A radial shaft seal is disclosed having a sealing ring of polymeric material with at least one sealing lip supported on the shaft to be sealed by a backing ring positioned on the non-pressurized side of the sealing lip. The sealing ring is permanently adhered to a stiffening ring having an angled profile with a radially inwardly protruding leg that at least partly overlaps and directly contacts the backing ring. A process for the manufacture of such a radial shaft seal is also disclosed wherein the stiffening ring and the backing ring are together positioned in a tool cavity and the remaining free space of the tool cavity is filled with a liquid or pasty sealing material which is subsequently solidified and adhered to the sealing ring to produce a finished shaft seal. This provides a more economical process of manufacture than prior art shaft seals and results in a radial shaft seal of improved use characteristics.
