Installation round cylinder

Lifting suction device – lifting at lightning speed with just one vacuum line!

Function:
  • When the vacuum is switched on, the piston rod extends
  • If the workpiece is touched by the suction cup, it is sucked in
  • Then the piston rod with the workpiece moves back to the starting position
  • As long as the vacuum is switched on, the workpiece is held on the piston rod
Accessories:
  •  Holder for position monitoring
  •  Magnetic sensors
  •  Push-in fittings and others
Advantages:
  • The cylinder is controlled exclusively by the vacuum – very easy!
  • A complex control is not required
  • The cylinder is only controlled by the vacuum and therefore only needs one supply line
  • Components with different heights can also be lifted within seconds
  • Very fast work thanks to extremely short cycle times
  • If the component is lost, the piston rod extends again immediately
  • Very flexible and versatile
Product characteristics:
  •  Stroke: 25mm (other on request)                     
  •  Force: up to 7N
  •  Vakuum connection: M5
  •  Suction connection: G1/8″
  •  Mounting connection: M8
  •  Anti-twist 

Rack and pinion drive

Product characteristics:
  • Diametre of the rack: 16 – 20 mm
  • Cylinder diametre: 63 – 100 mm  
  • Function: double operating 
  • Stroke length: up to 200 mm 
  • Force at 6 bar: 180 – 47 kg
  • Operating pressure: 6 – 10 bar
  • Temperature range: -20 °C – +80 °C

Transporting a medium through the piston rod

This product allows you to pull a medium (e.g. air, oil) through the center of the pneumatic, creating a vacuum. The suction process can be designated as continuously on, on only in extension, or on only in compression. This pneumatic is designed for filling or vacuum designs and not for standard pneumatic designs.
Please contact us and will find the right cylinder with transport medium for your application!
Product characteristics:
  • Piston rod diametre: 25 mm

  • Force at 6 bar: 75N
  • Operating pressure: 6 – 10 bar
  • Temperature range: -20°C – +80°C

Pneumatic cylinder with guided piston rod

The application of the piston rod allows for a controlled turn during the push-in and push-out movement. The degree of the turn movement can be specified according to the customer’s application. Depending on your application, you may also request the piston rod be secured against rotation.
Please contact us and we will find the perfect cylinder with guided piston rod for your application!
Product characteristics:
  • Piston rod diametre: 20 mm
  • Cylinder diametre: 50 mm  
  • Function: double operating 
  • Stroke length: up to 850 mm
  • Force at 6 bar: 110 kg
  • Operating pressure: 6 – 10 bar
  • Temperature range: -20°C – +80°C
  • Kind of mounting: flange and rotatable fastener

Compact cylinder

The compact cylinder is unique due to its small installation parameters, optimized by the disappearing piston rod. Despite its small size, loads up to 4,000kg can be lifted. The connecting parts have also been adapted to these parameters.
Contact us and we will find the suitable cylinder for your application
Product characteristics
  • Piston rod diametre: 30 – 50 mm
  • Cylinder diametre: up to 300 mm  
  • Function: single or double operating
  • Stroke length: 20 – 30 mm
  • Operating pressure: 6 bar
  • Temperature range: -20 °C  –  +80 °C
  • Kind of mounting: flange fastening

Mountable round cylinder

This cylinder is designed for compact installation. Due to the complete use of the piston rod, the entire length can be optimized. Despite compact mounting, larger strokes can be achieved by producing a telescopic version.
Please contact us and we will find the right cylinder for your application!
Product characteristics
  • Piston rod diametre: 25 mm
  • Cylinder diametre: 40 mm  
  • Function: double operating
  • Stroke length: up to 200 mm
  • Force at 6 bar: 110 kg
  • Operating pressure: 6 – 10 bar

FAQs

Are Bansbach gas springs ROHS compliant?

Yes, they are fully ROHS compliant and also meet all guidelines, export/import regulations and goals of other company programs that we are aware of.

Can a gas spring made to customer specifications be returned?

Bansbach gas springs are manufactured to order – from mostly stock components. Cancellation, exchange or return is therefore not possible.
In case of free delivery, we will gladly take over the disposal – without charge – for you.

Can gas springs be disposed of in household waste?

No, gas springs are mainly made of metal. Please observe our disposal instructions.

Can gas springs be used in the food industry?

With the high-quality stainless steel gas springs in V4A, the high requirements of the food industry are met. Food-grade oil (FDA oil) is optionally available.

Can the speed/damping of the gas spring be influenced?

By selecting the appropriate nozzle bore and oil viscosity, the speed and damping of the gas spring can be adapted to the application.

Do Bansbach gas springs have to be stored with the piston rod pointing downwards?

Bansbach gas springs can be stored in any position.

Does a gas spring need to be protected from dirt?

The piston rod must be protected against impact, scratches and contamination – especially paint application. Damage to the surface will destroy the sealing system. If necessary, a wiper or a protective tube should be provided.

Does a gas spring need to be serviced?

No, Bansbach gas springs are maintenance-free. The piston rod must not be greased or oiled.

How high can the internal pressure of a gas spring be?

Depending on the series and the desired extension force, this can be up to approx. 300 bar.

How much is the weight of a gas spring?

Due to the wide range of products, the weights vary greatly.

Diameter piston rod / cylinder:
Ø3/8; Ø4/12; Ø6/15; Ø6/19; Ø6/22; Ø8/19; Ø8/22

Weight
100 g – 500 g

———-
Diameter piston rod / cylinder:
Ø8/28; Ø10/22; Ø10/28; Ø12/28; Ø14/28

Weight
200 g – 1000 g

———-
Diameter piston rod / cylinder:
Ø16/28; Ø10/40; Ø12/40; Ø14/40; Ø20/40; Ø30/70

Weight
500 g – 8000 g

In which colors are Bansbach gas springs available?

The piston rod and the cylinder are supplied in black (standard).

On request, our cylinders are available in all RAL colors. Exception: stainless steel

In which temperature ranges can Bansbach gas springs be used?

For ambient temperatures from -30°C to +80°C.
For other temperature ranges (down to -55°C or up to +200°C) special seal sets are available.

Is it possible to repair a gas spring?

No, because it is a closed system that is under high pressure and must not be opened.

Is the extension force of the gas spring temperature-dependent?

For physical reasons, the extension force of the gas spring changes by approx. 3.3% per 10°C (base + 20°C).

What does the index number (e.g. – -001/100 N) at the end of the article designation of the gas spring mean?

This is a code assigned internally by Bansbach for unambiguous reproducibility of the gas spring.

What materials are Bansbach gas springs made of?

Gas springs consist of piston rod, cylinder tube, connecting parts, turned parts, seals, oil, grease and nitrogen. Piston rods and cylinder tubes are made of steel and are CeramPro® or powder coated in our company. Connecting parts and turned parts are made of lead-free steel or lead-free aluminum.

Seals, oils, greases do not contain substances that are on the list of critical or hazardous substances. Nitrogen is an inert gas that neither burns nor poses any other health hazards. Bansbach gas springs therefore comply with current and, as far as we know, planned laws and regulations.

They comply for example with the RoHS Directive, WEEE Directive, Directives 2003/11/EC, 2002/95/EC, 2002/96/EC. They are not covered by Directives 94/9/EC, 97/23/EC, and 98/37/EC, nor by UN 3164, TRGS 220, and UL 60601-1.

Verification that Bansbach gas springs in the end product comply with national or international laws and regulations remains the responsibility of our customers or the user.

What service life/running performance can I expect from a Bansbach gas spring?

On average, Bansbach gas springs are designed for 50,000 – 100,000 double strokes.
Depending on the design, installation and effective stroke, several 100,000 strokes can also be achieved.
For other products please contact us.

Which stroke lengths are possible for the gas springs?

Depending on the series and design of the gas spring, the stroke length can be freely selected between 10 mm and 1000 mm. Other variations possible, please contact us.
