Patent ID: 8702315

Claim:
A radial cage for cylindrical rolling elements, comprising: two side rings disposed at axial ends along an axial direction of the radial cage; and a plurality of profiled axial crossbars that connect one of said side rings to the other side ring at their outer diameters, forming a plurality of pockets for accommodating the cylindrical rolling elements between the crossbars, each of the axial crossbars comprising: two axially straight side sections connected to the side rings, two intermediate sections extending at an angle to the axial direction of the radial cage, and an axial center section, the side rings having a first material thickness, S 1 , in the axial direction, the straight side sections of each axial crossbar have a second material thickness, S 2 , in a radial direction, and the axial center section of each axial crossbar has a third material thickness, S 3 , in the radial direction, wherein S 2 >S 1 and S 3 <S 1 , the intermediate section of each axial crossbar is uniformly tapered between the material thickness S 2 of each respective side section and the material thickness S 3 of the respective center section, bottom edges of the axially straight side sections include angled stop faces, and each cylindrical rolling element is radially retained in the radial cage by the angled stop faces of the axially straight side sections and top edges of the center section of a respective axial crossbar, without being radially retained by the intermediate sections of the respective axial crossbar.
