ABSTRACT:
A wheel support bearing assembly, in which the rigidity of an outboard portion thereof can be increased without increasing the weight of the bearing assembly. The wheel support bearing assembly includes outer and inner members and inboard and outboard rows of rolling elements interposed between outboard and inboard raceways defined in the outer and inner members confronting each other. The inner member includes a hub axle having a wheel fitting flange on an outboard side thereof, and an inner race member mounted on an inboard end thereof. The hub axle has an outer diameter measured at a point intermediate between the inboard and outboard rows of rolling elements that is greater than the minimum diameter of the raceway on the inboard side. A pitch circle diameter of the outboard row of rolling elements is greater than the pitch circle diameter of the inboard row of rolling elements.
