Abstract
Apparatus for mounting a mill roll on a mill drive shaft in which mounting concentricity is produced by the internal expansion of the drive shaft to engage the bore of the mill roll. A secondary clamping device provides additional lateral binding force on the mill roll necessary for the production of the required frictional forces for the transmission of driving torque from the shaft to the mill roll.
