Abstract

A two-piece rolling bearing cage with cage bridges provided on at least one cage section. The bridges engage in corresponding recesses of the other cage section and connect the two cage sections together. The invention comprises a snap pin at the free end of each cage bridge, each snap pin having a broadened head section and an undercut surface. Each of the recesses accommodates a snap pin which has a corresponding contact surface for mating with the undercut surface. The head section has a front recess means and each recess has a preferably conical projection which, after assembly of the cage sections engages the front recess means of the head section.
