    • A vehicle wheel bearing apparatus has an outer member, an inner member with at least one inner ring, double row rolling elements, and a constant velocity universal joint torque transmittably inserted into a wheel hub and axially separably connected by a securing nut. A shoulder of an outer joint member of the constant velocity universal joint abuts against a larger end face of the inner ring. The larger end face of the inner ring is formed as a ground surface. An end face of the shoulder of the outer joint member abutted against the larger end face is formed as a ground surface or a lathe-turned surface. The surface roughness Ra of at least the larger end face of the inner ring is limited to a range within 0.1˜0.3.
    • 车轮轴承装置具有外部构件,具有至少一个内圈的内部构件,双列滚动元件和可传递地插入到轮毂中的等速万向接头扭矩,并且通过固定螺母轴向可分离地连接。 等速万向接头的外接头构件的肩部抵靠内圈的较大端面。 内圈的较大端面形成为地面。 靠在较大端面上的外侧接头构件的肩部的端面形成为地面或车削面。 内环的至少较大端面的表面粗糙度Ra被限制在0.1〜0.3的范围内。
