First Claim
1. 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 for establishing a seal between the shaft and the housing, said seal assembly comprising:
- a circular flinger mounted on the shaft for rotation therewith at a location interposed axially between the work roll and the housing, said flinger having an annular contact surface extending radially from the roll shaft and facing toward the housing;
a seal end plate fixed to the housing;
a seal holder carried by the seal end plate, said seal holder having a circular groove facing toward said contact surface; and
a resilient seal having a circular base received in said groove and having a pair of flanges extending from said seal holder to terminate at radially spaced edges in sealing contact with said contact surface along inner and outer radially spaced circular lines.
