Gas Springs: Basic Recommendations
• Do use standard gas springs rod down.
• If springs are to be stored prior to use, the spring should be stored rod down to lubricate the seal.
• Do try to use ball joints to help avoid side load forces. If eye (clevises) are used ensure a sloppy fit to allow lateral movement.
• Do ensure that the end fittings are in line so that side load forces are not applied as a result of misalignment.
• Do try to use shorter springs close to the hinge rather thanlong stroke springs away from the hinge.
• Do provide physical stops to limit the spring’s extremes. i.e. ensure that undue force is not applied to over compress or over extend the spring.
• Ensure the gas spring’s end fittings are fully screwed home.
• Where ball joints are used ensure the ball stud is flush with the surface and tightened.
• Do not scratch, dent, chip, bend or paint the rod.
• Do not puncture or incinerate. IGS provides a disposal service at minimal cost.
• Do not lubricate the gas spring.
• Do not cycle more than 15 times per minute.
• Under no circumstances attempt to regas a spring. This is an extremely hazardous operation.
• Do not allow external objects to exert side load forces on the gas spring or on the end fittings.
HEALTH & SAFETY
When gas springs are fitted to support loads where people are in danger should the load fall, a locking shroud should be employed. In addition, care must be exercised with regard to mounting position strength and end fitting suitability. It is critical to ensure that the end fittings are correctly installed both in the housing and to the spring to avoid additional loading on the fittings during use.
Gas Springs: Usage Guideline
1. Mount and dismount gas springs according to safety guidelines. To achieve long-life expectancy with reduced fatigue strength, employ sound mounting practices.
2. If gas springs are fitted in applications where failure means risk of health or life, we recommend using additional locking
mechanisms. This is a customer responsibility.
3. In FOOD or MEDICAL settings, request food-grade lubricating oils in place of industrial-grade hydraulic fluids, as minor quantities of fluid may leak from gas springs and should not come in contact with food or similar products or with subsoil water.
4. Allow for movement in joints. If the mount is subject to vibration, fittings must be secured.
5. Avoid side loading of gas springs. Long strokes may require additional support to avoid bending and tilting. Avoid non-axial forces.
6. Minor damage, corrosion or paint residue on the shaft may damage the unit’s seal and result in rapid failure. Any product change, adjustment or repair through any third party, without written consent from TURKAS will void any warranty or guarantee.
7. Unless specifically designed for tension loads, gas springs must not be loaded with traction forces.
8. Do not extend or retract gas springs beyond their design specifications. Gas springs are not to be used as a dead stop.
9. Use unit only within a temperature range of -40°F to 300°F (-40°C to 148°C). Contact TURKAS if intended use exceeds this range. Do not heat above 300°F (148°C).
10. TURKAS does not guarantee applications where proposals or drawings do not include parameters or conditions of use. In general, all orders must indicate if springs are used under normal conditions, -40°F to 300°F (-40°C to 148°C), or in environments that exceed these conditions (eg: water steam >300°F (148°C), chemicals, detergents, etc.).
11. Test gas springs after installation. TURKAS cannot simulate or anticipate the complete range of situations where our products may be used.
12. Avoid high accelerations or velocities during extension or compression as it could overload the unit.
13. Store gas springs in a shaft-down position to ensure lubrication of seal.
14. For horizontal use, specify TURKAS internal floated piston bearing with oil chamber.
15. Mount non-reservoir gas springs shaft-down, as they remain mostly in a static position.
