OEM Air Pneumatic Cylinder Kit Manufacturer

Industry Information

What are the components included in a pneumatic cylinder kit?

Cylinder Barrel: The cylinder barrel is the main body of the pneumatic cylinder, typically made of metal or sometimes composite materials. It provides the housing for the piston and other internal components.

Piston: The piston is a cylindrical component that moves back and forth inside the cylinder barrel. It is usually sealed with piston rings to maintain proper air pressure.

Rod: The rod is attached to the piston and extends outside the cylinder barrel. It transmits the force generated by the piston to the external load or mechanism.

End Caps: The end caps are attached to the cylinder barrel and provide mounting points for the cylinder. They also contain ports for air inlet and exhaust.

Seals: Seals are essential components that ensure proper sealing between the piston, rod, and cylinder barrel, preventing air leakage and maintaining the required pressure.

Mounting Hardware: Pneumatic cylinder kits often include various mounting hardware such as brackets, clevises, or trunnions to facilitate the installation and attachment of the cylinder to the desired location.

Mounting Accessories: Depending on the application, the kit may also include additional accessories such as mounting brackets, spacers, or pivot pins to adapt the cylinder to specific mounting configurations.

Fittings: Fittings are connectors used to link the pneumatic cylinder to the air supply system. These can include connectors, couplers, or adapters that allow for proper airflow into and out of the cylinder.

Fasteners: Kits may include screws, nuts, bolts, or other fasteners required for assembling the components of the cylinder and securing it to the intended application.

Optional Components: Depending on the specific application and requirements, a pneumatic cylinder kit may include additional components such as proximity sensors, flow controls, or cushioning devices to control the speed or provide smooth deceleration at the end of the cylinder stroke.

How does a pneumatic cylinder work?

Compressed Air Input: Compressed air is supplied to the cylinder through a port, usually located at one end of the cylinder. The air is typically stored in a separate compressed air system or generated by an air compressor.

Cylinder Barrel: The cylinder barrel is a hollow tube made of sturdy material, such as metal or reinforced plastic. It provides the housing for the other components and guides the movement of the piston and rod.

Piston and Seal: Inside the cylinder barrel, there is a piston that separates the cylinder into two chambers: the air supply side and the exhaust side.

Rod and Load Attachment: One end of the piston rod is connected to the piston, while the other end extends out of the cylinder through a seal. The rod provides a connection point for attaching loads or other mechanisms that need to be actuated by the cylinder's motion.

Control Valve: To control the direction and timing of the cylinder's motion, a control valve is used. The valve directs the flow of compressed air into either the supply side or the exhaust side of the cylinder, depending on the desired movement.

Air Supply and Exhaust: When compressed air is directed into the supply side of the cylinder, it pushes the piston along the cylinder barrel. This motion causes the rod to extend outward. On the other hand, when the control valve redirects the airflow to the exhaust side, the compressed air on the supply side is released, and the piston moves in the opposite direction, causing the rod to retract.

Repeat Motion: By controlling the flow of compressed air through the control valve, the cylinder can produce continuous back-and-forth linear motion. The speed and force of the cylinder can be adjusted by regulating the air pressure and the size of the cylinder.
