ABSTRACT:
An axially elongated ball bushing is inserted into a bore in a housing. The ball bushing includes an axially elongated cage having a plurality of ball loops each extending in the axial direction of the cage and containing a number of balls located in a loaded ball duct and an unloaded ball duct of the loop. Each loaded ball duct is open through the radially inner and outer surfaces of the cage. The ducts of the loops are arranged so that, in each loop, its loaded ball duct is adjacent the loaded ball duct in one adjacent loop and its unloaded ball duct is adjacent the unloaded ball duct in the other adjacent loop. A joint race insert formed of a thin hardened sheet steel bridges each pair of adjacent loaded ball ducts and the race portions of the inserts are bent radially outwardly against the surface of the bore by the loaded balls, however, the inserts do not yield in the thickness direction.
