Abstract

A ball bearing for longitudinal movement on a shaft or the like, comprising a cage which at least partially surrounds the shaft and is installed in the bore of a housing, ball guides consisting of axial guide tracks for the loaded and unloaded balls arranged next to each other around the periphery with semi-circular deflector tracks joining pairs of these guide tracks, endless rows of balls guided in the guide tracks, and at least one raceway element supported in the bore of the housing carrying the loaded balls of one or more guide tracks on its radially inwardly directed raceway, a longitudinal fillet projecting radially from the inside and toward the outside approximately as far as the height of the centers of the balls between two guide tracks of each ball guide and formed on the cage in such a way that the radius of curvature of each ball guide passing through the centers of the balls of the deflector tracks is equal to or slightly larger than half the diameter of the balls.
