Abstract
A ball bearing for linear movement on a shaft has a cage with oval guideways, and an outer sleeve surrounding the case. The cage has axially extending raceways for guiding loaded balls, the ends of the raceways joining radially outwardly directed transitions. The transitions are weakened by transversely extending grooves or slots, to provide resilience. The raceways may be axially extending radially inwardly directed ridges having central axially extending grooves, and the transitions may have V-shaped recesses with their apices at the ends of the grooves, to define two-point contact with the balls in the transition area of the bearing. A split sleeve may surround the outer sleeve for additional support.
