FAQs - Frequently Asked Questions

We have also developed a series of FAQs for answers to the most common questions in the spring industry.

Which way up do I mount the gas spring?

Gas springs should be mounted so that the rod points down in the inactive state. This ensures that the internal guide and sealing system remains lubricated.

Which is the best type of end fitting?

Ball joints are best in avoiding side load forces. Such forces may lead to premature failure. If eye or clevises are to be used, ensure a clearance fit to allow lateral movement.

How do I know which P1 force to use?

Consider fitting a Varilift Gas Spring in order to find the correct working force. We will measure this and supply custom fixed force gas springs. Alternatively, complete the Engineering Worksheet (see special springs section) and we will calculate it for you.

Are alternative sizes and pressures available?

Standard sizes are available in any pressure within the minimum and maximum for the range. Custom sizes are also available, but may be subject to increased lead-time.

Should I provide a physical stop?

Physically limiting the extremes of the operating stroke will prevent damage occurring through excessive loading.

In what temperature range will gas springs operate?

Our gas springs are designed to operate between -30 C and +80 C.

What maintenance is required?

Gas springs are maintenance free. They do not require greasing or lubrication.

What if I only want the gas spring to operate infrequently?

Long periods between operation may result in loss of pressure or damage through dirt build up.

How should I store gas springs?

If storage is required, gas springs should be stored with the rod pointing down. Avoid the use of adhesive tapes, which may leave residue and result in damage to the seals.

What do I do if the gas spring loses pressure?

Do not attempt to dismantle the gas spring or refil with gas. This is a hazardous process. Contact us regarding your application, as an alternative mechanical solution may be possible.

How do I dispose of the gas spring?

Gas springs should be disposed of in an environmentally correct manner. Do not puncture or incinerate.
