  • Patent number: 10130922
    Abstract: A receptacle has a wall defining a receptacle interior and a shaft housing for guiding a shaft through the wall into the receptacle interior. The shaft housing defines an annular cap with spaced apart inner and outer walls connected by an inner end face facing the receptacle interior. A shaft guide part has an end facing the receptacle interior and an outer surface that defines a gap relative to the inner wall of the shaft housing. The shaft guide part has an annular wall spaced apart from and parallel to its outer surface. The annular wall extends over the free end of the inner wall of the shaft housing and is sealed to the inner and outer walls of the shaft housing by at least one seal each. The shaft guide part is mounted in the shaft housing by a radial ball bearing and by an axial ball bearing.
