An oil film bearing is disclosed for a rolling mill roll having a tapered neck leading to a reduced diameter end section. The bearing comprises an internally tapered sleeve received in a seated position on the tapered roll neck. The sleeve is journaled for rotation in a bushing fixed within a chock assembly. A tubular piston is received on and fixed relative to the reduced diameter end section of the roll. A cylinder is internally subdivided by the piston into first and second chambers. A sleeve ring abuts an end of the sleeve and a circular thrust component is interposed between and arranged to overlap adjacent segments of the sleeve ring and the piston. One or the other of the first and second chambers may be pressurized, whereupon pressurization of the first chamber will cause the cylinder to axially advance and act via the thrust component and the sleeve ring to urge the sleeve into its seated position, and pressurization of the second chamber will cause the cylinder to axially retract and act via the chock assembly and the bushing to withdraw the sleeve from its seated position
