Recommendations for Gas Springs
- Use standard gas springs rod-down, i.e. the spring should be mounted so that it spends most time in a rod-down position, within 60° of vertical, thus ensuring the seal stays lubricated. For tension springs the exact opposite is true, i.e. use rod-up. Once installed, test at least every three months.
- Try to use ball joints to help avoid side load forces. If eyes or fork clevises are used, ensure a loose fit to allow for lateral movement.
- Ensure that the end fittings are in line so that side load forces are not applied as a result of misalignment.
- Try to use shorter springs close to the hinge rather than longer stroke springs away from the hinge.
- Provide physical stops to limit the spring’s extremes - i.e. ensure that no undue force is applied, which might over compress or overextend the spring.
- Scratch, dent, chip, bend or paint the rod.
- Apply side loads.
- Attempt to recharge.
- Puncture or incinerate it.
- Lubricate it.
- Fast cycle it - typically no more than 3-4 times per minute.
When gas springs are fitted and safety is a key factor, special care should be exercised with regard to fitting suitability, mounting position strength and whether or not a secondary locking mechanism should be employed.
Store in rod-down condition, except for tension springs which should be stored rod-up.
