Abstract
The bearing is used in a constant velocity universal joint of the type used in front wheel drive axles for motor vehicles. The universal joint housing has arcuately spaced apart pairs of parallel flat raceways. A bearing is provided in the arcuate space between each pair of housing raceways. The bearing has a single roller which contacts one raceway at a time with a very small clearance from the other raceway. The single roller has a curved outer periphery. A cylindrical sleeve separates the single roller from a plurality of rollers which roll about a bearing support on a shaft which extends into the universal joint housing. The inner cylindrical surface of the sleeve is in contact with the plurality of rollers, each of which have a curved outer surface.
