Abstract
A circular seal assembly is provided for a roll in a rolling mill. The roll has a neck with a tapered section leading from a roll end face to a reduced diameter section rotatably supported in a non-rotating bearing chock. The chock is spaced axially from the roll end face to define a circular gap therebetween, and the seal assembly is adapted to span the gap. The seal assembly comprises a rigid circular seal end plate adapted to be fixed to the chock at a location cooperating with associated resilient seal components to subdivide the gap into an inboard chamber adjacent the roll end face and an outboard chamber adjacent the chock. A vent connection is provided in an upper quadrant of the seal end plate between the inboard and outboard chambers.
