Abstract

Wheel bearing unit with a wheel hub, wherein the wheel hub has an integrally formed wheel flange on one end thereof and an inner ring that is rotatable together with the wheel hub, wherein the inner ring is fastened on the wheel hub through the use of a rolling rivet connection in order to pre-tension a row of rolling elements in relation to an outer ring, and with an encoder provided on the inner ring and extending radially towards the outer ring, and with a protective cover fixed on the outer ring in order to close and seal annular openings formed between the outer ring and the wheel hub, and wherein a cylindrical section of the protective cover is pressed in and wherein a bottom section extends inwardly from the cylindrical section in a radial direction in order to cover an inner-side end of the wheel hub, wherein the cylindrical section is joined with a substance bond to the outer ring and wherein the substance-bond connection is produced through the use of a hardening fluid and wherein the fluid is held in a filling reservoir provided between the cylindrical section and the outer ring.
