PURPOSE: A device for fixing a rolling roll assembly is provided to prevent damage to a cylinder and the leakage of oil by transferring a piston using oil without a spring. CONSTITUTION: A device for fixing a rolling roll assembly comprises a first oil groove(30) which is formed in the center of a cylinder piston fixing the bottom of a rolling roll assembly to transfer the piston to one side, a second oil groove(40) which is formed on one side of the piston to transfer the piston to the other side, a first inflow hole(11) which is formed in a cylinder to inject oil into the first oil groove, a second inflow hole(12) which is formed in the cylinder to inject oil into the second oil groove, and a sealing groove(50) which is formed on one side and the center periphery of the piston to insert a sealing. |
