ABSTRACT:
An antifriction bearing cage comprises two plastic pieces which are snap assembled. One cage piece comprises a ring portion and a plurality of circumferentially spaced axial fingers having shank portions at the free ends. The shank portions have radial projections which are aligned with axial grooves extending through the finger portions and ring portion to facilitate molding of the first cage piece in an axial draw mold. The second cage piece merely consists of a ring portion having a plurality of spaced holes having radial enlargements at one end extending to the end surface of the ring portion to facilitate molding of the second cage piece in an axial draw mold. During assembly the radial projections of the one cage piece are snapped into the radial enlargements of the other cage piece to retain the cage pieces together.
