ABSTRACT:
A cage for a roller bearing which is free of fretting and abnormal noise, which can be manufactured at low cost, and which can be easily mounted in the bearing. The cage is formed by bending a metal sheet having pockets into a ring shape, temporarily joining its ends, heat-treating the ring thus formed to remove stress, and separating the temporarily joined portion. Such a cage tends to rotate slower than the raceway members on the driving side of the bearing, making it possible to reduce fretting. Such a cage can be used under high-temperature conditions.
