The dynamic that provides movement and drive
Pneumatic cylinders are powerful components of a pneumatic drive system and have been used for almost 70 years in many industrial sectors for various drive tasks.
What is a pneumatic cylinder?
In pneumatic systems, pneumatic energy (compressed air) is converted into mechanical energy (movement). This energy is mainly converted by pneumatic cylinders. An actuator controls the pneumatic cylinder, which is responsible for the linear movement of a mechanism or system.
Simply put, a pneumatic cylinder consists of a cylinder tube, a base cover and a cylinder head, also known as a bearing cover. The tube contains a piston, a piston rod and various seals and compressed air connections. A guide ring with a seal and a wiper is located at the outlet of the piston rod in the area of the bearing cover. This wiper prevents dirt from entering the cylinder tube.
The advantages of pneumatic cylinders
Where are pneumatic cylinders used?
Pneumatic cylinders often perform the functions of lifting, pushing, lowering, clamping, tightening, feeding and moulding in industrial processes and are used in many pneumatic applications:
Which variant should it be: single-acting or double-acting?
Single-acting pneumatic cylinders have an active compressed air connection and are only pressurised with compressed air from one side. The cylinder only ever works in one direction. A return spring ensures the retraction or extension movement of the piston rod in such cylinders.
Double-acting pneumatic cylinders are operated exclusively with compressed air. Both compressed air connections are therefore actively controlled. The piston rod movement is controlled by feeding compressed air into the cylinder from one side or the other. Pneumatic cylinders are usually equipped with end position damping. The speed of the piston is slowed down when it moves into the end position, thus preventing damage or impacts.
FAQs
Standard cylinders according to ISO 15552 offer a versatile solution with piston diameters from 32 mm to 320 mm. These working cylinders feature advanced pneumatic cushioning for improved performance. Thanks to the modular system, the wiper on the cylinder can be easily replaced. This ensures easy maintenance and low-maintenance operation.
In addition to standard cylinders to ISO 15552, TRI-MATIC's product range also includes miniature cylinders to ISO 6432. The cover and base are adapted so that they can also be used where space is limited.
Micro cylinders are ultra-compact motorised lifting cylinders and are used for short lifting distances, in press assembly or for lifting and lowering.
Compact cylinders from the CMPC series and short-stroke cylinders are pneumatic piston rod cylinders that can be used for a wide range of applications thanks to their compact design in confined spaces.
Stainless steel cylinders made of 1.4301 or 1.4401 stainless steel are characterised by their corrosion resistance in aggressive environments. All these different cylinders are available in various designs in the TRI-MATIC product programme.
Other types of pneumatic cylinders are
- Rodless cylinders,
- multi-position cylinders,
- tandem cylinders,
- telescopic cylinders,
- rotary cylinders and
- grippers.
All in all, pneumatic cylinders are powerful components of a pneumatic drive system. Our experts will be happy to provide you with further information at any time. Contact us at +41 41 780 22 22 or info@tri-matic.ch.
