Abstract

The invention relates to a wheel bearing unit (1) for a vehicle wheel, comprising a hub element (2, 3, 2′) which has an axially (a) extending cylindrical section (4) to be supported by a bearing arrangement (5) and which has a radially (r) extending flange section (6) for fixing the vehicle wheel and/or a brake disk at a face side (7) of the flange section (6), wherein the bearing arrangement (5) has an outer ring (8). To ensure a firm and cost effective axial connection between the hub element and the outer ring, the invention is characterized in that the outer ring (8) has a radially extending insection (9) at its a outer circumference (10), wherein the axially (a) extending cylindrical section (4) of the hub element (2, 3, 2′) is deformed partially (11) so that a section of it interferes in the insection (9) for axially fixing the hub element (2, 3, 2′) relatively to the outer ring (8). The invention also relates to a method for producing a wheel bearing unit.
