Abstract:
1. A flanged bearing ring for a motor vehicle wheel, the ring including a first hardened material and a second material, wherein the first material and the second material are two different materials joined together as a single piece, the ring comprising: a radially inner tubular or annular core which forms at least one raceway around a central axis of rotation, the core providing a radially outer surface, an axially extending inner cavity and being made of the first hardened material; a radially outer body which is formed around said outer surface of the core defining with this surface an interface surface, forms a radially outwardly extending flange around the core, and is made of the second material, wherein the second material is softer than the first hardened material; and an element of generally tubular shape, which contacts both the outer body and the inner core so as to cover and seal with continuity, along an entire circumference around the axis, a circular line of separation at the end of the interface surface between the core and the outer body at the axially outer side of the ring, forms a cylindrical axial edge which extends in an axially inner direction and is fixed in the axially outer end of the cavity of the core, and also forms a cylindrical tubular portion projecting axially beyond the radially outwardly extending flange for centring the vehicle wheel.
