the axis around
which the force acts.

The service factors in the service factor table are based on the use of an
electric or hydraulic motor or the use of a steam or gas turbine as a prime
mover. If the prime mover is a single or multi-cylinder engine, then the
service factor must be adjusted in accordance with the chart below.
The applications and service factors are in accordance with the current AGMA Standard 6034-E87. This list is not all-inclusive and
each application should be checked to determine if any unusual operating conditions will be encountered.

2. Tighten the supplied 4 bolts with lockwashers evenly for a
solid fit between motor and “C” flange.
C-Flanged reducers with hollow worm bore require attention
to be sure that the key has maximum contact in the keyslots of
both the input worm bore and the motor shaft. When mounting
the motor to the reducer, the key should be inserted in the
keyslot of the worm bore, not in the keyslot of the motor shaft.
Bolts and lockwashers for fastening the motor to the reducer
are supplied with all Baldor C-Flanged Reducers and should be
tightened securely and evenly to help avoid misalignment.
Flexible Coupling Input
STEP #1.Mount one coupling half on motor shaft so that
coupling half and end of key are flush with end of
motor shaft. (See Drawing A)
When mounting a sprocket, gear, or sheave, etc., on a reducer
shaft, mount the working face as close to the reducer housing
as possible. The gear or sprocket hub should be nearer the
end of the shaft as shown in the illustration. Be careful not to
damage the reducer oil seal when mounting the sprocket, gear,
or sheave.
STEP #2.Tighten coupling setscrews. Thread locking
compound is recommended on all coupling
setscrews. Measure distance from inner face of
coupling to motor mounting surface. (See Drawing A)
STEP #3.Mount other coupling half on the reducer input shaft
so the coupling end measures the same distance to
the mounting surface of the “C” flange. (See Drawing
B) Tighten setscrews. Key should be flush with shaft
end. Use pipe plug opening in side of “C” flange to
loosen, tighten or make any adjustments in coupling
position.
STEP #4. Align coupling halves and install motor.
STEP #5. Rotate motor to require position and tighten the
supplied four bolts and lockwashers evenly for a
solid fit between motor and “C” flange. Re-install and
tighten the pipe plug in the flange access hole.
Installing in this manner reduces the load on the shaft and
increases bearing life.
To reduce unnecessary load and obtain maximum reducer and
component life, driving and driven sprockets or sheaves should
be properly aligned with their mates and all shafts parallel. Gears
should be mounted on shafts at the proper center to center
distance.

ALIGNMENT – When installing Baldor Reducers, care should be
taken to align input and output shafts vertically and horizontally
with connecting shafts. A flat and even mounting surface will
help prevent uneven base hole bolt pressures. Flexible couplings
will help compensate for minor variations in shaft alignment.

Reducers filled with Kluber Klubersynth UH1-6-460
synthetic lubricant are ready for immediate use. These
reducers are completely sealed and require no breather
vents. The design and synthetic lubrication allow efficient
operation to reduce operating temperature and minimize
internal pressure build up. The reducer has been filled
with the correct amount of oil for all approved mounting
positions. Do not add or remove any oil during installation
or after the break-in period.
Accessories
Ratio Multipliers
Mount the reducer on a flat surface, to assure proper bolt
tension and prevent damage to the mounting base. When
direct coupling the reducer to the driven machine, carefully
align the reducer output shaft to the input shaft of the
driven machine. These shafts must be connected with a
flexible coupling.
In-Line Helical (ILH)
Power transmission components, such as sprockets,
gears, or sheaves, mounted on the reducer shafts
produce overhung loads. Mount these components
as close as possible to the reducer with the hub facing
outward. This mounting minimizes the load on the reducer
shaft and bearings for increased life. Carefully align
these components with their counterparts on the driven
machine.
mounting positions
Because Baldor speed reducers do not require a breather
vent, they are suitable for mounting in a wide variety of
mounting positions without modification.
Avoiding those positions where the high-speed (input)
oil seal is immersed in oil, will provide greater security
against high-speed (input) seal wear. For maximum seal
life, the reducer should be mounted with the highspeed (input) shaft as high as possible above the
low-speed (output) shaft. Since the high-speed (input)
oil seal experiences more revolutions than the output, it
will also experience more heat and more wear. When the
speed reducer is mounted in a manner where the highspeed (input) seal is below the oil level, and the seal is
nearing the end of it’s useful life, the steady head of oil on
the seal will result in a leak. If the reducer is mounted with
the high-speed (input) seal above the oil level it may not
leak even when the seal has reached the end of it useful
life.

Baldor reducers require no periodic maintenance.
Visual inspection (for oil leakage and general operating
condition) and a simple cleaning to remove dirt build up is
recommended.

GENERAL INSTRUCTIONS
(Oil capacity in fluid ounces RM1 6 oz, RM2 10 oz.
Align all shafts accurately. Improper alignment can result
in failure. Use of flexible coupling is recommended to
compensate for slight misalignment.
Operating Environment
Auxiliary drive components (such as sprockets, gears and
pulleys) should be mounted on the shafts as close as
possible to the housing to minimize effects of overhung
loads. Avoid force fits that might damage bearings or gears.
Gear drives are nameplated for 1750 RPM Input Speed and
Class I Service. For lower Input Speeds and other Service
Classes, consult the factory.
Baldor Ratio Multipliers are designed to

• When using a speed reducer to raise or lower a load, such as in hoisting applications, provision must
be made for external braking. Under no conditions
should a speed reducer be considered self-locking.
Lubrication
In-Line Helical (ILH)
•For safe operation of any gear drive, all rotating shafts and auxiliary components must be shielded to
conform with applicable safety standards. You must
consider overall operational system safety at all times.
For maximum seal life, the Ratio Multiplier should be

to the mounting surface of the “C” flange. (See Drawing B) Tighten setscrews. Key should be flush with
shaft end. Use pipe plug opening in side of “C” flange to loosen, tighten or make any adjustments in
coupling position.
step #4: Align coupling halves and install motor.
step #5: Rotate motor to required position and tighten the supplied four bolts and lockwashers evenly for a solid
fit between motor and “C” flange. Re-install and tighten the pipe plug in the flange access hole.
