Abstract

1440459 Bearings SKF NOVA AB 13 Sept 1973 [15 Sept 1972] 43124/73 Heading F2A A ball bushing comprises a sleeve 1, a shaft 4, and recirculating balls arranged therebetween and guided in a cage 3, the sleeve having a number of load-supporting ridges 7 extending from its outer surface and the interior of the sleeve being of polygon shape, each polygon surface being provided in the middle thereof with a recess 8 for the reception of a load-carrying strip 5 for balls in the loaded zone, said strips also centering the cage, which is of polygon shape corresponding to that of the interior of the sleeve. The cage is retained axially by bentover portions on the ends of the sleeve. The sleeve is extruded from aluminium, the strips 5 are of steel, and the cage is of plastics. The contact surfaces of the strips may be grooved as shown, or planar.
