Patent ID: 8632076

Claim:
A sealing assembly for insertion between first and second mechanical elements subjected to possible offset positioning, comprising: a reinforcement ring, and at least one elastomeric sealing element in which the reinforcement ring is at least partially embedded, and wherein the sealing element having an annular membrane shaped as a truncated-cone sleeve and free from the reinforcement ring, which membrane obliquely extends in the radial section so as to protrude from the reinforcement ring, towards a symmetry axis of the sealing assembly and ends with at least one annular sealing lip intended to slidingly cooperate with a first mechanical element; and wherein the membrane is delimited by a lateral wall which has, in the radial direction, a relatively thin thickness, thinner than that of the at least one sealing lip, so as to be highly flexible, and wherein the membrane further has a plurality of stiffening ribs obtained in one piece with the lateral wall of the membrane, as localized thickenings of the membrane, and extending in the axial direction parallel to one another, spaced apart from one another to form on the membrane a crown of longitudinally extending radial projections.
