Cages for ball bearings are disclosed. In one example, a ball bearing cage includes two side rings interconnected by webs. Rolling element pockets, each of which may have a square basic shape with rounded corners, may be formed in a circumferential direction between the webs. The side rings, together with the webs, may form a guide contour of each rolling element pocket. The pockets may have four convex side contours between the corners thereof, and the side contours may point in a direction opposite to rounded portions in the corners.

Ball bearing cage

An antifriction bearing cage is disclosed including cage pockets that are used for guiding rolling elements, in particular balls, and are formed by two lateral rings having a common axis of symmetry (R) and by webs interconnecting the lateral rings. The lateral rings are designed as single pieces along with the webs and contain a fabric. The fabric is composed of at least two types of different fibers which impart highly anisotropic properties to the fabric.
