Abstract

A roll stand includes a generally stationary frame, a roll centered on an axis, and a radial-thrust bearing having an outer race fixed in the frame, an inner race fixed on the roll, and a plurality of rollers radially engaging the races and supporting the roll in the frame for rotation about the axis. The rollers are axially shiftable along one of the races. An axial-thrust bearing has outer and inner faces one of which is axially fixed to the roll and the other of which is axially movable in the frame and rollers between the respective outer and inner races. An actuator is braced axially between the roll and the frame for axially shifting the roll in the frame and thereby axially shifting the other of the radial-bearing races relative to the respective rollers and the one radial-bearing race.
