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 contact angle between the balls and the ball raceways has a value between ten degrees and forty degrees. Each line extending through ball inner and outer contact points intersects with a line extending through a roller midpoint circle at a vertex, the vertex being spaced from a midpoint of a spacing line segment between ball and roller pitch circles by an axial distance of no greater than 7.5 millimeters.
