    摘要： A wheel support bearing assembly, which enables an increase in the strength and the fatigue strength of its wheel mounting flange or vehicle body fitting flange against high stress and repeated stress and the suppression of the increase of the number of processes, includes an inner member and an outer member rotatable relative to each other through rolling elements. The flange is formed on the inner member or the outer member, for example, a hub. A component part having the flange is a hot-forged product of steel in which a matrix portion is formed as a standard structure and the non-standard structural portion is formed on the surface of the flange. The non-standard structure is formed of either of a fine ferrite/pearlite structure, an upper bainite structure, a lower bainite structure, and a tempered martensite structure, or mixture of two or more of these structures.

    摘要： A vehicle wheel bearing apparatus has an outer member with a body mounting flange, an inner member and double row rolling elements freely rollably contained between the inner and outer raceway surfaces of the inner and outer members. The body mounting flange is formed with a plurality of screw apertures. An inner side flange surface of the body mounting flange is formed by machining to have a flat vertical surface relative to a longitudinal axis of a wheel hub. An outer side flange surface of the body mounting flange is formed by forging to have a tapered surface of a predetermined inclined angle. Thus, the thickness of the body mounting flange is gradually reduced radially outward.

    摘要： A vehicle wheel bearing apparatus has an outer member, an inner member, and double row rolling elements freely rollably contained between the inner and outer raceway surfaces of the inner and outer members. A brake pilot portion extends from a base of a wheel hub mounting flange toward the outer side to guide an inner circumferential surface of a brake rotor. A wheel pilot portion extends from the brake pilot portion further toward the outer side to guide an inner circumferential surface of the wheel. The wheel pilot portion including a plurality of separated pilots separated along a circumferential direction. A chamfered portion is formed, by forging, on a forward end of each separated pilot in view of its lathe cutting direction. The chamfered portion has a predetermined inclined angle relative to an axial end surface of each separated pilot after lathe cutting.

    摘要： A bearing device for a wheel enabling the easy control of quality since there is no possibility of cracking even if caulking is applied thereto. The bearing device comprises an outer ring having double rows of raceway surfaces on the inner periphery thereof, an inner member having raceway surfaces opposed to the raceway surfaces, and balls interposed between the double rows of raceway surfaces opposed to each other. The inner member further comprises a HUB ring and an inner ring. Caulking is applied to the HUB ring to join it to the inner ring. The grain size number of the austenite grains of a caulked section is at least 6.
