Bellow cylinders are ideally suited for short strokes and great force. They operate without moving mechanical friction points – eliminating the need for seals and lubricants. This makes them practically maintenance and wear-free.
Due to their robust structure and the use of high-strength materials, the bellows cylinders can be reliably used under even the most adverse working conditions. Bellows cylinders – powerful, dynamic and highly resistant.
Our bellows cylinder series offer you the most suitable bellows actuator for all individual tasks and operating conditions. But that is not all – as your specialists for pneumatic automation solutions we offer the suitable components as well, including expert consulting.
Excellently prepared – our bellows actuators are available in many sizes and versions – in single, double, or triple bellows variants. Various rubber qualities cover a large temperature range and guarantee the required resistance to chemicals. Their suitability for angled movements and axial offset offers a whole range of additional application areas. Depending on the series, they are suitable for angles of tilt of up to 30° and an offset of up to 30 mm.

Bellows actuators with firmly flanged stainless steel covers and bellows made of caoutchouc in the standard version.
The heat-resistant version is distinguished by bellows made of epichlorohydrin rubber (ECO) and the corrosion-resistant version by stainless steel covers (V2A).
Bellows cylinder with removable connectors. The customers have the option of replacing the rubber bellows themselves. Mounting via internal thread or threaded bolt.
BCC Ø 2-6 inch (internal thread): aluminum connectors, bellows made of CR elastomer
Bellows cylinder designed for very high forces with an aluminum mounting ring (no covers) and bellows made of NR elastomer. For direct mounting to suitable connection surfaces in the system. Therefore the connection geometry is freely configurable.
The inexpensive variations for lesser loads. Flexible rolling bellows cylinder with plastic connectors and bellows made of CR elastomer. Low weight, nearly constant force output over the stroke range.
Whether high temperatures, dust, dirt or mud – bellows actuators are not easily fazed. They are accustomed to functioning reliably and holding out for a long time even when handling heavy loads and in adverse operating conditions.
Their extremely long service life, the comparably low investment costs and their nearly maintenance-free continuous operation make application solutions with bellows actuators particularly economic. Our bellows actuators are primarily used by various sectors for two types of tasks:
For vibration, oscillation and acoustic isolation
The wide scope and range of equipment options guarantee great flexibility in machine designs.
Slide weight counterbalance on eccentric presses
Stationary agricultural sorting machine
Vibration isolation on mobile agricultural engineering, sprayer
Pneumatic lever
Vibration isolation on food industry kneading machine
