Abstract
A lip sealing ring has a lip engaging a shaft, the lip being at one end of a flexible sleeve which surrounds the shaft and is supported by its other end in a housing. The sealing lip is supported by a pair of stiffening rings, one on the inside and one on the outside of the sleeve, to ensure adequate sealing while allowing the sleeve to be sufficiently flexible to accommodate displacements of the shaft.
