Abstract

A radial cage in which roll forming is carried out in such a manner that straight side sections of all axial crossbars continue to have at least approximately a material thickness of a starting material for the radial cage, while side rings of the radial cage and axial center sections of the axial crossbars are implemented by rolling down during roll forming to each have material thicknesses that are smaller than the material thickness of the straight side sections and that reduce their centrifugal mass.
