Hydraulic and Pneumatic systems are similar in that they both use double/single acting cylinders to operate something - Be it an automatic door for pneumatics and other such trivial tasks, or JCBs with hydraulics. Another key similarity would be the way in which they work - they both take the easiest path where available and both use 3/2 valves. A major difference between them is the pressures involved, the output forces and the use of 4/3 (hydraulics) and 5/2 (pneumatics) to operate a double acting cylinder.

Single-acting devices consist of a large plunger, or piston, into which oil (or air in a pneumatic cylinder) is pumped.
If one takes a look at the schematic drawing of an auto-retract clamp and drill hydraulic circuit, one will see the single-acting clamp cylinder and quarter of an inch operator control valve. It also has double-acting work cylinder, as well as quarter inch air sequence valve.
Reciprocating compressors are either single- or double-acting. In single-acting machines the compression takes place on only one side of the piston; double-acting machines use both sides of the cylinder for compression.
The working pressure acts from one side in single acting actuators while in double acting actuators strokes generating by each side.

Yes, a double-acting cylinder can be used as a single-acting cylinder by only utilizing one side of the piston for movement. In this configuration, air or fluid is applied to one side to extend the rod, while the return is accomplished using a spring or gravity. However, this may limit the cylinder's performance and efficiency compared to its designed operation as a double-acting device. It's essential to consider the application requirements before making such a modification.
A single-acting cylinder operates by using fluid power to extend the piston, which is then retracted by an external force such as a spring or gravity. When fluid pressure is applied, it pushes against the piston rod to extend it, performing work in one direction. The return stroke is accomplished by the external force, as there is no fluid pressure acting in the opposite direction.
Reciprocating pumps will deliver fluid at high pressure (High Delivery Head).They are 'Self-priming' - No need to fill the cylinders before starting.
Baking powder is a single-acting leavening agent that reacts once it is mixed with liquid. Double-acting baking powder reacts twice, once when mixed with liquid and again when exposed to heat, providing a more consistent rise in baked goods.
A differential cylinder has a large piston that requires a greater amount of oil to displace the cylinder, thus allowing greater uniformity of force than a typical single-acting cylinder.
