Hydraulic Cylinder Blocks

Our company has been independently designing and producing hydraulic cylinder blocks for rolling mills for nearly 30 years. We have provided more than 3000 various types of hydraulic cylinder blocks to domestic and foreign customers, including work roll bending cylinder blocks, work roll support balance cylinder blocks, press down cylinder blocks, as well as cylinder blocks for cylinders 1, 2, 3, 4, and 5. There are cylinder blocks with elliptical plungers, universal cylinder blocks, and customized cylinder blocks designed according to customers' special technical requirements. The cylinder blocks produced by our company are reliable in operation, have a high safety factor, are resistant to high-pressure and high-speed impacts, and have a long service life.
