A wheel bearing unit which has at least one outer part, at least one inner part and at least two rows of rolling bodies between the outer part and the inner part. One inner raceway is formed on the outer part and one outer raceway is formed on the inner part for the rolling bodies of each row. The wheel hub has internal toothing, which projects radially inwards in the direction of the rotational axis, for engaging external toothing on a drive pin. The internal toothing of the hub is rotationally fixedly coupled to the outer raceway. The ratio of the diameter dof a tip circle of the internal toothing to the bearing width bof the outer part is greater than 0.9.
