Abstract

A bearing ring (10) has a tubular steel core (15) around which is formed an outer body (16) of lightweight material. The outer surface of the core forms a circumferential shoulder (26), a first side of which is subjected to a turning finishing process and provides an undercut surface (23) defining part of an annular groove (22). An axially opposite, second side of the shoulder (26), not subjected to a turning finishing process, has a non-circular portion (29) with radial recesses (28) that act as anti-rotation means cooperating with complementary portions formed by the outer body (16).
