Abstract
A tool is disclosed for axially urging a bearing assembly into and out of a seated position on the neck of a roll in a rolling mill. The tool includes a piston surrounded by a cylinder. The piston is removably fixed to the roll neck and is configured to internally subdivide the cylinder into first and second chambers. Fluid conduits are arranged to alternatively pressurize the first and second chambers to alternatively shift the cylinder with respect to the thus fixed piston in opposite first and second directions. Movement of the cylinder in the first direction urges the bearing assembly into its seated position, and movement of the cylinder in the opposite second direction dislodges the bearing assembly from its seated position.
