Abstract: 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.

Abstract: An apparatus for retaining a bearing assembly on the neck of a roll in a rolling mill. The apparatus includes an adaptor element having outwardly projecting first lugs circumferentially separated by first flutes. Fasteners detachably secure the adaptor element to a distal end of the roll neck. A locking element, which comprises an integral component of the bearing assembly, has inwardly projecting second lugs circumferentially separated by second flutes. The locking element is rotatable between an unlocked position at which its second lugs are aligned with the first flutes of the adaptor element to accommodate axial shifting of the bearing assembly onto and off of the roll neck, and a locked position at which its second lugs are aligned with the first lugs of the adaptor element to axially retain the bearing assembly on the roll neck.
