MOTOR LUBRICATION
- Long time satisfactory operation of an electric motor depends in large measure
on proper lubrication of the bearings. The following charts show recommended grease qualities and
regreasing intervals for ball bearing motors. For additional information, refer to the motor manufacturer’s
instructions.
The following procedure should be used in regreasing:
1. Stop the unit.
2. Disconnect, lockout and tagout the unit from the power supply.
3. Remove the relief plug and free hole of hardened grease.
4. Wipe lubrication fitting clean and add grease with a hand-operated grease gun.
5. Leave the relief plug temporarily off. Reconnect unit and run for about 20 minutes to expel the
excess grease.
6. Stop the unit. Replace the relief plug.
7. Restart the unit.
WARNING
Rotating machinery can cause injury or death. Open main disconnect, lockout
and tagout power supply to starter before working on the electric motor.
