ABSTRACT:
A ball bearing cage for retaining and separating bearing balls includes a series of circumferentially spaced, spherical ball retention pockets terminating in opposed flexible retention lips located in a common radial plane of the body portion of the cage. The cage includes a ball separation and guidance projection between each ball retention pocket. The projection includes a pair of sloped walls extending from an apex axially beyond the plane of the retention lips and integral with a retention lip. Each projection further includes a radial opening intermediate the sloped walls and the body of the cage. During bearing assembly, a complement of bearing balls are separated and guided by the sloped walls toward respective retention pockets, the sloped walls and projections flexing toward one another about the apex as the retention lips of adjacent ball pockets are flexed apart by the bearing balls snap fitting within the pockets.
