A rolling mill oil film bearing has a sleeve (50) with a tapered interior surface (52) axially received on and rotatably fixed with respect to a tapered section (12) of a roll neck. The sleeve has a cylindrical outer surface (54) journalled for rotation within a bushing (22) contained in a chock (24), with the chock, bushing and sleeve being axially removable as a unit from the roll neck. The sleeve (50) 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 (52,62) separate from the forged blank is secured to the sleeve. The element has a radially protruding outer portion (56b,62c) engageable by the bushing (22) during axial removal of the bearing unit from the roll neck. |
