1,168,652. Bearings. TORRINGTON CO. 24 Oct., 1966 [24 Oct., 1965], No. 47558/66. Heading F2A. A roller cage comprises axial circumferentially spaced elements 13 of generally U-shaped crosssection, the limbs 15 of the U having end faces 16 for retainer rollers. In Fig. 3, elements 13 are connected by tabs 12 to an annular rim 11. The cage is formed from a disc of sheet metal by forming a ring of I-shaped openings (18, Fig. 2, not shown), removing the centre of the disc by piercing, and using a forming member to orientate elements 13. The cage is positioned in an outer race (21, Fig. 4, not shown) of U- shaped cross-section, the rollers being inserted into the race with the cage before the second limb of the race is bent over, or the rollers are snapped into the assembled cage. The limbs 15 of the elements 13 extend radially with respect to the axis of the abutting roller. The cage may be used in the bearings of an overrunning clutch.
