CAUTION
Bearing Failure!
Do not mix greases with different bases within the bearing. Mixing grease within the
bearing may result in premature bearing failure.
The grease used in electric motor bearings is usually not compatible with the grease used
in fan bearings. Never mix the two grease types! See Table 15 for compatible greases and
Table 16 for maximum grease capacity.
Note: Lubricate the bearing according to the motor manufacturer's recommendations
Refer to Table 17 for minimum torque of motor mounting and bearings bolts.

and use the manufacturer-recommended grease.
Fan bearings without lubrication lines are sealed bearings. Re-lubrication is not
required.
Fan bearings equipped with lubrication lines should be lubricated with a lithium-
based grease that conforms to NLGI No. 2 for consistency.
Align bearing set screws as illustrated in
