Flanged Bearing Ring for a Motor Vehicle Wheel Bearing Unit

A flanged bearing ring for a motor vehicle wheel, the ring comprising:

• a radially inner, generally annular insert formed of a first material with a first thermal expansion coefficient, the insert having a central axis, at least one raceway extending about the axis, a radially outer surface, and at least one recess extending generally radially inwardly from the outer surface;
• and
• a radially outer body formed of a second material with a second thermal expansion coefficient, the second coefficient being greater than the first coefficient, the outer body being disposed about the insert and having a radially outwardly extending flange and at least one radially inwardly extending projection disposed within the recess of the insert so as to interlock and prevent relative axial displacement between the insert and the outer body.
