Nitrider® N-Series gas struts utilise the latest sealing technology* for a longer service life. The gas struts have a black coated body and durable rod with nitrided anti-corrosive surface specified at 144 hours resistance per ASTM-B117 salt spray test. They conform to most automotive requirements. A selection of end fittings is available for all sizes. Nitrider® N-Series gas struts are an ideal choice where exceptional quality, corrosion resistance and overall black appearance are important for your application.

Varilift® V-Series

Varilift® V-Series gas struts are the user adjustable version of the Nitrider® GAS strut. A bleed valve is fitted to enable the user to adjust the initial force of the strut. Each size is pressurized to the maximum vailable initial force for that range. Varilift® V-Series gas struts are ideal for prototyping new applications and those which cater for varying weights. They consist of a black coated body and durable rod with nitrided anti corrosive surface specified at 144 hours resistance per ASTM-B117 salt spray test. Varilift® V-Series gas struts conform to most automotive requirements.

Stainless Steel - S-Series

Stainless steel - S-Series gas struts are made from AISI 316 - (1.4401 - V4A) steel. They are suited to exposure to harsh enviromental conditions and will not rust or corrode and ideal for applications in the marine, food, and chemical industry. A selection of end fittings is available for all sizes.

Stainless Steel -Varilift® X-Series

Stainless steel - Varilift® V-Series gas struts are user adjustable version of the stainless steel gas strut. A bleed valve is fitted to enable the user to adjust the initial force of the strut. Each size is pressurised to the maximum available initial force for that range. Once installed, the adjustment may be made without removing the strut, saving considerable time and effort. Stainless steel - Varilift® V-Series gas struts are ideal for prototyping new applications and those which cater for varying weights.

* High tech sealing technology: >6mm rod diameter 2 cylinder sealings.

Test Force

The test force for a gas strut is shown in the diagram at point P1. The piston rod is pressed in up to 5 mm before the end stop, then the strut is relieved up to 5mm before total deflection and at this point (P1) the test force is measured.

Pressure

We can set the desired pressure in the cylinder ex-works. When selecting the cylinders in our shop, you may define the required pressure using a selection field. A gas strut with an individual force set once cannot be reset. For prototypes we have pressure-adjustable cylinders (V-series X-series) available where you can adjust the pressure yourself by means of a release valve. Dismantling the gas pressure strut for this is not necessary.

Exchange of a supplied Gas Strut

Once a Febrotec gas pressure spring has been delivered, it cannot be taken back, as the force individually selected by the customer means an individual pressure adjustment in the cylinder.

Maximum Permissable Temperature

The maximum permissible ambient temperature for gas struts is between -30°C and +80°C.

Service Life

The maximum service life of 30000 load cycles for the N and S series and is strongly dependent on environmental conditions such as dust and abrasive components of the ambient air. One can assume a power loss of approx. 10%.
