摘要

A seal is disclosed for use in a rolling mill oil film bearing in which a sleeve (12) is mounted on a roll neck (14) for rotation therewith, the sleeve (12) is journalled for rotation in a fixed bushing (18), and a flow of oil exits from between the sleeve (12) and the bushing (18). The seal comprises a flexible circular seal body (25) adapted to be mounted on and to rotate with the roll neck (14). Circumferentially spaced impellers (42) project from the seal body (25). The impellers (42) are rotatable with the seal body (25) and serve to rotatively propel oil exiting from between the sleeve (12) and bushing (18).
