<p>Novel thin walled cylindrical antifriction bearing cages comprising end rings connected by a plurality of crossbars forming roller pockets therein formed from a flat strip, one end ring being wider than the other end ring and provided in the area of the abutting edges of the cylindrical strip with at least one recess so that at least one juxtaposed surface remains for welding whose material cross-section is substantially the same as the cross-section of the narrower end ring available for welding.</p> |
