ABSTRACT:
A rolling mill oil film bearing has a sleeve with a tapered interior surface axially received on and rotatably fixed with respect to a tapered section of a roll neck. The sleeve has a cylindrical outer surface journalled for rotation within a bushing contained in a chock, with the chock, bushing and sleeve being axially removable as a unit from the roll neck. The sleeve is machined from a cylindrical forged blank which has a maximum outer diameter equal to the diameter of the sleeve's cylindrical outer surface. At least one element separate from the forged blank is secured to the sleeve. The element has a radially protruding outer portion engageable by the bushing during axial removal of the bearing unit from the roll neck.
