Abstract
The aim is to make unnecessary secondary turning of a hub ring of a wheel bearing assembly by improving the run-out accuracy of a wheel-mounting flange and the coaxiality of the brake pilot portion. With the brake pilot portion of the wheel-mounting flange clamped and with a backing plate in abutment with an outer peripheral portion of the wheel-mounting flange, by axially biasing an end face of the small-diameter portion of the hub ring with a pressure clamp, at least the bearing raceway of the hub ring is ground with the outer side face of the wheel-mounting flange as a reference surface.
