Abstract
The outer ring of the support roller mounted on an anti-friction bearing of a rolling mill has a soft core that is case hardened on its inner bore surface and on its outer peripheral surface, while not being case hardened at its axial end face sides, so that the outer ring will retain a cylindrical shape both for the inner bore surface, which rides on the rollers of the bearing, and the outer peripheral surface which supports the roll in a rolling mill.
