Bellows cylinders – powerful, dynamic and highly resistant

Bellows cylinders are ideal for short strokes and large forces. They work without mechanical friction surfaces that move against each other – rendering seals and lubricants unnecessary. As a result, they are virtually wear and maintenance-free. With their robust design and high-strength materials, bellows cylinders can be used under the toughest operating conditions.

Complete pneumatic solutions from a single source

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.

Four bellows cylinder series cover every option for a wide variety of applications

Well-armed: Our bellows cylinders are available in many sizes and version, as single, double, and triple bellows. Different rubber qualities cover a large range of temperatures and ensure the required chemical resistance. And their suitability for use with angular movements and axial offsets opens up additional fields of application. Depending on the series, tilt angles up to 30° and an offset of up to 30 mm are possible.

  • Most comprehensive product range on the market
  • Forces of 8.2 kN to 390 kN possible
  • Stroke lengths from 15 mm to 680 mm
  • Bellow diameters from 60 mm to 950 mm
  • Tested safety up to 24 bar
  • Extremely long service life, in part up to 12 x longer than competitive products
  • Zertifiziert nach REACH und Labs & ROHS
  • Configuration for potentially explosive areas (ATEX)

The bellow cylinders series

BCP – Bellows cylinder with plate

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).

BCC – Bellows cylinder combined (rings & plates)

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

- BCC Ø 8-16 inch (threaded bolt): galvanized steel connectors, bellows made of NR elastomer

BCR – Bellows cylinder with ring

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.

BRB – Bellow rolling lobe actuators

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.

Wherever robustness is in demand, bellows cylinders have what it takes

Be it high temperatures, dust, dirt, or mud – bellows cylinders are not easily intimidated. They’re used to working reliably and persevering even under heavy loads and adverse operating conditions.
Their extreme service life, comparatively low investment costs, and nearly maintenance-free continuous operation make application solutions with bellows cylinders particularly cost-efficient. Our bellows cylinders are used in many different industries, mainly for two purposes:

  • For short, powerful strokes with limited installation space
  • For vibration, oscillation and acoustic isolation

Our wide range of products and equipment features guarantee high machine design flexibility so you can be sure to find the right solution for your application.
