Shift cylinders are also provided on the drive side of the upper work roll and apply forces in both the work side direction and the drive side direction to the radial bearingB. The shift cylinders each apply a force in the same direction to the radial bearing and the thrust bearing when the upper work roll does not shift in an axial direction at least during rolling.
