Provided are a bearing device for a wheel and a method for installing the bearing device for the wheel, the bearing device for the wheel being capable of improving maintainability while suppressing limitations on the design of internal specifications. A bearing device for a wheel is provided with: an outer ring; an inner member (a hub ring and an inner ring) having double rows of inner track grooves facing the double rows of outer track grooves of the outer ring, and a wheel attachment flange; a double-row ball row; and a hub bolt press-fitted into a bolt hole of the wheel attachment flange, the outer ring having a first outer peripheral surface, a second outer peripheral surface having a smaller diameter than the first outer peripheral surface, and a stepped surface connecting the first outer peripheral surface and the second outer peripheral surface, the outer diameter radius dimension of the first outer peripheral surface being larger than the inscribed circle radius of the head of the hub bolt press-fitted into the bolt hole, and the outer diameter radius dimension of the second outer peripheral surface being smaller than the inscribed circle radius of the head of the hub bolt press-fitted into the bolt hole. The outer diameter radius dimension of the second outer peripheral surface is smaller than the inscribed circle radius of the head of the hub bolt pressed into the bolt hole.
提供一种车轮用轴承装置及车轮用轴承装置的设置方法,该车轮用轴承装置能够抑制对内部规格的设计产生限制的同时提高维修性。车轮用轴承装置具备:外圈;内方构件(轮毂圈以及内圈),其具有与外圈所具有的双列外侧轨道槽对置的双列内侧轨道槽以及车轮安装凸缘;双列滚珠列;以及轮毂螺栓,其被压入车轮安装凸缘的螺栓孔,外圈具有:第一外周面、直径比第一外周面小的第二外周面、以及连接第一外周面与第二外周面的台阶面,第一外周面的外径半径尺寸比压入到螺栓孔的轮毂螺栓中的头部的内切圆半径大,第二外周面的外径半径尺寸比压入到螺栓孔的轮毂螺栓中的头部的内切圆半径小。
