Wheel bearing unit with mounting openings for the brake caliper carrier

A wheel bearing unit comprising:

• a bearing including an outer bearing race and an inner bearing race rotatable with respect to the outer race;
• a first flange connected to the inner bearing race that is configured for attachment thereto of a brake disk and a wheel;
• a plurality of first mounting openings in the outer bearing race that are configured to permit attachment of a brake caliper assembly to the outer race;
• and
• a plurality of second mounting openings in the outer bearing race that are configured to permit attachment of the outer race to a wheel carrier, wherein:
• the first and second mounting openings are arranged relative to an axis of symmetry extending across the outer bearing race such that the wheel bearing assembly is mountable on the left and right sides of a vehicle with a brake caliper assemblies in the same relative position on both sides,
• the second mounting openings are located at a first radial distance relative to the rotational axis of the bearing such that the second mounting openings overlie a region of high strength on the wheel carrier;
• and
• the first mounting openings are located at a second radial distance relative to the rotational axis of the bearing which is sufficiently greater that the first radial distance that the first mounting openings are clear of the region of high strength on the wheel carrier.
