Claim Text:
1. An axial cage for cylindrical rolling bodies, comprising a thin-walled washer with a W-shaped profile, individual profile legs of which are formed by an inner radial rim formed on an inner edge of the washer, an outer radial rim formed on an outer edge of the washer and a U-shaped center crimp connected by way of inner and outer axial profile sections to the inner and outer radial rims and having a same radial extent as the inner and outer radial rims, a number of evenly spaced rectangular cage pockets are cut from the center crimp and adjacent ones of the axial profile sections, between said pockets an equal number of pocket connecting pieces are formed connecting the inner and outer radial rims with one another, said connecting pieces acting to retain the cylindrical rolling bodies in the cage pockets at uniform distances from one another and to guide the cylindrical rolling bodies in a circumferential direction, the outer radial rim is formed with an inclination angle (α) facing away from the U-shaped center crimp and the cage pockets have an axial length greater than a smallest axial distance between inner sides of the inner and the outer radial rims such that the cage pockets extend at least into the outer radial rim of the axial cage and, outer end faces of the cage pockets have a crowned formation extending towards a center of the pocket on the outer radial rim of the axial cage at a height of the rolling axes of the rolling bodies that form rounded thrust lugs for respective outer end faces of the rolling bodies.
