Air Cylinders

Pneumatic cylinders (sometime known as air cylinders) are mechanical devices that use the force of compressed gas to generate force in a reciprocating linear motion. As with In hydraulic cylinders, something forces a piston to move in the desired direction. The piston is a disk or cylinder, and the piston rod transfers the force it develops to the object to be moved. Engineers sometimes prefer to use tires because they are quieter, cleaner and Not
big are plenty of room for liquid storage. Because the working liquid is a gas, leaks from a pneumatic cylinder will not drip or contaminate the surrounding area, making pneumatics desirable where cleanliness is a requirement. 

How do Air Cylinder/Actuators work?

The key components of a pneumatic actuator include an end cap, piston, piston rod, cylinder, wiper seal, and cushioning sleeve and seal. A single-acting pneumatic actuator can be operated with a button in a simple circuit. When this button is pressed, air moves the piston rod out.

Pneumatic systems use compressed air to create rotary or linear mechanical motion and force applications that "work". The pneumatic actuator uses compressed air to act on a piston inside the cylinder to create the required movement, e.g. holding or moving a load along a linear path. The end use can be as diverse as a specific piece of equipment, such as a gripper or clamp for a suction cup used to handle glass.

A single-acting pneumatic cylinder or actuator has a port where air enters and then pushes the plunger in one direction. The piston is then returned to its original position by a spring. These air cylinders have limited stroke lengths, making them useful for slower operations. They also use less air, providing optimal efficiency and lower running costs for the A double-acting pneumatic cylinder or actuator has two ports that allow pressure to be applied to pull the piston in the opposite direction to that created by the first port, also known as a Single lift and on external lift.

In general, the larger the inside diameter of the cylinder, the greater the power output.

Key factors when choosing a pneumatic cylinder or actuator:

• Type of movement: Which pneumatic actuator or cylinder you need depends on whether they go in a rotary or linear motion.
• Pressure and flow requirements: Think about what you want from the cylinder or pneumatic actuator. This also includes other necessary components; improper sizing can affect performance.
• Environment: Due to
  corrosion resistance developments, pneumatic cylinders and actuators can operate in extreme temperatures. Stainless steel cylinders or actuators are also available.

• Special features: If you are looking to save energy, consider using an integrated pneumatic cylinder or actuator. Also ensure that the actuator or cylinder is the correct size and suitable for the expected service.
• Single-acting or double-acting: Pneumatic cylinders or actuators are generally classified into one of these. Both categories are divided into categories based on the type of application, the force or movement required, the size of the
  job, and the precision or control expected. In general, a pneumatic cylinder or actuator contains a piston and rod inside.
• Type depends on application: Various types of pneumatic cylinders or actuators are available, including rodless cylinders, round cylinders and compact cylinders.
