Abstract:
Sealing device for a rolling contact bearing, said device being comprised of:a rotating unit to be assembled fixedly connected with a rotating race of the bearing, comprised of a first annular metallic insert, which is comprised of a radial wall substantially disc-shaped and of a cylindrical wall portion; anda non-rotating unit to be assembled fixedly connected with a non-rotating race of the bearing, comprised of a second annular metallic insert which has a covering scaling with a first sealing lip suitable for sliding against the axially inner side of said disc-shaped wall, and a second second lip which extends in a radially inner direction to slide against said cylindrical wall;wherein said rotating unit comprises at least one substantially radial rotating surface with a given minimum diameter and that said non-rotating unit comprises at least one substantially radial non-rotating surface with a maximum diameter which is lesser than said minimum diameter, and is formed by at least one circumferential relief extending in an inner radial direction and made of rubber, where said units are reciprocally positioned in such a way that said rotating surface faces said non-rotating surface from an axially inner position to comprise an axial stopping means for the non-rotating surface, so as to provisionally restrain the two coupled units in relation to each other in order to assemble the sealing device onto the bearing in a correct arrangement.
