Abstract

The invention pertains to a process and a device for the production of pocket cages for roller bearings. The starting material is a cup-shaped blank or a tube, and the lateral surfaces of the cage are cut at the same time that the rolling element pockets are stamped out. In this way a work step on a separate processing machine is eliminated.
