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.
