The Easylift® System

The easylift® system is based on the “Lego-modular system”

Advantage:

There are an infinite number of off the shelf component combinations. This allows you to pick and choose from the most comprehensive product line available. You will have a “plug and play” solution with the shortest lead-time in the industry

What is possible:
Force:
7-12,000 N
Stroke:
10-1000 mm
Diameter 
cylinder/piston rod:
3/8 – 30/70
Model:
Standard
with scraper (protection if against wood chips or other rough dirt)
with covertube, -40°C to +60°C (protection against shocks, scratches and dirt)
with neutral labels
with valve inside the cylinder (pressure can be adjusted by using depressurizing screw)
with special seals for temperatures up to 200°
stainless steel version in 1,4404 (For special ranges of application, for example food industry or in outdoor areas)
with increased friction (The high static friction assures that the gas spring can be adjusted in every required position)
with lockable cover tube (When the stroke end is reached in push-out direction, the cover tube which is mounted around the piston rod, wedges in the guiding area of the gas spring)
Push-out speed/
damping
:
Gas springs are available with fast, normal, and slow extension speed. In regards to damping, you can choose between normal, increased, or no end damping. Note: Damping only becomes efficient if the gas spring is mounted with the piston rod showing downwards.

                                                                                                                                                Bansbach Recommendation for installation

                                                                                                                                                Just like other technical systems related to force development, the application of easylift gas springs requires knowledge and attention to some facts and figures. The essential criteria can be found on this page. Of course, when discussing your application, our consultants will go into detail about all the technical issues that are important to you. For our regular customers this is already routine.
                                                                                                                                                1. Within the ranges shown, you can select your optimum dimension yourself. The tolerance for the installation lengths is generally ± 2.5 mm, within a series production a manufacturing tolerance of max. ± 1 mm applies. For high demands on durability and stability, please avoid the combination: small diameter + long stroke + high force.

                                                                                                                                                2. Damping characteristics can generate vibrations that find a resonant body in the application, causing noise. Small changes to the installation, fasteners or tuning can remedy the situation.

                                                                                                                                                3. Bansbach gas springs have been designed and tested for the highest requirements and greatest possible reliability. Installation recommendations and our comprehensive advice will support you in the selection of your individual gas springs.

                                                                                                                                                  But: The suitability test for the respective application is always the responsibility of the user! Products which are unsuitable for the application and defective products must not be used. We therefore exclude any liability for the functionality and service life of your end product.

                                                                                                                                                4. Bansbach gas springs are manufactured to order – from mostly stock components. Cancellation, subsequent modification, exchange or return is therefore not possible.

                                                                                                                                                5. If gas springs are sent in for detailed inspection, this constitutes consent to the destruction of this part, and the right of ownership thereby expires. Return of individual components is not possible. If necessary, mark submissions with e.g. “For functional test and with request for return”. If there is no objection, gas springs sent in will be disposed of 1 week after notification of the test result.

                                                                                                                                                  As a general rule: For unjustified complaints we reserve the right to charge a lump sum or the actual costs for processing and disposal.

                                                                                                                                                6. Warranty claims expire in principle no later than 1 year after the date of manufacture of the gas spring. Manufacturing defects or quality defects in the gas spring can be detected immediately. If you are not satisfied with the delivered quality of the gas spring for a particular reason, please return it immediately. Please enclose the reason and an original copy of the invoice!

                                                                                                                                                7. Bansbach gas springs can be stored in any position. Pressure loss of the gas spring due to long storage is not to be expected. No negative empirical values are available. However, sticking effects can occur, which require a higher effort when the gas spring is actuated for the first time (breakaway force).

                                                                                                                                                8. The piston rod must be protected from impact, scratches and contamination – especially paint application. The cylinder tube must not be deformed. Damage to the surface will destroy the gas spring sealing system.

                                                                                                                                                9. Gas springs are maintenance-free. Do not grease or oil the piston rod.

                                                                                                                                                10. If gas springs are damaged visibly (broken or deformed connecting parts, bended piston rod, dented cylinder) due to external cause (accident, collision, extreme overloading,…) the pressure has to be released before the gas spring is being dismantled or used.

                                                                                                                                                  Please note our disposal and recycling instructions!

                                                                                                                                                11. Gas springs should not be exposed to any tilting or sideforces during operation. If this is unavoid able, please check the installation and use suitable connecting parts.

                                                                                                                                                12. Gas springs should be installed with the piston rod downwards. This position ensures the best damping effect. Only Bansbach gas springs include an integrated grease chamber which allows different directions of installation.

All gas springs are labeled with the warning „Do not open, high pressure“, the part number and the production date. If these dates are unreadable (removed, painting of the gas springs or any other influences) we refuse the liability for damages which result from this fact. Warranties aren’t possible anymore.

                                                                                                                                                15. Disposal / recycling: Gas springs are mainly made of metal and can be recycled. However, the gas springs must be depressurised beforehand. Please request our disposal instructions for gas springs.

                                                                                                                                                16. Gas springs are filled with pure nitrogen. Nitrogen is an inert gas, does not burn, does not explode and is not toxic. However: gas springs have a very high internal pressure (up to approx. 300 bar). Gas springs must never be opened without instructions!

                                                                                                                                                17. Bansbach gas springs can be used at ambient temperatures from -30℃ to +80℃. For other temperature ranges (down to -55℃ or up to +200℃) special seal sets are available. For low-temperature ranges, detailed coordination of the requirements is necessary. The ambient temperature has an influence on the gas spring characteristics. Changes in extension force as well as damping characteristics are to be expected and should be tested in advance under application conditions. Do not overheat gas springs or place them in an open fire! Other environmental conditions can also have a significant influence on the service life. Please take protective measures into consideration.

                                                                                                                                                In this case, the damping is not effected via the nozzle, as is the case with conventional gas springs, but is controlled by the groove in the cylinder. This results in many advantages: The damping in this variant has an effect in every installation position. Whether horizontally or with piston rod upwards – the damping characteristic is always the same.

                                                                                                                                                The damping intensity and characteristic can also be adapted more precisely to customer requirements. A very smooth transition into the damping is possible and thus spares the construction additionally.

                                                                                                                                                The dynamic groove is available for the cylinder diameters 15, 19 and 22. The groove is designed so that the damping characteristics correspond to the individual requirements of the customer.

                                                                                                                                                  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 do I find my personal contact person?

                                                                                                                                                  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.

                                                                                                                                                  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.
