ABSTRACT:
A ball bearing retainer in the form of a unitary molded plastic ring has a central axis with an inner peripheral edge and an outer peripheral edge spaced about the axis. A base portion of the retainer ring extends between the inner and outer peripheral edges, and a plurality of ball bearing receiving pockets open axially of the retainer ring in a direction opposite from the base portion. Each pocket has a generally truncated spherical concave seat for retaining a ball bearing within the pocket. Each pocket has at least one generally cylindrical surface extending radially from one of the peripheral edges to intersect with the generally truncated spherical concave seat and thereby relieve the truncated spherical portion of the pocket adjacent the peripheral edge from which the cylindrical surface extends.
