22605/96 ABSTRACT A sealing ring for a rotary shaft which serves to retain and/or return a lubricant, has a generally annular rigid supporting member carry- ing a generally annular sealing member, made of an elastic material, and defining a sealing lip, projecting radially inwards. On the atmospheric side of the lip spaced apart projections are formed,the bottoms of the projections, in assembled state, resting against the shaft, the contact surfaces thereby formed and by which the bottoms are in contact with the shaft being limited by at least one edge which runs from a point lying at a distance from the adjacent limiting edge of the contact surface of the sealing edge obliquely toward the limiting edge, at a. sharp included angle. The sealing lip is formed such that, in assembled state, the contact surface by which the sealing edge of the lip is in contact with the shaft is, at least on the lubricant side, at least partially limited by edges running obliquely with respect to the center line of the shaft.
