These instructions must be read thoroughly
before installing or operating speed reducers.
File instructions for future reference.
• 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.
• 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.
• Mounting of speed reducers in overhead positions
may be hazardous.Use of external guides or
supports is strongly recommended for overhead
mounting.
GENERAL INSTRUCTIONS
Align all shafts accurately. Improper alignment can
result in failure. Use of flexible coupling is
recommended to compensate for slight
misalignment.
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.
INSTALLATION
Baldor Ratio Multipliers are ready for installation as
removed from the carton. They incorporate an
internal expansion chamber (Bladder), which
eliminates the traditional requirement for a breather.
Each Ratio Multiplier has been filled with mobil
SHC634 Synthetic lubricant at the factory, the oil
quality is sufficient for any mounting position.
LUBRICATION
Oil changes are not required. Oil should only
be replaced when maintenance is preformed
that requires disassembly. If the oil is
replaced, use Mobil SHC634.
MOUNTING POSITION
For maximum seal life, the Ratio Multiplier
should be mounted with the input shaft as
high as possible. Mounting the Ratio
Multiplier with the input seal vertically down
is not recommended. If a vertically down
input shaft position is required, consult the
factory.
A packet of Fel-Pro C5-A Anti-Seize Lubricant is
supplied with the Ratio Multiplier. Lubricate the
motor shaft and key with the anti-seize lubricant
before installing the motor onto the Ratio
Multiplier. (Oil capacity in fluid ounces RM1 4 oz,
RM2 8 oz.
OPERATING ENVIRONMENT
Baldor Ratio Multipliers are designed to
operate in ambient temperatures of -10°F to
100°F. The oil sump temperatures of the
Ratio Multiplier must not exceed 200°F.
Consult the factory for applications
requiring ambient operating temperature
outside this range.
Satisfactory performance may be obtained with
non-synthetic oils and will require more frequent
changes.
