Summary:An axle bearing apparatus includes a hub shaft (1) for common use with a driving wheel bearing apparatus (D) and a driven wheel bearing apparatus (F), the hub shaft including an axle-mounting flange (2) formed at its outer end portion, and a cylindrical portion (4) formed at an inner side of the flange and having a through hole (5) formed in a center portion of the cylindrical portion, and a bearing portion (10) press-fitted on the cylindrical portion of the hub shaft and including an inner ring (11), an outer ring (12) and rolling elements (13) disposed between the inner and outer rings. The hub shaft is used for the driven wheel bearing apparatus, and alternatively the through hole in the hub shaft is enlarged in diameter, and a spline (9) are formed axially in an inner surface of the diameter-enlarged through hole, and the hub shaft thus processed is used for the driving wheel bearing apparatus.
