摘要： A sliding portion between a seal lip (7) and the circumference of a shaft (3) is made of a sliding face (10) so that the facial pressure at the initial action time can be lowered to suppress the proceeding of the wear of the seal lip (7) thereby to elongate the lifetime of a sealing device (1). Moreover, screw ridges (12) are formed from an atmospheric side slope (11) to a sliding face (10) so that satisfactory sealing properties can be exhibited initially and endurably for a long time.

摘要： Lip-type oil seals (10) having helical pumping ribs (40) are manufactured by preparing a molded foreproduct of the seal and by trimming a hat portion (62) to form a sharp sealing edge (32). Each of the pumping ribs (40) is configured to include a first section (50) of a uniform cross-section and a bilge-shaped second section (52). Trimming is made along a trim line (68) that intersects in between the length of the first sections (50) to ensure that a length of the first sections (50) is preserved between the sealing edge (32) and the second sections (52) regardless of the tolerance of positioning of a trimming knife. Oil seals having an improved initial static and dynamic sealing performance is obtained. The second sections (52) achieves a satisfactory pumping action even after a substantial wear has taken place.
