    摘要: A device including a sealing assembly having a first annular shield constrainable to a rotating first member, a second annular shield facing the first shield and constrainable to a stationary second member, and an annular seal supported by the first shield and provided with annular lips cooperating with the second shield. The device has a signal generator device having a third shield constrainable to the first member and an annular signal generator element arranged facing the first and the second shields; wherein the first shield has a flange portion, having on a side of the first shield, a first and a second L-fold in opposite directions which delimit a first annular surface facing the annular lips and the second shield; wherein the annular signal generator element is delimited towards the second shield by a second annular surface facing the annular lips forming an obtuse angle with the first annular surface.

    摘要: A sealing device for a hub-wheel assembly that includes a rolling bearing is provided. The sealing device being has a screen assembled on an outer ring of the bearing and has an annular cylindrical wall, having an internal lateral surface press fit along an external lateral surface of a collar of the outer ring. The internal surface has a respective inner diameter (Di) and the external lateral surface has a respective outer diameter (De). A static sealing element is constrained to the screen; the ratio of the interference between inner diameter (Di) and outer diameter (De) over a screen thickness ranging between 0.22 and 0.5; a coupling length (L, L′) between the internal lateral surface and the external lateral surface is equal or greater than 5 mm; and a ratio between outer diameter (De) of the external lateral surface and coupling length (L, L′) ranging between 1 and 1.19.

    摘要: 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.
