Abstract
In a cage for cylindrical rolling bearings ( ), which cage is rolled out of a sheet metal strip ( ), the pockets ( ), as seen in a top view, have, in a profiled, punched and unbent state of the sheet metal strip ( ), a curved shape in a region of the inclined sections ( ), so that an axially inner, first convex curve B merges into an outer, second concave curve B This pocket contour of the invention makes it possible to obtain a separation between the retention of the rolling elements and the contact region of the rolling elements in the cage solely by the punching of the pockets in combination with a subsequent bending of the cage strip into a finished cage.
