A coupling system for a sealing assembly with a rotating annular member. In particular, a bearing ring provided with a flange. The sealing assembly provides at least one first annular shield having a sleeve portion integrally coupled with the rotating annular member and a flange portion that radially and overhangingly protrudes from the sleeve portion and is arranged close to the flange. The sleeve portion is defined by a solid tubular body of rotation delimited by a mounting surface facing towards the rotating annular member and having cylindrical geometry, In combination, the sleeve portion couples with an assembly seat of the rotating annular member, formed by an annular shallow recess delimited by a cylindrical bottom surface and by an axial shoulder arranged on the side opposite to the flange; the first annular shield being placed, at the same time, in axial contact with the flange portion and the axial shoulder.
