The patent relates to a sealing ring, with an annular body 1, 2 consisting of an elastomer layer 1 which is integrated on a metal housing 2 and has radial sealing lips 3 which can be pressed against the shaft 4 by means of an annular spring 5, or to an integrated sealing system consisting of a mounting structure 30 in which all of the elements required for sealing the rear end of a crankshaft are integrated, including an elastomer element for radial sealing 31. The said sealing ring or sealing system are provided with a disposable mounting device 10 consisting of an inner ring, concentric with the sealing ring, made of inexpensive material with an outer surface 11 having the same diameter as that of the receiving shaft portion 12 and on which originally the sealing ring or the sealing system is mounted; the outer surface 11 has, on one of its ends, a bead 13 for centring on the shaft portion 12 receiving the sealing ring or the sealing system, which bead extends substantially parallel to the geometrical axis "x" of the shaft 4, with an inner curved surface 14 for resting on the rounding 15 of the shaft portion 12 receiving the sealing ring or the sealing system, and part of said bead 13 is an outer surface, constructed as shoulder 16, for opening and guiding the radial sealing lips 3 of the sealing ring or sealing system, having a somewhat larger diameter than that of the outer surface ...
