ABSTRACT:
A coolant seal for use in a rolling mill wherein the neck of a roll is rotatably supported in an oil film bearing contained within a bearing chock, with a seal assembly located between the roll end face and the bearing chock to retain oil in the bearing and to exclude contaminants such as cooling water, mill scale, etc. from the bearing. The seal assembly includes a circular seal end plate fixed relative to the bearing chock at a location surrounding a circular flanged seal mounted on the roll neck for rotation therewith. The coolant seal is circular, with a radially disposed mounting flange integrally joined at its inner edge to a sealing flange extending angularly and flexibly therefrom. The mounting flange is secured to a mounting surface on the seal end plate at a location placing the sealing flange in frictional contact with the roll end face. The mounting flange is provided with an integral bumper protruding axially therefrom in one direction towards the roll end face, and an integral positioning shoulder protruding axially therefrom in the opposite direction in a recess in the mounting surface of the seal end plate.
