Abstract
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.
