What Is a Pneumatic Cylinder?
A pneumatic cylinder — also called an air cylinder or pneumatic piston — turns compressed-air pressure into straight-line motion. It consists of a tube, a piston with seals, a piston rod and two end caps with air ports. In a double-acting cylinder air drives the piston in both directions; a single-acting cylinder uses air in one direction and a spring to return.
Because compressed air is available in almost every factory, pneumatic cylinders are the most common actuators in packaging, food processing, textile, automotive assembly and robotics. They are fast, clean and easy to control with standard valves and, with a magnetic piston, their position can be read by sensors mounted on the tube.

Formula: F = p × A (1 bar = 0.1 N/mm²). Pull force is lower because the rod area is subtracted. Size the cylinder for 1.5–2 × the required force in dynamic applications. Try the pneumatic cylinder force calculator for any bore and pressure.
Air Consumption
| Bore | Litres per double stroke | L/min at 10 cycles/min |
|---|---|---|
| Ø32 mm | 1.11 | 11.1 |
| Ø40 mm | 1.74 | 17.4 |
| Ø50 mm | 2.72 | 27.2 |
| Ø63 mm | 4.32 | 43.2 |

| Ø100 mm | 10.87 | 108.7 |
| Ø125 mm | 16.99 | 169.9 |
Values ignore the rod volume and hose dead volume, so they are slightly conservative for compressor sizing. Multiply linearly for other strokes and cycle rates.
ISO 15552 or CETOP?
Choose ISO 15552 when cylinders must be interchangeable with other manufacturers’ ISO cylinders or carry position sensors; choose the aluminium CETOP PAG series for economical, lightweight machines, and the steel PNS series for dusty, humid or impact-prone environments and very large bores.
Supplying Saudi Arabia, Iraq and the Gulf Region
Fenitsa ships pneumatic cylinders to customers in Saudi Arabia and Iraq and can supply other Gulf markets from Türkiye. Road transport through Türkiye’s southern border crossings and sea freight via Mersin and İskenderun are the usual routes; the choice depends on weight, urgency and destination.
Quotations state price, production lead time and the agreed Incoterm (for example EXW, FCA, CPT or CIF). Shipments are packed for export with plugged ports and protected rods, and commercial invoice, packing list and certificate of origin are prepared with each order.
Pneumatic Cylinders – FAQ
What is a pneumatic cylinder?
A pneumatic (air) cylinder converts compressed-air pressure into linear motion. Air entering one side of the piston pushes it and the rod out; in a double-acting cylinder air on the other side pulls it back. Pneumatic cylinders are fast, clean and simple, which makes them the standard actuator in factory automation.
How much force does a pneumatic cylinder produce?
Force equals pressure times piston area. At 6 bar (87 psi) a Ø50 mm cylinder pushes about 1,178 N (120 kgf) and a Ø100 mm cylinder about 4,712 N (481 kgf). Real force is roughly 10 % lower because of friction.
What is the difference between a pneumatic cylinder and a hydraulic cylinder?
Pneumatic cylinders run on compressed air at typically 6–10 bar: fast, clean and inexpensive, but limited in force and less precise under varying loads. Hydraulic cylinders use oil at 100–250 bar or more, producing far higher force with stiff, controllable motion.
What does ISO 15552 mean?
ISO 15552 standardises the mounting dimensions of pneumatic cylinders from Ø32 to Ø320 mm, so ISO cylinders from different manufacturers fit the same mountings. Fenitsa’s FMY series is built to ISO 15552.
Can pneumatic cylinders be used in food processing?
Yes — pneumatic actuators are widely used in food and beverage lines because they are clean and simple. For direct food contact or wash-down areas, specify the environment when you ask for a quotation so that seals, surface finish and lubrication can be selected accordingly.
How do I calculate air consumption?
Air per double stroke ≈ (piston area × stroke + annulus area × stroke) × (p + 1.013) / 1.013. Multiply by cycles per minute to get free-air consumption in litres per minute.
