Abstract

Disclosed is a motor bearing which is slidably inserted in the rear housing thereof and which provides automatic end play and positional locking following installation. The section view of the bearing (B) illustrates the general configuration which typically comprises a rigid outer ring and inner bearing, (B1) and (B2) respectively, and an angled flexible membrane surface (B3) in between. The membrane surface (B3) is typically angled at three degrees and always in the direction of insertion with respect to the outer ring. An installation ram (R) pushes the bearing into the cylindrical hole in the motor housing member (M1) of motor (M), first contacting the end of the bearing (B2) to displace it forwardly some small amount before contacting the outer ring (B1).
