Abstract
A sealing system for a roller bearing including a first annular shield and a first sealing cover. A first face of each that includes a coupling surface that is covered with a rubbery coating made of a synthetic rubber. The coupling surface of the first annular shield is coupled to a corresponding coupling surface of a rotating ring of the roller bearing, and the coupling surface of the first sealing cover is coupled to a corresponding coupling surface of an outer ring of the roller bearing. Each of the first annular shield and the first sealing cover is pressed from a metal sheet with a first face entirely rubberized with the rubbery coating.
