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.

摘要： Provided are a method of manufacturing an outer race which contributes to extension of a bearing life and allows rolling elements to stably roll, an outer race for a double-row angular bearing, and a wheel bearing device. Further, provided is a double-row angular bearing which is excellent in both strength and rigidity and which can be endowed with a longer life and higher quality. At least one of an inner race and the outer race is formed by a cold rolling process. Hardness prior to the cold rolling process of a blank is set to Rockwell Hardness 30 HRC or less. The outer race is formed by performing the cold rolling process on the blank including a circumferentially protruding portion which is provided on a radially inner surface of the blank and protrudes to a radially inner side of the blank.
