SCHERMATURA DI PROTEZIONE A BASSO ATTRITO PER CUSCINETTI VOLVENTI

摘要

Shields made of plate and plastic or elastomeric materials have a plane surface which forms a seal with the inner ring. The inner surface (17) of the ring (11) with which the shields (14) form a seal has recesses (19) along the sections in which the seal are formed, which define pockets between the surface of the ring and the surface of the shield; the pockets serve as containers for the foreign bodies which penetrate through the seal and for the grease which tends to come out through this latter.
