reducer installation, maintenance and lubrication
Baldor reducers achieve maximum performance
and life when installed properly. Please follow these
instructions carefully.
Baldor reducers filled with Kluber Klubersynth UH16-460 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.
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.
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.
Klubersynth UH1-6-460 is suitable for USDA Class
H1 environments. This synthetic lubrication does not
require periodic changing. The lubrication should
only be replaced when maintenance is performed
that requires disassembly. Use only Klubersynth
UH1-6-460. This lubrication is suitable for a wide
temperature range (-13° to 320° F). However, refer to
“Operating Environment” section for the ambient
operating temperature for Baldor speed reducers.
mounting positions
Because Baldor speed reducers do not require
a breather vent, they are suitable for mounting
in a wide verity of mounting positions without
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 high-speed (input) shaft as high as possible
above the low-speed (output) shaft. Since the highspeed (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 high-speed (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.
operating environment
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.
Accumulation of material on the reducer can lead to
overheating and reduced life.
Baldor Reducers are designed to operate in ambient
temperatures of -10°F to 100°F. The oil sump
temperature of the reducer must not exceed 200°F.
Consult the factory for applications requiring ambient
operating temperature outside this range.
The input horsepower rating shown on the
nameplate of each Baldor speed reducer is the
continuous mechanical rating of 1.0 service factor at
1750 RPM. Before placing the reducer into service,
confirm that its horsepower rating is consistent
with the motor horsepower and desired service
factor. Service factor and speed reducer ratings can
be found in your Baldor Gear Product brochure,
“c” flange – hollow bore worm style:
Step 1. Position key
in reducer worm bore.
Step 2. Apply antiseize compound to
the motor shaft.
Step 4. Install
the four supplied
bolts and lock washers
and tighten bolts evenly for a
solid fit between motor and “C” flange.
Step 3. Line up the
key with the key slot
and slip the motor
shaft in the reducer
worm bore.
extended “c” flange with flexible coupling style:
Step 1. Mount one coupling half on motor shaft so that the coupling half and end of key are flush
with end of motor shaft. (See Drawing A).
Step 2. Tighten coupling setscrews. (Thread locking compound is recommended on all coupling
Step 3. Measure the distance from inner face of coupling to motor mounting surface. (See
Drawing A “L”).
Step 4. Mount other coupling half on the reducer input shaft so the coupling end measures the
same distance “L” to the mounting surface of the “C” flange. (See Drawing B “L”)
Step 5. Tighten setscrews.
Follow the lubrication directions.
