Abstract
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.
