Title: Automotive wheel bearing assembly and method for manufacturing the same

Abstract: Reliable wheel bearing assemblies are proposed which need no troublesome runout adjustment at a car assembling factory. There are provided wheel bearing assemblies comprising an outer member having two raceways on an inner circumferential surface thereof, an inner member having raceways each provided opposite the two raceways of the outer member, and rolling elements arranged in two rows between the outer and inner members. One of the outer and inner members is provided with a wheel mounting flange. The runout of the wheel mounting flange is restricted within a predetermined value, and a brake rotor is fixed to one side of the wheel mounting flange. Different methods for minimizing the runout are proposed.
