Abstract
A bearing seal device seals the end of a ball bearing mechanism having an inner race engaging a cylindrical shaft, a plurality of balls, and an outer race. A flat elastic sealing ring abutts the inner race, which is inset, and bears against a sealing surface of the outer race. A circumferential seal engages and forms a seal on the shaft and abutts and forms a seal with the sealing ring. A bias means presses the circumferential seal against the sealing ring, which is deformed into a cup shape, and forms a seal with the sealing surface of the outer race.
