A bearing unit includes a radially outer ring, a radially inner ring, and a sealing device. The inner ring includes a first radially outer surface formed, a second radially outer surface adjacent to the first, and a radial step connecting the radially outer surfaces. The sealing device includes a shaped shield mounted on the outer ring and an elastomer lining the shaped shield. The elastomer lining includes at least three radial contacting lips. A first, axially outer most radial contacting lip is in sliding contact with the first radially outer surface of the inner ring, a second, axially inner most radial contacting lip is in sliding contact with the second radially outer surface of the inner ring, and a third radial contacting lip positioned between the first and second radial contacting lips and in sliding contact with the second radially outer surface of the inner ring.
