Large numbers of them are in use in many different applications. The sealing ring, the shaft and the sealed fluid form a complex sealing system. For a successfully operating sealing system an adequate combination of the components is required. Between the sealing lip and the rotating shaft there must be a thin lubricating film of oil. The “reverse pumping” process in the sealing zone prevents leakage through the film. This sealing mechanism is caused by microasperities on the lip surface and also affected by the shaft surface. In the sealing area most shafts are manufactured by plunge grinding. With rotary shaft lip seals they form a well operating sealing system, as the experiences of the last years show. However, this machining process takes long and is expensive. There is need at more economical processes for the machining of the sealing area on shafts. In some applications hard turned shafts are already used successfully. At Institute of Machine Components sealing systems with differently machined surfaces were examined. Ground, hard turned, rolled and shot-blasted shafts were used. The pumping effect and the friction torque were investigated in short-term tests. Leakage and wear of the sealing system were examined in 240h tests. The test results and their meaning for practice are explained. %@ 1855980916
