Single Acting vs. Double Acting
- - Single acting cylinders are economical and the simplest design. Hydraulic fluid enters through a port at one end of the cylinder, which then moves the piston to extend the rod. An external force returns the piston to its normal position and forces the hydraulic fluid back through the supply tubing to the fluid reservoir.
- - Double acting cylinders have a port at each end, supplied with hydraulic fluid for both the retraction and extension of the piston. They are used where an external force is not available to retract the piston or where high force is required in both directions of travel.
