ABSTRACT:
In a rolling mill, for use in combination with a rotatable shaft protruding from a housing, with a work roll mounted on the shaft for rotation therewith exteriorly of the housing, a seal assembly is disclosed for establishing a seal between the shaft and the housing. The seal assembly comprises a circular flinger mounted on the shaft for rotation therewith at a location interposed axially between the work roll and the housing. The flinger has an annular contact surface extending radially from the roll shaft and facing toward the housing. A seal end plate is fixed to the housing and carries a seal holder which has a circular groove facing toward the contact surface. A resilient seal has a circular base received in the circular groove and a pair of flanges extending from the seal holder to terminate at radially spaced edges in sealing contact with the contact surface along inner and outer radially spaced circular lines.
