Double Sided Hydraulic Cylinder

Double-ended hydraulic cylinders have a single rod with a centrally placed piston. The rod protrudes from both ends of the cylinder body. The double-ended hydraulic cylinder is commonly used as a steering cylinder, and they can generate force in both directions.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 it can be used where high force is required in both directions of travel.Double-rod cylinders are cylinders with a through piston rod and thus with two working areas of the same size for extending and retracting. Due to the through rod, these cylinders are about twice the size of cylinders with one-sided piston rods.A Double Acting cylinder uses hydraulic power to both extend and retract. A simple way to tell the cylinders apart is by looking at the number of ports. A Single Acting cylinder will have one port for the connection of a hydraulic cylinders Hydraulic Hose Fittings A Double Acting cylinder will have TWO ports.
