PROBLEM TO BE SOLVED: To provide a rolling mill capable of reducing the cost for valves, pipings and auxiliary machinery and extending the service life of the hydrostatic bearing part by reducing the fluid pressure of a bearing in a hydrostatic bearing part as much as possible. SOLUTION: In a flying pair cross type rolling mill for controlling the shape of a plate by making upper and lower work rolls 2 and back-up rolls 3 cross during rolling a metal plate, the lengths at least in the axial direction of the roll of a 1st liner 6, the 2nd liner 7 and a thread 8 are set that the load from a pressure block 10 is dispersed over the approximately entire length at least in the axial direction of the roll of a thread base 9 in which the hydrostatic bearing part 12 provided.
