0. when comparing single acting vs double acting hydraulic cylinders, the most visible difference is the number of couplers or connection ports. a single acting hydraulic cylinder includes just one port. this is where the hydraulic fluid enters and forces the plunger out in one direction. a double acting cylinder includes two ports. A single acting cylinder is the simplest type. hydraulic force can only be applied to the cylinder through its single port – typically to extend the plunger. this is returned to its starting position through the weight of the load, or by a return spring within the cylinder. above: single acting double acting and pull types of hydraulic cylinders.
Hydraulic cylinders are available in single acting and double acting configurations. a single acting cylinder uses hydraulic pressure to extend the plunger and a return spring to bring it back to the original position. a double acting cylinder uses hydraulic force to both lift and lower the plunger. this provides much more control and precision. Load return cylinders are hydraulically extended and retracted by the load or other external forces. simplex 3 way, 3 position suc o matic valve can draw hydraulic oil out of any single acting cylinder. in the retract position, the valve generates enough suction to fully retract any single acting load return cylinder automatically. A hydraulic cylinder with a hollow plunger allows for both pull and push forces. choose between single acting and double acting models, and cylinder bodies constructed in either high alloy steel or anodized aluminum. enerpac hollow cylinders available for sale fully comply to asme b30.1 (except brd rd series). In this video, we will explain the difference between a single acting hydraulic cylinder and a double acting hydraulic cylinder. find out more at sar.
