Abstract
The invention relates to a double-row wheel bearing unit for a vehicle, comprising an axle journal fixed to the vehicle, and a wheel hub bearing a wheel flange rotatably mounted on said axle journal by means of two rows of rolling bodies spaced axially apart. In order to adapt the loading capacity of the rows of rolling bodies to the respective load conditions, the two rows of rolling bodies have different rolling circle diameters respectively adapted to the highest expected load.
