The inner diameter surface (47) has an annular groove (46) with its annular center (50) offset from a midpoint (52) of the outer race (42). The assembly (35) also comprises an inner race (37) that is concentric with the outer race (42). The inner race (37) has an outer diameter surface (45), an exterior end (39), and an interior end (43). The outer diameter surface (45) has a second annular groove (44) with its annular center (50) offset from a midpoint (52) of the inner race (37). The second annular groove (44) of the inner race (37) is aligned with the annular groove (46) of the outer race (42) and a plurality of bearings (40) are disposed therebetween. A bearing retaining cage (54) is provided at the interior ends (41,43) of the races (37,40) to retain the bearings (40) in a spaced apart relationship. A sealing cap (55) is provided between the inner (37) and outer (42) races at the exterior ends (39,38) of the races (37,42).
