A cast bushing, a hub, a bearing seat or the like for mounting on a cylindrical shaft (1) is reinforced by means of a helix (2), e.g. made from steel, and is characterized in that it is prevented from rotation relative to the shaft (1) by the casting material (3) radially inside the helix (2) having axially extending depressions or ridges (5,6,7) in the cylindrical surface for co-operation with corresponding ridges or depressions in the surface of the shaft (1). |
