Abstract
A separator for a ball bearing includes an annular body having a centerline, opposing first and second axial ends and an inner circumferential surface defining a central pocket sized to receive one of the plurality of balls. Preferably, the annular body has a concave outer circumferential surface defining an annular channel and configured to contact at least one adjacent one of the balls along a curved line extending at least partially between the first and second axial ends or at a plurality of contact sections spaced axially apart. The outer circumferential surface has a radius of curvature about equal to a radius of curvature of an outer surface of each one of the balls. Further, the annular body preferably also includes a plurality of annular grooves spaced axially apart, each annular groove extending radially inwardly from the concave outer circumferential surface and circumferentially about the centerline.
