ABSTRACT:
An annular shaft seal includes an elastic sealing lip which carries a twist element at its contact surface at the side exposed to air. The twist element is designed to return any liquid which may have exited to the air side back to the liquid side of the seal over the sealing edge, with both directions of rotation of the shaft. At least two sinusoidal twist ribs having the same amplitude and phase are shifted in phase position and bear snugly and tangentially against the sealing edge.
