REPLACEMENT BEARINGS
Your maintenance program will not be complete without
including spare bearings. It must be remembered that
the bearing is a wearable component and therefore
must eventually be replaced. To insure that you are
able to maintain original operation, we recommend the
purchase of spares directly from Reliance Electric.
All bearings used in Reliance motors are subject to
exact specifications and tests necessary to satisfy per-
formance requirements. In this manner, it is possible to
duplicate your present bearing. Markings on the bear-
ings do not indicate complete specifications.
