Abstract
A bearing ring () has a tubular steel core () around which is formed an outer body () of lightweight material. The outer surface of the core forms a circumferential shoulder (), a first side of which is subjected to a turning finishing process and provides an undercut surface () defining part of an annular groove (). An axially opposite, second side of the shoulder (), not subjected to a turning finishing process, has a non-circular portion () with radial recesses () that act as anti-rotation means cooperating with complementary portions formed by the outer body ().
