• How does a gas spring work?

Gas spring are self-contained ,pneumatic devices capable of producing very large forces (50N to 1800N) from a compacted piece. A typical gas spring consists of a shaft connected to a piston head,which moves within a cylinder.

The cylinder contains nitrogen at high pressure.The piston has an orifice which allows gas pressure to pass through and act equally on both sides. It is the pressure acting on the shaft cross-sectonal area which provides the spring its force.

  • Should a gas spring be mounted rod up or rod down?

Rod down is the preferred orientation for mounting a gas spring. Optimum design permits the support to be oriented rod down through its entire actuation.

  • How does temperature affect the life and performance of gas spring?

Temperature affects gas springs in two ways. As the temperature of the gas spring changes, the internal pressure also changes. As the internal pressure changes,so does the output force. The nominal force will change by approximately 3% for every 10°C change.

Very high or very low temperatures can adversely affect the gas spring’s ability to retain its gas charge. At very high temperatures,the permeability of the seal increases and gas molecules may diffuse through the seal more quickly. Usually, gas spring can support and perform reliably at temperatures ranging from -20°C to +80 °C

  • About The gas springs life cycle ?

• After 20,000 cycles of operation force drop should be 10% (Max) under Ambient Temp. condition. • Operting Temp. :-20° C To +80° C

  • What is the pressure in the gas springs?

It depends on the gas spring model and the extension force; it can be 150 bar or more.

  • Can the gas spring also be protected from gross contamination?

Yes, by using plastic protective caps in the Dimpling area, or conduits and bellows.

  • How much does a gas spring weight?

Depending on its length and diameter, a commercial gas spring weighs between 100 g and 500 g.

  • How are gas springs identified?

As a rule, gas springs are identified with safety instructions, material numbers (IDEAL number or customer number upon request), as well as the manufacturing date.

  • Which colors are available?

Gas springs are normally BLACK POWDER COATED, MOONGRAY. HC PLATED avaialable on request.

  • What length tolerances are typical?

This depends on the gas spring model, but typically it is +/- 3 mm.

  • What kind of noises do gas springs make?

Due to their gas or oil filling and the “speed control” function, gas springs can emit design-dependent flow sounds.

  • Who can I talk to about my problem; who will help me?

For contact info see the pages of the corresponding market segments.

  • What is the delivery time for brochure or catalog models?

Brochure models can usually be delivered within one week from receipt of order; the catalog only includes a small portion of all potential product variants.

  • Do the gas springs come only in the given length or force specifications, or are there “intermediate sizes”?

Gas springs can be varied with regard to many of their dimensions and extension forces.

  • What forces are available?

Depending on the model, normally between 50N and less than 1800 N.

  • What kind of end fittings are available?

Depending on the application, a variety of end fittings are available, such as plastic or metal fittings for ball studs or ball joint fittings, Iyelets, Forks Brkts

  • Do gas springs require any kind of maintenance?

No, gas springs are maintenance-free.
