ABSTRACT:
An inner ring is shaped in its contour by a cold-shaping treatment and is hardened on its surface by a nitrosulphurizing treatment or a soft-nitriding treatment. As a result, the hardness of the surface of the inner ring is enhanced by the cold-shaping treatment and further by the subsequent hardening treatment. As a result, the inner ring is improved in its wear resistance and its seizure resistance. Moreover, the hardening treatment is effected by the nitrosulphurizing treatment or the soft-nitriding treatment so that it can be suppressed from straining in that treating procedure.
