摘要： A rotary seal interposed between an axially and rotatably movable shaft and stationary housing, the seal having a flexible annular boot or diaphragm mounted in surrounding relation to the shaft and terminating in an outer peripheral margin which abuts a seal ring, the seal ring having a tapered face engaging a sloped surface on the outer stationary housing. A spring-loaded member urges the seal ring into firm engagement with the housing portion, and the outer free end of the boot is free to be radially displaced along its interface with the seal ring while urging the seal ring in an axial direction firmly into engagement with the sloped portion on the stationary housing.

摘要： A rotary facial seal and a thrust bearing are adapted to be installed between inner and outer concentric relatively movable members, such as, the spindle housing and axle of a motor vehicle, the facial seal having an annular diaphragm made up of an inner seating portion mounted on the axle, an outer sealing lip tapering away from a hinged section in a seal body to engage a radial wall of the housing, and an intermediate resilient wall section between the seal lip and seating portion to yieldingly urge the sealing lip into a thin band of contact with the radial wall under the biasing action of the intermediate wall section; and the thrust bearing includes a bearing member which is installed at the inner bore of the spindle housing and is freely rotatable with respect to the spindle housing when engaged by the end of the shaft and inner seating portion of the facial seal.
