Abstract
A sealing assembly including at least one first annular shield having a sleeve portion integral in use with a rotating member and a flange portion, which radially and overhangingly extends from the sleeve portion. Preferably, a second annular shield is arranged in front of the first shield with the interposition of an annular seal; wherein the sleeve portion of the first shield is delimited by a conic-truncated lateral mounting surface having a tapering facing so as to have a greater diameter arranged on the side of the flange portion and intended to couple in use with a mounting seat of the rotating member formed by a shallow recess delimited by a conic-truncated bottom wall having the same tapering as the lateral mounting surface and by an axial shoulder which is arranged on the side opposite to the flange portion.
