ABSTRACT:
A roll assembly having a roll cylinder, a roll core and pressure transfer elements, which assembly is tightened for a grinding operation by applying hydraulic pressure through the pressure transfer elements and aligning the plane of the hydraulic overall pressure force to reduce to about zero the bearing play in the area of the contact line of the grinding wheel. The roll cylinder is mounted on the roll core through antifriction bearings, and in the finished apparatus, such as a calender, reduction of bearing play will compensate for wall thickness errors in the races of the antifriction bearings.
