Zusammenfassung:	A wheel hub bearing unit includes a hub rotatable about an axis and having a flange connectable with a wheel, an inner ball raceway and an inner roller raceway. An outer ring is connectable with the vehicle and disposed about the hub and has an outer ball raceway and an outer roller raceway. A plurality of balls roll upon the inner and outer ball raceways and a plurality of tapered rollers roll upon the inner and outer roller raceways. A difference between a ball pitch circle radius and a roller midpoint circle radius is no greater than five millimeters. A vertex at the intersection of each line extending through the midpoint circle and a line extending through a midpoint of a spacing line segment is spaced from the axis by a radial distance, a ratio of the vertex radial distance to the midpoint circle radius is between 1.5 and 3.0.
