Roller bearing e.g. tapered roller bearing, has inner and outer bearing rings designed as multiple closed hollow sections, which comprise short pipe sections that are bent and connected together at abutting ends

摘要

The bearing (1) has an inner bearing ring (2) and an outer bearing ring (3) designed as multiple closed hollow sections, which comprise short pipe sections (15) that are bent and connected together at abutting ends. The inner and outer bearing rings obtain a final shape by non-cutting shaping process. Tracks (4, 5) for rolling elements (6) i.e. cylindrical rollers, are formed between the inner and outer bearing rings. The pipe sections are made of different materials, and have different wall thicknesses and different cross-sectional profiles.
