Bearing Maintenance
One of the most important features in the
successful operation of an induction motor are the
bearings.
The machines covered by these instructions are
supplied with anti-friction bearings.
A conscientiously applied program of preventive
maintenance will add years of useful life to the bearings.
In order to assure proper operating conditions, see
section entitled Grease Recommendation.
Bearing Repair and Replacement
Even though high-quality design and workman-
ship are incorporated in a bearing, it sometimes becomes
necessary to remove if for maintenance. It is for this
reason that the following instructions are included.
Care must be taken to avoid scratching or nicking
the critical surfaces of the balls or rollers.
Bearing Disassembly
Extreme care is required in the disassembly of a
machine for bearing removal. In addition, the surfaces of
the shaft bearing fit and the bearing itself must be
protected during and after disassembly operations.
