What Are Pneumatic Cylinder Parts?

Pneumatic cylinders are actuators that convert the energy of compressed air into linear motion. Their various structural components, due to their high interchangeability and customizability, serve as highly flexible solutions in modern automation systems.

Pneumatic cylinder parts can also be referred to as a cylinder assembly kit,including cylinder kits,seal kits and mounting brackets.

Different Types of Pneumatic Cylinder Parts

Below is a list of some basic cylinder components and their names.

Cylinder tube

The main body of the cylinder, also internal parts of the cylinder,designed to contain the piston's motion and withstand internal pressure while ensuring smooth and sealed operation.The cylinder barrel must be resistant to corrosion from water, water vapor, most chemicals, and acidic or alkaline environments, while also possessing sufficient strength to ensure the proper functioning of its internal components. 

To achieve lightweight design for the cylinder, aluminum material should be selected for the cylinder barrel, as it can significantly reduce the overall weight of the equipment.

Piston Rod

Connects to the piston and extends outside the cylinder, transmitting linear motion and force to external mechanisms.There are three piston rod types provided by fokca.

#45 Carbon Steel Piston Rod

The surface is typically polished and chrome-plated to improve wear resistance and corrosion resistance. Suitable for hydraulic or pneumatic equipment subjected to general mechanical loads and impacts. It is a commonly used economical piston rod due to its lower cost.

Stainless Steel Piston Rod

Made of 304 or 316 stainless steel, with a smooth surface and strong resistance to oxidation and chemical corrosion, suitable for humid or corrosive environments.

Stainless Steel Hollow Piston Rod

Made of stainless steel, but with a hollow piston rod structure. Lighter than a solid rod, reducing system inertia and facilitating high-speed operation; the hollow structure also facilitates internal wiring or fluid passages.

Piston

Located inside the cylinder, it moves back and forth under air pressure and separates the cylinder into two working chambers using seals.

End caps

Mounted at both ends of the cylinder, they close the cylinder tube and provide air ports, guiding, and cushioning functions.

Rod guide

Installed inside the front end cap, it supports and guides the piston rod, reduces side loads, and protects the seals to extend cylinder life.

Tie Rod

Tie Rod is a critical component in the structure of a tie-rod cylinder, primarily used to maintain the cylinder's overall structural stability and ensure reliable sealing.
