Abstract:
1. A cage for a roller bearing having a bearing axis extending in an axial direction, the cage including: at least two crosspieces which extend between two axially spaced edges and are spaced from one another in a circumferential direction oriented perpendicular to the axial direction so that a rolling element can be disposed between them, wherein at least one crosspiece of the at least two crosspieces has a first radially inner surface region that is a constant radial distance from the bearing axis, and first and second side surfaces extending from the first and second circumferentially spaced sides of the first radially inner surface region toward an exterior of the cage, and wherein the at least one crosspiece has a second surface region which is adjacent to the first surface region and comprises a step along which the radial distance from the bearing axis varies.
