Abstract
A wheel bearing unit for example for use in a motor vehicle, including an antifriction bearing clamped on the hub. The hub includes a bore which defines a tubular hub part that prior to deformation extends past the axially outer end of the inner ring of the bearing. The tubular hub part is deformed radially outward around the radially inner, axially outer edge of the inner ring to clamp the inner ring and the bearing to the hub. Features of the inner ring and hub for enabling such clamping are disclosed including the hub material hardness, the hub having a tubular part of a particular wall thickness and a length protruding beyond the axial end of the bearing, the radius of the edge of the inner ring about which the bead is formed, the thickness of the bead and its angle of inclination both with reference to the end of the inner ring and to the interior bore, and the depth of the bore.
