Abstract: A shaft packing includes a casing and at least two polymeric disks. One disk forms a protective lip and the other disk forms a packing lip. The internal diameters of the disks are smaller than the external diameter of the shaft to be packed. Between the two disks is positioned an expanding ring which ensures an inversion and expanding of the packing lip in the opposite direction to the protective lip.

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.

Abstract: A seal for sealing the end of a shaft passing out of the end wall of a casing and for sealing the end wall includes a gasket receptacle produced as a light metal pressure die casting. A sheet metal ring with a shaft seal ring molded onto it is pressed radially and axially into a recess in the die casting. The gasket receptacle is plastically deformed and the radial internal dimension of the sealing edge of the seal ring is set within the requisite narrow tolerance limits. A radially directed outer portion of the sheet metal ring is covered on both sides with elastomer.

Abstract: A seal for sealing the end of a shaft passing out of the end wall of a casing, as well as for sealing the end wall, is characterized in that a gasket receptacle is manufactured as a light metal pressure die casting, that a polytetrafluoroethylene sealing member is pressed from one side of the gasket receptacle towards which a recess is open and the radially outer portion of the shaft seal ring is injected round on either side with an elastomer material via a connecting channel of the die casting towards an end wall-side groove for receiving a static gasket during its moulding to the gasket receptacle. In the final operating stage, the sealing lip of the sealing member penetrated by a tube is bent axially by drawing onto a sleeve.

Abstract: A shaft seal in which a sealing lip provided on an elastomeric portion of a first annular member is in sealing contact with a sealing surface of a second annular member which in operation is adapted to rotate relative to the first annular member, and in which an annular elastomeric support portion provided on the first annular member supports axial forces on a radial surface of the second annular portion. The support portion includes protrusions with apices which cooperate with the radial surface of the second annular member and are distributed circumferentially at uniform intervals.
