ABSTRACT:
A bidirectional hydrodynamic shaft seal includes an annular plastic disk having a sealing surface or lip provided with two connected spiral grooves extending around the disk axis. One of the spiral grooves spirals outwardly in a clockwise direction, and the other spiral groove spirals outwardly in a counterclockwise direction so that the spiral grooves have multiple intersection points. The shaft seal is designed for operation in either or both directions of shaft rotation.
