High Pressure Heavy Duty Double Acting Large Bore Hydraulic Ram Manufacturers

Double acting hydraulic cylinder
A double-acting hydraulic cylinder has a port at each end, supplied with hydraulic fluid for both the retraction and extension of the piston. A double-acting cylinder is used where an external force is not available to retract the piston or where high force is required in both directions of travel.
• Differential cylinders
• Double rod cylinders
• Tandem cylinders
• Rapid traverse cylinders
• Telescopic cylinders

The cylinder is made of alloy steel or medium carbon steel. After milling, pressing and such advanced processing technology, the roughness of the cylinder's inside surface is reduced, the friction gets smaller, and the service life of the seals is extended. The two ends of hydraulic cylinder are equipped with buffer devices with good performance, which effectively relieves the inertial force generated by the end of travel, reduces the high speed and peak pressure to the least, lowers the noise and impact load.

Features + Benefits
