Bearing Set Screw Alignment
Fan Bearing Lubrication
NOTICE:
Bearing Failure!
Do not mix greases with different bases within the bearing. Mixing grease within the bearing
could 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 35
for compatible greases and
Table 36
for
maximum grease capacity.
Note:
Lubricate the bearing according to the motor manufacturer’s recommendations 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.
