Abstract

A cage for roller bearings made of a plastic material consisting of two annular side parts and a plurality of circumferentially spaced crosspieces joining the side parts to form pockets for the rolling elements, said pockets including elastically deformable retaining projections for guiding said rolling elements and retaining them in the cage, said side parts having a U-shaped cross-section with axially outwardly directed shanks and said crosspieces consisting of two thin-walled, curved parts which are arranged around the periphery at a predetermined distance from one another, the outer surfaces of these parts being arranged to face each other.
