Zusammenfassung:To provide a rolling mill and a rolling method capable of reducing offset loads on bearings even with a simple structure as compared to conventional technologies.Two or more first cylinders 740, 741, 744, 745, are provided on each of the entry side and the exit side in the rolling direction, the two or more first cylinders being aligned in the axial direction, and a controller 80 is configured to be able to choose to drive one first cylinder on the entry side and one first cylinder on the exit side such that resultant force thereof acts on a central portion of a bearing when the roll performs bending and when at least the center of the bearing is arranged between the axially outermost first cylinder and the axially innermost first cylinder in the first cylinders.
