Abstract: 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.

Abstract: 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.
