What are pneumatic cylinders?
Pneumatic cylinders (also called pneumatic actuators ) are mechanical devices that transform the energy of compressed air into linear motion.
Thanks to their simple and efficient design, they are the heart of industrial automation systems, enabling tasks such as lifting, pushing, pressing, or holding objects with precision and safety.
When compressed air enters the cylinder, it pushes a plunger, or piston , generating a force that translates into displacement. Depending on the type of cylinder, this movement can occur in one or both directions.
Types of pneumatic cylinders
At Disumtec, we have a technical catalog with the main types of pneumatic cylinders, compatible with the most common brands and standards on the market.
- Single-acting pneumatic cylinders
They use compressed air to move the piston in one direction. The return is achieved by a spring or external force. They are ideal for clamping applications, light lifting, or repetitive movements where the return does not require additional force.
- Double-acting pneumatic cylinders
Compressed air acts on both ends of the piston, allowing for controlled extension and retraction . They offer greater power, speed, and precision, making them the most widely used in industrial automation.
- Compact and guided cylinders
Designed for tight spaces, compact models allow direct mounting on machinery with limited space. Guided models incorporate additional axes that ensure stability during horizontal or vertical movements.
- ISO 6432 and ISO 15552 cylinders
They comply with international standards that ensure compatibility with various accessories and manufacturers (SMC, Festo, Norgren, Parker, etc.). They are a safe option for modular installations and rapid maintenance.
Key factors for choosing a pneumatic cylinder
Selecting the right cylinder directly influences the productivity and durability of the system.
Before purchasing, it is advisable to consider the following technical parameters:
- Diameter (Ø) : Defines the force the cylinder can generate. A larger diameter produces more thrust.
- Stroke (mm) : total distance traveled by the stem.
- Force (N) : depends on the diameter and working air pressure.
- Working pressure : normally between 1 and 10 bar.
- Mounting type : flange, pivot, foot or clamp.
- Travel speed : adjustable by flow valves.
- Work environment : conditions of temperature, humidity or exposure to corrosive agents.
Our technical team can advise you on choosing the most suitable cylinder based on load, speed, and industrial application.
Applications of pneumatic cylinders
Pneumatic cylinders are essential elements in thousands of automation processes.
Among its most common applications are:
- Assembly lines and automated production
- Packaging and labeling systems
- Industrial robotics and parts handling
- Pneumatic presses and clamping tools
- Automotive, food and pharmaceutical industries
- Opening, lifting or moving systems in special machinery
Their low energy consumption, reliability, and easy maintenance make them an economical and versatile option compared to hydraulic or electric solutions.

Maintenance and useful life
To prolong the life of a pneumatic cylinder, it is essential to use clean, dry and lubricated compressed air .
Air with impurities can damage seals and stems, generating pressure losses.
It is recommended to periodically review:
- Condition of gaskets and seals.
- Stem alignment.
- Correct lubrication of the system.
Proper maintenance reduces downtime and improves overall facility performance.
Frequently Asked Questions (FAQ)
What is the difference between a single-acting and double-acting pneumatic cylinder?
The single-acting type uses compressed air in only one direction, with spring return.
The double-acting uses air in both directions, allowing greater control and power.
How to calculate the force of a pneumatic cylinder?
Multiplying the working pressure (in bar) by the effective area of the piston.
For example, at 6 bar and Ø 50 mm, the approximate force is 1,177 N.
Where to buy pneumatic cylinders at the best price?
