Abstract

A method of making a cage whose crossbars (3) connecting the side rings (1,2) are profiled whereby the rolling elements (5) are retained individually on both sides of the pitch circle by retaining edges (12,13) extending parallel to the axis of the rolling elements wherein by an additional shaping by material displacement after the punching out of the pockets (4), parallel opposing guide surfaces (11) for the rolling elements (5) are formed within the pitch circle between the retaining edges (12,13of the pockets (4) and the retaining edges (12,13) on both sides of the pitch circle are dimensioned so that the distance between them in the peripheral direction is only slightly smaller than the diameter of the rolling elements (5) wherein a defined contact of the rolling elements (5) with the cage is achieved due to the stamp guide surfaces (11) so that the mechanical loading of the cage is insignificant.
