AW-2
Appendix W2 Maintenance of Motor Bearings
(continued)
If the motors are out of use for a longer period of time, the mo-
tor shaft should be rotated once a month. Rotate the motor
shaft manually for at least 5 rotations and bring to a stop in a
different position to the starting position.
If the motors are out of use for more than 6 months, the motor
bearings must be re-lubricated before start-up.
If the motors are out of use for more than 2 years, the motor
bearings must be replaced.
Here are the details of the bearings installed. The lubrication
quantities to be filled (only for WEG motors) are listed below:
