Patent ID: 8914965

Claim:
A processing method for cutting the pad slide surface of the brake rotor of a brake rotor-equipped wheel bearing device which comprises an outer member having a car body attaching flange in the outer periphery and two rows of raceways in the inner periphery, an inner member consisting of a hub ring having a wheel attaching flange in the outer periphery and an inner ring disposed in the small diameter section of the hub ring, two rows of rolling elements interposed between the raceways of the outer and inner members for relatively rotatably supporting the two members, and a brake rotor fixed to the wheel attaching flange of the hub ring, said processing method comprising the steps of lathing, with the hub ring present singly, the wheel pilot end surface of the hub ring with the reference provided by the raceway of the hub ring, assembling the outer and inner members and the rolling elements together, fixing the brake rotor to the hub ring of the inner member, and lathing the pad slide surfaces of the brake rotor with the reference provided by the pilot wheel end surface of the hub ring.
