Fluid pressure cylinder and rolling mill

摘要

Hydraulic cylinders are provided in a housing so as to be opposed to roll chocks. Each of the hydraulic cylinders is constituted by movably fitting a thin plunger via a liner into a cylinder fixed to the housing, movably fitting a concave portion of the thin plunger over a center guide on the cylinder to form guide means, and connecting a liner for thrusting each of the roll chocks to a front end portion of the thin plunger.
