Abstract
A tapered roller wheel bearing assembly may include: a hub provided with a hub flange for mounting a wheel formed radial outwardly at an end portion thereof and a hub raceway formed at a side portion close to the hub flange; an outer ring enclosing the hub and provided with an outer raceway corresponding to the hub raceway on an interior circumference thereof; and a tapered roller disposed between the hub raceway and the outer raceway and allowing a relative rotation of the hub and the outer ring, wherein a flange base is formed between the hub flange and the hub raceway and a first undercut for grinding the hub raceway is formed at the flange base, and wherein a second undercut for dispersing stress concentrated on the first undercut is further formed at the flange base.
