To provide a rolling machine which can reduce unbalanced load onto a bearing with even a simpler structure compared to a conventional one, and a rolling method.SOLUTION: Two or more first cylinders are so provided on each of an inlet side and an outlet side in a rolling direction as to be arranged in an axial direction. When bending a roll and at least a center of a bearing 790 is located between the first cylinder, which is located on the outermost side in the axial direction, and the first cylinder, which is located on the innermost side, of the first cylinders, a control apparatus 80 can select to drive one first cylinder on the inlet side and one first cylinder on the outlet side so that resultant force thereof is applied to a central portion of the bearing 790.SELECTED DRAWING: Figure 5 【課題】従来に比べて簡易な構造でも、軸受への偏荷重を低減可能な圧延機および圧延方法を提供する。【解決手段】圧延方向の入側および出側の各々に、第１シリンダが軸方向に並んで２つ以上設けられ、制御装置８０は、ロールのベンディング時、かつ第１シリンダのうち最も軸方向の外側に配置された第１シリンダと最も内側に配置された第１シリンダとの間に少なくとも軸受７９０の中心が配置されている時は、軸受７９０の中心部分にその合力が加わるように、入側のうち１つの第１シリンダおよび出側のうち１つの第１シリンダを駆動することが選択できるように構成された。【選択図】 図５
