ABSTRACT:
A spherical bearing retainer which is adapted to be readily installed in the bearing hub of a dynamoelectric machine end shield or other suitable bearing support structure by forcing the retainer in an axial direction toward a spherical bearing member to be retained and by simultaneously twisting it within the hub. The retainer has a plurality of tabs engageable with inner surface of the hub with each of these tabs being disposed at a predetermined lead angle relative to the retainer so that upon twisting (or turning) of the retainer in the hub, the tabs "self-thread" the retainer into engagement with its respective bearing member and lock the retainer against movement away from its bearing member.
