摘要： To provide a wheel support bearing assembly, in which the sufficient proof strength of an inner race during assemblage onto the vehicle body can be secured without its function being lowered, the wheel support bearing assembly includes an outer member, an inner member, and rows of rolling elements interposed therebetween. The inner member includes an hub axle having a flange and an inner race on an inner race mount, with raceways defined in the hub axle and the inner race. The inner race has a counterbore at its inboard end. The hub axle has a plastically deformed portion which engages an axially oriented surface of the counterbore when radially outwardly crimped and does not protrude outwardly beyond an inboard end face of the inner race. The difference P between the inner race mount and an outer peripheral face of the plastically deformed portion is 0.13 mm or more.
