Abstract

A seal (1) designed for insertion between a rotating shaft (2) and a fixed casing (3) having an opening (6) through which the shaft (2) is fitted, the seal having a sleeve (31) designed to fit onto the shaft (2); a first sealing ring (8) fitted to the sleeve (31); a cup (10) designed to fit inside the opening (6); and a second sealing ring (9) connected to the cup (10) by a bellows (24) of elastomeric material; the first and second sealing rings (8, 9) cooperate frontally with each other under the axial load exerted by a spring (33) interposed between the cup (10) and the second sealing ring (9); and the bellows (24) is connected in angularly free manner to the cup (10) to prevent self-induced torsional oscillation and noise resulting from it.
