Wheel bearing unit embodied as an angular contact ball bearing

A wheel bearing unit embodied as an angular contact ball bearing with a central axis, comprising:

• at least two first rows of bearing balls,
• at least two second rows of bearing balls, the second rows being arranged parallel to the first rows,
• an outer ring assembly extending around all the balls together radially on the outside,
• a first pairing formed from a first one of the first rows of balls and from a first one of the second rows of balls, each row of the first pairing being preloaded against a second pairing formed from a second one of the first rows of balls and from a second one of the second rows of balls, each of the pairings having a ball cage to guide the balls of both its rows, the outer ring having located axially on each side of a radially inwardly projecting rim a first inner raceway for one of the first rows of balls at one axial side of the rim and a second inner raceway, adjacent to the first inner raceway, for one of the second rows of balls at the other axial side of the rim.
