Adjustment device

A system for adjusting a roll in a roll support, the system comprising:

• an adjustment device for adjusting the roll in the roll support, the adjustment device comprising:
• a cylinder housing fastened to the roll support and a piston in the cylinder housing, guided in the cylinder housing so as to be movable in translation in the cylinder housing;
• a coupling rod fastened to the piston;
• a travel measurement device connected to the coupling rod for and configured for determining a position of the piston;
• the piston including a piston base thereon located along the piston, a guide element of the piston and which extends from the piston base in the direction of the travel measurement device, and the coupling rod is fastened to the guide element;
• the travel measurement device is arranged on an opposite side of the roll support from the cylinder housing;
• a guide opening in the cylinder housing,
• the guide element is guided in the guide opening of the cylinder housing;
• a bore in and extending through the roll support;
• a sliding guide for slidably guiding the coupling rod through the bore in the roll support, the sliding guide is arranged within an end of the bore in the roll support facing the travel measurement device, wherein the coupling rod connects the piston and the travel measurement device and is guided at least partially through the bore in the roll support, wherein the bore is configured as a recessed bore comprised of a greater diameter at the end facing the cylinder housing than at the opposite end, wherein the guide element is a piston rod with a circular cross section, and wherein the guide element extends through the cylinder housing and into the end of the bore having the greater diameter.
