Developing a Motor Bearing Regreasing Strategy

1. Start by setting a plant wide standard for new motors to
have regreasable bearings. Record the new motors in a lubrication
database with it's location to be included in a lubrication route.
2. Begin with the most recently installed motors and work back
to motors less than 3 years old. Gather information on these motors
to determine if they have sealed or open bearings. Add all motors
with open bearings to the lubrication route.
3. Require regreaseable bearings and grease fittings be installed
in all rebuilt motors from your motor rebuild shop. Add rebuilt
motors to the lubrication route.
4. As motors fail, replace them with motors with regreaseable
bearings and add them to the lubrication route.
5. All critical motors to be monitored on a vibration route.
Motors with sealed bearings or unknown bearings will be replaced
with motors with regreaseable bearings when motor vibration reaches
vibration alarm levels. Eventually all motors will be replaced
and join the motors being regularly lubricated in the database.
