Outer ring of a wheel bearing

An outer ring of a wheel bearing comprising a hollow cylindrical section and a flange which leads radially outwards from the hollow cylindrical section, the flange merging at a concave channel into the section wherein the channel, as viewed in a longitudinal section through the outer ring along the rotational axis of the outer ring, merges into a face of the flange at a first transition and into a circumferential surface on the section at a second transition, and the perpendicular spacing between an imaginary axial extension of the circumferential surface and the first transition being smaller than a spacing which is parallel to the rotational axis between an imaginary radial extension of the face and the second transition.
