Abstract
A radial shaft seal ring for sealing a space between a shaft and a bore in a housing includes a support body having an axial part, a radial part and a curved connecting part connecting the axial part to the radial part. A seal body is mounted on the support body and has a static seal element configured to seal between the support body and the bore and a dynamic seal element configured to sealingly abut against the shaft. The static seal element extends from the axial part of the support body over the connecting part to the radial part of the support body and includes an axial seal element section and a radial seal element section. A radially outer surface of the static seal element has a radially outwardly directed first seal bead, at least a portion of which is located directly radially outward of the curved connecting part.
