A rolling element bearing, in particular a roller/needle bearing, having a cage including at least one inner cage and at least one outer supporting cage, said cages having windows () which are adapted to the rolling elements () and have lateral end rims () connecting a plurality of windows () and crossbars and in which the rolling elements () are guided and secured from falling out. Either the inner cage and the supporting cage are configured as a split inner cage ring and/or a split supporting cage ring and the rings can be attached to each other at the ends or the inner cage and the supporting cage are configured as inner cage shells and/or supporting cage shells and the shells can be attached to each other at the ends.

Rolling element bearing comprising a multi-part cage

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.

Radial cage for cylindrical roller bodies

A radial cage in which side rings have a material thickness of a starting material for the radial cage, straight side sections of each axial crossbar are implemented with a greater material thickness that increases their strength, and an axial center section of each axial crossbar is implemented with a smaller material thickness than the material thickness of the side rings, thus reducing centrifugal mass.
