Abstract

A rolling bearing for longitudinal movement has a cage with its inner surface surrounding a shaft. The cage has axially extending races for loaded balls and axially extending return races for unloaded balls, as well as a cover on each of its two ends. Each cover has turn around races connected between the ends of a race and a return race. The races, return races and turn around races have slits extending along the races and open to the shaft. Each turn around race in the covers is bounded by a curved shoulder section on the inner surface of the cage and extending along the turn around race, and a curved inner wall section of the cover extending parallel to the curved shoulder wall section of the cage.
