<p>A composite outer ring for a needle bearing comprising an inner sleeve of hardened thin sheet metal and a non-hardened outer collar which is a tight fit on the sleeve. The collar serves to deform the hardened sleeve so as to rectify any deviation of the shape of the sleeve inner face, which constitutes a raceway, from the desired shape due to distortion of the sleeve subsequent to the hardening of the sleeve. The shape of the outer face of the collar depends on both the desired shape of the raceway and the configuration of the cavity of the part receiving the collar.</p> |
