SCHERMATURA DI PROTEZONE PER CUSCINETTI VOLVENTI

摘要

In shields made of plate, the end edge is overturned against the inner ring with which they form a labyrinth seal. The inner surface (16) of the ring (11) of the bearing with which the shields (14) form a labyrinth seal is provided with a step (15) situated near the edge (18) of the shield itself. The space (20) formed between the step (15) and the edge (18) of the shield retains the grease of the bearing which tends to come out; the pocket between the recess (19) and the edge (18) of the shield retains the grease which comes out and the foreign bodies which penetrate beyond the seal.
