Abstract

A bearing cage having two rings connected by webs for angular contact two-row ball bearings where the bearing cage ring has cage pockets of a partial spherical shape. The radial plane of the bearing passes through the centers of the partial spheres and is placed off-center with respect to the bearing cage ring faces, the distance between the radial plane and the face less distant from the radial plane being preferably equal to the radius of the ball.
