A flanged bearing ring is made up of two different materials joined together as a single piece, namely a radially inner annular insert and a flanged, radially outer lightweight body formed around the insert. The insert forms one or more raceways and is made of a hard material, such as bearing steel. The outer body is made of a lightweight material, such as aluminium alloy, with a higher thermal expansion coefficient higher than that of the hard material which the inner insert is made of. A relief formed by the insert extends into a groove of the outer body. Another relief, formed by the outer body, extends into a further groove of the insert. These reliefs and grooves interlock the insert and the outer body together against relative movement under all temperature conditions.
