Abstract
A comb separator or cage for ball bearings, including a ring that has a collar projecting axially out of one face. A groove extends around the distal face of the collar. The collar is separated into webs by spherical cavities that accommodate the balls. Lubrication ducts extend axially through the ring and the webs and open into the groove. The separator accordingly provides the lubricant with access to the balls from both sides and increases the reserve of lubricant. Preferably the grooves are approximately trapezoidal in their radial cross-section.
