FAQ

It includes: tube, piston rod, sealing products, piston, bearing, o-ring, nitrogen gas, and hydraulic fluid.

Typically, high-pressure nitrogen gas is used.

It varies depending on product type and application, but is always high enough to generate force.

Usually between 50,000 to 100,000 km or up to 100,000 cycles, depending on conditions and quality.

Generally no. However, periodic leakage checks are recommended.

Performance may decrease. High temperatures increase internal pressure, affecting behavior.

Low temperatures increase fluid viscosity, potentially slowing movement.

No. Silent operation is expected. Noise may indicate internal wear or damage.

Through gas compression and resistance from internal hydraulic fluid.

By lab testing, road testing, and real-world usage feedback.

• Durability and cycle tests
• Pressure tests
• Stress simulations
• Leak and seal tests

All according to manufacturer quality standards.

Through long-term simulations and mechanical stress cycles.

Using special equipment to measure internal gas pressure under compression.

Yes. Temperature fluctuations impact pressure and oil viscosity.

• Proper installation
• Using correct mounting angle
• Regular inspection
• Avoiding contamination

In standard temperatures, proper orientation, and with clean environment.

• Gas springs: smoother, quieter, maintenance-free
• Hydraulic: better control, heavier
• Coil springs: simpler, mechanical, less adaptive

Gas springs offer better price-performance in most use cases.

Yes, even above 90°, but optimal performance is with rod pointing down at angles less than 60° from vertical.

Generally high, due to combined gas-hydraulic resistance.

Always follow the manufacturer’s instructions. Proper orientation and alignment are critical.

• Rod must point downwards (below 60° from vertical) • Correct pressure rating • Suitable mounting hardware • Use ball joints to avoid lateral forces • Avoid bending, scratching, or misaligning the rod

• Wrench set • Torque wrench • Sometimes, special mounting brackets or clevises depending on the application

It varies based on application and hardware type.

No. Correct gas spring must be selected based on vehicle or equipment model.

Yes. Correct end fittings, brackets, and sometimes custom hardware are needed.

Store with the rod pointing downward to keep the seal lubricated.

Gas springs use metal and plastic connectors, such as: Metal End Fittings • Ball joint connectors: allow multi-axis movement • Metal clevis/fork: secure U-shaped attachments • Metal brackets: for firm angle mounting • Metal eyelet heads: for pin-type connections Plastic End Fittings • Conical tips: tight fit into matching holes • Threaded mounts: allow screwing directly into application surface

Only with reservoir-equipped or fully damped gas springs. Otherwise, damping will not work properly, and lifespan may shorten.

• Ensures oil contacts the main seal • Prevents seal drying and loss of damping at end of stroke • Enhances lubrication and product life

• Ensures oil contacts the main seal • Prevents seal drying and loss of damping at end of stroke • Enhances lubrication and product life Mounting “Do’s” • Use standard gas springs with rod pointing down • Use ball joints to absorb misalignments • Install physical stops to prevent over-compression • Ensure end fittings are fully threaded • Mount closer to the hinge for better force transfer • Align ball joint stems and keep them tight • If using clevis, ensure it’s loose enough to move laterally Mounting “Don’ts” • Do not lubricate the gas spring externally • Do not scratch, bend, paint, or notch the rod • Do not puncture, weld, or burn gas springs • Do not cycle more than 15 times per minute • Do not attempt to refill or re-gas • Do not apply lateral force via external objects • Do not misalign or over-tighten end fittings

Yes, they are safe when installed and used correctly. Misuse may cause serious accidents.

• Always follow installation instructions
• Do not exceed force or temperature limits
• Avoid modifying or opening the spring
• Prevent side loads or impacts on the rod

No, not under normal conditions. But refilling, heating, cutting, or welding can cause explosions.

They must comply with international and local standards, verified through stress and performance tests.

• Pressure resistance
• Leak testing
• Cyclic performance
• Environmental stress simulation

• Do not refill or adjust gas pressure
• Never disassemble, cut, weld, or heat the spring
• Do not scratch or bend the rod
• Do not paint the rod or block its movement
• Never cycle the spring more than 15 times per minute
• Avoid contact with abrasive particles, steam, or chemicals
• Do not allow welding spatter or metal fragments to stick on the rod
• Avoid uneven loads or lateral forces

• Leakage
• Pressure loss
• Mechanical wear
• Noise or abnormal movement

• Visual inspection for oil stains
• Performance drop
• Unusual noises during operation

• Soft spring movement
• Delayed response
• Reduced lift or support force

• Replace the spring
• Seek professional inspection
• Do not attempt to repair unless designed for it

Rarely. In most cases, replacement is safer and more cost-effective.

Symptom	Possible Cause	Solution
Oil leakage	Damaged seal or wear	Replace the gas spring
Weak force	Internal pressure drop	Replace the gas spring
Noisy operation	Worn parts, air bubbles	Inspect or replace if needed
Spring not extending	Bent rod, blocked path	Replace unit, inspect mounting area
Uneven operation	Misalignment or incorrect mounting	Reinstall correctly

How long can gas springs be used?
Up to 100,000 cycles under proper use. Average is 50,000–100,000 km in automotive usage.
