A form-coupling arrangement in a bearing ring for a motor vehicle wheel

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), having two axially opposite sides: - a first side, subjected to a turning finishing process, which provides an undercut surface (23) defining part of an annular groove (22); and - a second side, not subjected to a turning finishing process, which 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).
