  • Publication number: 20120068419
    Abstract: A low friction seal for sealing between a shaft and a bore and includes an inner case adapted to be mounted on the shaft. An outer case is adapted to be mounted within the bore. A seal element is mounted to the inner case and includes a base portion attached to the inner case. A membrane extends from the base portion and an axially extending leg extends from the membrane. A seal lip extends from the axially extending leg and sealingly engages a radially extending portion of the outer case. As the shaft rotates, the centrifugal forces tend to cause the membrane to flex and the torque loads applied by the dynamic seal are reduced to the point that the seal lip can lift off and apply zero torque load.
