ABSTRACT:
A radial shaft sealing ring has at least one dynamically stressed first seal and at least one statically stressed second seal. The first and second seals are connected to a support ring having a centering seat that is placeable into a housing bore. The support ring has an axial projection which at least partially covers the second seal so as to limit its elastic deformation, and may further contact a housing to be sealed.
