摘要

A seal assembly for use in an oil film bearing rotatably supporting a roll in a rolling mill. The seal assembly includes a flexible seal mounted on a tapered intermediate section of the roll neck for rotation with the roll and within a fixed circular seal end plate. The seal end plate has a stepped interior defining annular inboard and outboard sealing surfaces, with the outboard sealing surface having a diameter larger than the diameter of the inboard sealing surface. The flexible seal has inboard and outboard flanges projecting radially into contact respectively with the inboard and outboard sealing surfaces of the seal end plate.
