ABSTRACT:
Actuator device for axially shifting rolls which can be powered rolls journaled by way of radial bearings in holding elements in a rolling mill frame, uses hydraulic cylinders. At the drive side, the journal portions of the working rolls are respectively stepped to provide a centering roll portion, onto which respectively, an axial bearing is mounted to be positively held in position. At the housing of this bearing is attached a hydraulic cylinder which carries out the adjustment/control operation. The respective locking after mounting a new roll, for example, is achieved by a spindle head which is slipped on and which transmits the motive power of a driving spindle by way of the locking function performed by this spindle.
