ABSTRACT:
A rolling stand with hydraulic adjustment of the mill rolls comprises a hydraulic cylinder whose piston is acted upon by the adjustment spindle and whose cylinder body, in turn, bears upon the block in which the back-up or pressure roll is journaled. The sliding seal of the piston rides in a cylinder lining which is disposed in the cylinder and is sealed relative to the latter with stationary O-rings so that pressure equalization on both sides of the liner is possible, thereby preventing expansion of the line upon subjection of the cylinder to high pressures.
