PNEUMATIC CYLINDERS
The rodless pneumatic cylinder
A traditional pneumatic cylinder uses a piston rod to move loads, while a rodless pneumatic cylinder transports the load along the piston. This allows the same stroke length in less space, which is particularly advantageous in confined working environments. In addition, the anti-rotation piston ensures that the load always remains in the same position, which increases precision and reliability. Rodless cylinders are ideal for applications where space saving and precise movements are required. Their field of application ranges from automation technology to industrial production processes. Discover the advantages and possible applications of rodless pneumatic cylinders for your specific requirements and optimize your work processes to be more efficient and space-saving.
Thanks to our production in Germany, we offer short delivery times:
2-4 working days as standard, regardless of series, diameter or stroke. If required, we can assemble any cylinder within 24 hours - at no extra charge!
PL - THE CLASSIC
- Equal forces in both directions
- Direct force output, secured against twisting
- Piston optionally with or without magnet
- Halved installation length - space-saving
- Extreme stroke length up to 5700 mm
- triple air connection, end position damping on both sides, adjustable
- High accelerations and speeds
- High degree of design freedom
- Operation with geolated or ungeolated air
- 3-stage steaming characteristics to protect the steam and load system
- Can be used in EX areas - ATEX
The cylinder tube is axially slotted throughout. Power is transmitted via a load coupling, which is attached to the piston shaft; the latter is designed in such a way that a web passing through the tube slot connects the inner part of the piston shaft to the outer part.

How a rodless pneumatic cylinder with slotted tube works
A rodless pneumatic cylinder with a slotted tube differs from conventional cylinders due to its special design. The cylinder tube is slotted along its length, which enables a direct connection between the piston and the external load.
Here is a brief description of how it works:
- Piston movement: Compressed air is fed into the cylinder, which moves the piston. The piston is designed to slide back and forth within the slotted cylinder tube.
- Load transmission: The piston is connected to a slide unit that moves along the outside of the cylinder. This connection is made through the slot in the cylinder barrel.
- Sealing system: The slot in the cylinder barrel is covered with a flexible sealing strip that moves with the piston. This sealing strip prevents compressed air from escaping and at the same time ensures that the piston slides smoothly.
Advantages of a rodless pneumatic cylinder with a slotted tube
- Space saving: Without a piston rod extending beyond the cylinder, less space is required, making it easier to integrate into compact systems.
- Longer stroke lengths: These cylinders can provide long strokes without the entire cylinder having to exceed the length of the stroke. This is particularly useful in applications where space is limited.
- Direct load transfer: The slot in the cylinder barrel allows the load to be connected directly to the piston, resulting in more precise and efficient power transmission.
- Anti-rotation piston: The carriage unit and piston are often designed to prevent the load from rotating. This ensures smooth movement and high precision.
- Reduced maintenance: The design without a piston rod and the use of a flexible sealing strip result in fewer moving parts and therefore less maintenance.
- Flexibility and versatility: These cylinders can be used in a wide range of applications, from automation technology to specialized production processes. They are ideal for situations where precise movements and compact design are required.
- High repeatability: Thanks to the direct and stable connection between piston and load, these cylinders offer high repeatability and reliability during repeated movements.
In summary, rodless pneumatic cylinders with a slotted tube offer a space-saving, precise and low-maintenance solution for a wide range of industrial applications.
