Patent ID: 8215647

Claim:
A roll neck seal for the bearing of a roll in a rolling stand, where the roll neck seal has: a single annular seal body ( 50 ), which is nonrotatably connected with a roll neck ( 2 ) by a bearing surface ( 53 ), oriented coaxially with the roll axis ( 52 ) and with at least two spaced webs ( 54 , 55 ) that face away from the roll axis ( 52 ) for direct or indirect contact with an annular projection ( 7 ) of the roll bearing, and a single reinforcing element ( 51 ) for reinforcing the seal body ( 50 ), wherein the reinforcing element ( 51 ) is embedded in the seal body and has a width ( 60 ) that is greater than the outside separation ( 59 ) of the two webs ( 54 , 55 ), wherein bearing surfaces ( 53 - 1 , 53 - 2 ) in contact with the roll neck ( 2 ) are each constructed symmetrically to radial center planes ( 61 , 62 ) of the webs ( 54 , 55 ), and the bearing surfaces, which are constructed independently each other, are designed in such a way that the radial pressing of the annular seal body ( 50 ) occurs in such a way that the prestressing of the webs ( 54 , 55 ) and their continuation, the sealing lips ( 65 ), relative to the annular projection ( 7 ) is equal, and no tilting moments act on the webs ( 54 , 55 ).
