摘要

A full complement needle bearing (100) includes a race (110) and a plurality of rollers (140). The race defines an opening for receiving an associated shaft. The race has first and second radially inwardly directed collars (112,114) on opposing ends of the race to form a channel. The first collar includes a first groove (120) formed along an inner surface of the first collar, and the second collar includes a second groove (118) formed along an inner surface of the second collar. Each of the plurality of rollers has a central portion (142), a first nib (146) extending from one end of the central portion and a second nib (144) extending from an opposing end of the central portion. At least a portion of the first nib is retained within the first groove and at least a portion of the second nib is retained within the second groove so as to retain the rollers parallel to the associated shaft.
