Abstract
A method of making a cage whose crossbars ( ) connecting the side rings ( ) are profiled whereby the rolling elements ( ) are retained individually on both sides of the pitch circle by retaining edges ( ) extending parallel to the axis of the rolling elements wherein by an additional shaping by material displacement after the punching out of the pockets ( ), parallel opposing guide surfaces ( ) for the rolling elements ( ) are formed within the pitch circle between the retaining edges ( of the pockets ( ) and the retaining edges ( ) 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 ( ) wherein a defined contact of the rolling elements ( ) with the cage is achieved due to the stamp guide surfaces ( ) so that the mechanical loading of the cage is insignificant.
