Conical needle bearing for conveyor rollers - has cold-stamped inner and outer race, providing double-taper internal bore

摘要

The needle bearing consists of an inner and outer race (1,2) with the needle rollers (3) running in the tracks (5,6) between them. The needle rollers follow a conical path. They are retained by a cage (4). The bore (7) of the inner race has a tapered lead at either end (8,9). The parallel bore (7) is offset so as to take the load from the conical needle bearings. The tapered leads compensate for any slight misalignment during assembly. The races are formed by cold stamping.
