  • Patent number: 11359725
    Abstract: A radial shaft seal seals a rotating shaft guided out of a liquid-loaded interior chamber, has a seal housing, an annular sealing body therein bearing against and sealing the shaft using a sealing lip, and an annular, metallic supporting body positioning the sealing body/bodies to seal interior from exterior. The supporting body presses the sealing body against the housing rear wall and is press fit and weldable there. A positioning cylinder with an outer shell is on the supporting body. An elastomer sealing body positioning cap with an elastomer sealing body is press fit on the outer shell so that the sealing body bears against a supporting body supporting web press-on collar and has a self-supporting supporting arch web, at the pressure space-side end of which is the sealing lip. A cord spring is centrally above the arch web on the sealing body outer circumference in an outer groove.
