ABSTRACT:
A sealing cover for a housing is provided with a hole for passage of a shaft which extends through the cover. The cover comprises a metal cover body; a dynamically acting seal for the shaft, the dynamically acting seal comprising at least one elastic sealing lip which is vulcanized to the body; a statically acting seal for sealing the cover flange face, the statically acting seal comprising elastic sealing strips projecting axially with respect to the direction of the shaft which are vulcanized to the body. The improvement in the cover includes the body composed of a profiled, drawn sheet-metal body having an essentially cup-shaped cross section and the body has first, second and third faces which are offset from one another in the axial direction of the shaft and extend radially with respect to the axial direction, the third face includes a way for connecting the body to the housing, the second face is between the first and the third faces and receives the sealing strips, and the sealing lip is vulcanized to the first face.
