Abstract

A seal assembly for a shaft extending out of a casing and, in particular, the crankshaft received in the crankcase of a motor vehicle includes a gasket receptacle in the form of a metal die casting having a passage opening for the shaft. A dynamic shaft seal ring is inserted in the passage opening of the gasket receptacle and a static gasket separate from the shaft seal ring and made from the same elastomer material as the ring is located on the side of the receptacle facing the casing. The shaft seal ring and the static gasket are moulded from the same side and in one operation onto the gasket receptacle.
