    • A vehicle wheel bearing apparatus has a substantially cylindrical outer ring formed with double row outer raceway surfaces on its inner circumference and with press fitting surfaces on its outer circumferences of its cylindrical portions. A pair of inner rings is formed with inner raceway surfaces on their outer circumferences. The inner rings cylindrical portions have fitting surfaces on their inner circumferences. The fitting surfaces fit onto a cylindrical portion of a wheel hub. The inner rings are adapted to be arranged so that end faces of the cylindrical portions abut each other. Double row rolling elements are freely rollably arranged between outer and inner raceway surfaces. At least the outer ring of the outer and inner is formed by pressing or rolling from a plate member or a pipe member. The outer ring and the inner rings have cylindrical portions axially extending, respectively, from the outer raceway surfaces and the inner raceway surfaces. The thickness of the cylindrical portions of the outer ring is thinner than that of the outer raceway surfaces. Seals are arranged in annular spaces formed between the inner circumferences of the cylindrical portions of the outer ring and the outer circumferences of the cylindrical portions of the inner rings. The seals are adapted to be press-fit into the inner circumferences of the cylindrical portions of the outer ring. The double row outer raceway surfaces of the outer ring and the inner raceway surfaces of the inner ring are surface hardened.
    • 车轮轴承装置具有在其内圆周上形成有双列外滚道表面的大致圆柱形的外圈,并且在其圆柱形部分的外周上具有压配合表面。 一对内圈在其外圆周上形成有内滚道表面。 内环圆筒部分在其内圆周上具有配合表面。 装配表面装配在轮毂的圆柱形部分上。 内环适于布置成使得圆柱形部分的端面彼此邻接。 双排滚动元件可自由滚动地布置在外滚道表面和内滚道表面之间。 至少外,外的外圈通过从板构件或管构件的挤压或轧制而形成。 外环和内圈具有分别从外滚道表面和内滚道表面轴向延伸的圆柱形部分。 外圈的圆筒部的厚度比外滚道面的厚度薄。 密封件布置在形成在外圈的圆柱形部分的内周和内圈的圆柱形部分的外圆周之间的环形空间中。 密封件适于压配合到外圈的圆柱形部分的内圆周中。 外圈的双列外滚道表面和内圈的内滚道表面被表面硬化。
