A sleeve is disclosed for use in an oil film bearing of the type employed to rotatably support the tapered neck of a roll in a rolling mill. The sleeve is machined from a hollow forging of a base metal with a cylindrical outer surface and a tapered inner surface adapted to be seated on the tapered roll neck.
