Hydraulic Gas Strut

Our hydraulic gas strut (also known as gas spring) is a high-performance elastic support component, filled with high-purity nitrogen in a sealed cylinder. It converts the pressure of compressed gas into stable supporting force, realizing smooth opening, buffered closing and free-position locking for various movable structures such as vehicle hoods, trunk lids, furniture cabinet doors, equipment hatches and industrial covers. With excellent durability and customizable performance, it is widely used in automotive, furniture, machinery, medical and other industries, greatly improving the convenience and safety of daily operation.

Key Features

1. Stable & Controllable Support: Filled with high-purity nitrogen, providing consistent, smooth and adjustable supporting force, realizing easy opening, soft closing and free-position holding without sudden impact.

2. Premium Sealing Performance: Adopts imported high-precision sealing rings and advanced sealing technology, effectively preventing gas leakage, ensuring long-term stable performance and long service life.

3. Robust & Durable Construction: High-strength steel cylinder with anti-corrosion coating, combined with precision-machined piston rod, resistant to wear, rust and fatigue, suitable for harsh industrial and outdoor environments.

4. Wide Customization Options: Fully customizable stroke, extended length, compressed length, force output, mounting fittings (ball joint, clevis, bracket, etc.) and surface treatment, to meet the specific needs of different applications.

5. Safe & Reliable: Built-in buffer structure to avoid impact damage to doors and equipment, with high safety factor, complying with international safety standards.

6. Easy Installation & Maintenance: Compact structure, various mounting fittings available, simple installation, no need for frequent maintenance, reducing operating costs.

7. Wide Application Compatibility: Suitable for various media and temperature environments, stable performance in high and low temperature conditions.

Installation & Maintenance Tips

• Select the appropriate gas strut model and force according to the weight, size and opening angle of the door/cover.

• Install strictly in accordance with the installation instructions, ensuring correct installation direction (the piston rod is downward when closed, to ensure lubrication of the sealing system).

• Do not disassemble, puncture or expose the gas strut to high temperature, to avoid safety hazards.

• Regularly check the mounting fittings and sealing parts for damage or looseness, and replace them in time if any abnormality is found.

• Avoid overloading the gas strut beyond its rated force, to prevent damage and safety accidents.
