The two sets of bearing balls, held in respective cages, are also received in a pair of closely spaced peripheral grooves of the shaft confronting the tracks of the sleeve, thereby preventing relative axial shifting of the sleeve and the shaft. A set of bearing rollers are inserted between smooth surface portions of the shaft and the sleeve near the opposite end of the latter and are lodged in pockets of an annular cage having a peripheral rib snap-fitted into the retaining groove. | |
