摘要： A wheel bearing unit is provided in which the service life level is improved without making the size and weight of the bearing unduly large. The wheel bearing unit for rotatably supporting a car wheel on the body of a motor vehicle comprises a rotary member, an outer ring, and double rows of rolling elements. The rotary member comprises a hub wheel to which a car wheel is attached and an inner ring press-fitted to the outer circumference of the smaller end face of the hub wheel, wherein double rows of raceway surfaces are formed in the outer circumferential surfaces of the hub wheel and the inner ring, respectively. The outer ring has double rows of raceway surfaces formed therein so as to be opposite to the raceway surfaces of the hub wheel and the inner ring, and is fixedly coupled to a car-body-side knuckle. The double rows of rolling elements are interposed between the raceway surfaces of the hub wheel, the inner ring, and the outer ring. In this construction, at least the hub wheel and the inner ring are each made of a carbon steel containing 0.60 to 0.80 wt % of carbon, and a surface hardened layer is formed in the predetermined area thereof by a high-frequency quenching technique.

摘要： The end surface 2e of the press-fit portion 2c of the axle 2 is machined with high precision to serve as a reference surface for measuring the negative bearing clearance upon completion of the assembly. The inner ring 3 is press-fitted on the press-fit portion 2c of the axle 2 and is fixed in position by the nut 6 screwed on the threaded portion 2d of the axle 2. In this axle bearing assembly, the inner ring 3 abuts against the shoulder portion 2d of the axle 2 with no clearance defined therebetween, and the negative bearing clearance is assured.
