摘要： The invention relates to an axial cage for cylindrical rolling elements, which is formed substantially of a thin-walled annular disc with a profiled cross section, which is formed by an inner radial rim shaped on the inner edge of the annular disc, by an outer radial rim shaped on the outer edge of the annular disc, and by a center beading connected to the radial rims via axial inner and outer intermediate profile sections. A number of uniformly spaced, rectangular cage pockets are removed from the beading and the adjacent intermediate profile sections, between which cage pockets an identical number of pocket webs are formed connecting the rims with each other, by which the cylindrical rolling elements are held in the cage pockets at a uniform distance to each other and guided in the circumferential direction. The annular disc according to the invention is formed of a through-hardened and tempered, high-alloy spring steel with a maximum hardness of 450 HV, wherein any conventional spring steel with a minimum material thickness of 15% to 25% of the diameter of the rolling elements can be used as the spring steel for the annular disc.
