The Ball Bearing Rings are offered by us that consists of an inner ring (IR), an outer ring (OR), a complement of balls, and a separator to contain the balls. The outer diameter of the inner ring (IROD) and the inner diameter of the outer ring (ORID) have a groove in which the balls roll on. Also called tolerance rings,these rings are for use in stamped, molded, or worn housings to form a tight hold on the bearings. Ball bearings are types of rolling-elements bearings that carry loads, reduce friction, and position moving machine parts while facilitating motion. Ball Bearing Rings are very effective.
