Abstract

A prong-type cage for rolling bearings formed by a ring and circumferentially spaced prongs or posts extending axially from the ring, defining pockets for separating the rolling elements, is designed to avoid being damaged when the mold parts are removed by recesses axially extending from the outer face of the ring axially into the posts.
