A radial shaft seal, which includes a ring-shaped, metal supporting body and a sealing lip disposed thereon, in order to separate a hydraulic side that is particularly under high pressure, from an atmospheric side, the sealing lip being pressed onto the shaft by an annular helical spring. In an uninstalled sealing ring, the working plane of the annular helical spring has a value x that is less than zero with respect to the working plane of the sealing edge, and in an installed sealing ring, the two working planes are approximately coplanar.
