Combined roller and ball bearing with inner and outer races - is of thin race type with rollers and balls of same dia. and on same race tracks

摘要

The device is a roller bearing of a thin overall cross-section. It comprises an outer race (2), an inner ring (3), separated by rollers (6). The rollers are positioned via a cage (4) and run within tracks (7) in the inner and outer rings. The cage incorporates holes for ball bearings (10) which run on the same surfaces as the roller bearings. The cage is produced by stamping from sheet metal. USE/ADVANTAGE - The combination of ball and roller bearings allows the production of a thin section bearing with high axial and radial load bearing properties. The design also provides a simple method of retaining the cage in the bearing.
