Abstract
The interchangeable wheel bearing unit has a wheel hub and two tapered roller bearings, each having an outer ring and an inner ring, between which a respective row of tapered rollers is situated, and a securing ring in at least one of the inner rings of the tapered roller bearing. To assemble the wheel bearing unit without special tools, each outer ring of the tapered roller bearings has a cylindrical extension, which runs coaxially with the wheel hub axis towards the outer face of the bearing and into which a respective seal is inserted, and a retaining element, which is supported on the corresponding inner ring and axially fixes the outer ring, is located on the opposite face of the respective tapered roller bearing from the seal.
