ABSTRACT:
A water guard for use in a rolling mill wherein the neck of a roll is rotatably supported in an oil film bearing contained in 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 flexible seal mounted on the roll neck for rotation therewith. The water guard is circular and it has a radially extending mounting flange integrally joined at its inner edge to an angularly outwardly extending sealing flange. The mounting flange is adapted to be surrounded by and to be secured to the seal end plate, and to provide the sole means for supporting and maintaining the sealing flange in frictional contact with the roll end face. Both the water guard flanges are elastically flexible with the mounting flange having a rigidity which is greater than that of the sealing flange.
