Abstract

A cage for a rolling bearing has spreadable holding projections defining pockets for receiving rolling elements. In order to inhibit separation of the rolling elements from the cage after insertion of the rolling elements between the holding projections, the cage has deformable or spreadable cage portions positioned to be spreadable or deformed after insertion of the rolling elements in the cage, for supporting the adjacent holding projections against movement away from the adjacent rolling elements.
