What is pneumatic actuator?
Pneumatic actuators are often considered to be the most cost-effective and simplest of all actuators. Pneumatic linear actuators function using compressed air to create movement, either by extending and retracting a piston or, more rarely, using a carriage that runs on a driveway or a cylindrical tube. The retraction of the piston is either done with a spring or by supplying fluid from the other end.

Following are the usual components that are part of the functioning of an actuator: 1 Power source: This provides the energy input that is necessary to drive the actuator. These are often electric or fluid in nature in the industrial sectors. 2 Power converter: The role of the power converter is to supply power from the source to the actuator in accordance with the measurements set by the controller. Hydraulic proportional valves and electrical inverters are examples of power converters in industrial systems. 3 Actuator: The actual device that converts the supplied energy to mechanical force. 4 Mechanical load: The energy converted by the actuator is usually used to make a mechanical device function. The mechanical load refers to this mechanical system that is being driven by the actuator. 5 Controller: A controller ensures that the system functions seamlessly with the appropriate input quantities and other setpoints decided by an operator.
Why do hydraulic actuators have pistons?
This is because liquids are almost incompressible. Single-acting hydraulic actuators have pistons that can move in just one direction and a spring is needed for reverse motion. A double-acting hydraulic actuator applies pressure at both ends to facilitate similar movement from both sides.
