Double-tube Telescopic Shock Absorber

Hydraulic Cylinder Damper is a high-performance damping device that uses hydraulic fluid as the working medium and regulates the flow of fluid through a precision valve system to achieve efficient vibration absorption and energy dissipation. The compact design and easy installation of the cartridge structure can effectively improve driving smoothness, handling stability and ride comfort.

simple structure:
Integral sealing design, excellent dustproof and oil leakage prevention performance;
Double-cylinder structure (inner working cylinder + outer oil storage cylinder) realizes more stable oil circulation;
Compact design saves installation space.

Highly efficient vibration damping performance: 
High-pressure nitrogen design prevents oil cavitation.By filling the shock absorber with high-pressure nitrogen, it effectively suppresses oil cavitation—a phenomenon where air bubbles form in the hydraulic oil under low pressure, which can cause irregular damping and reduce performance. The nitrogen pressure maintains a stable environment within the cylinder, ensuring the hydraulic oil remains in a homogeneous state. This allows the damping force to be transmitted smoothly, even during rapid compression and rebound cycles, providing consistent control over the vehicle's movement.
Linear damping characteristics provide a more natural ride;
Low heat attenuation design maintains stable performance over long periods of time.

Quality Assurance: 
High-strength steel barrel, surface rust treatment (spraying), rigorous bench testing (fatigue test, salt spray test, etc.) to ensure that more than 100,000 cycles without failure, corrosion resistance.
Precision piston rod by high-frequency quenching and chrome-plating process, wear-resistant and scratch-resistant, excellent sealing.
The sealing system adopts high-quality oil seals and guide components, anti-oil leakage design, long service life.
The model supports nitrogen gas pressurization to further reduce the phenomenon of vacuoles.

Wide adaptability: 
Support customized damping parameters, we are a professional factory can adjust the damping parameters according to customer needs.Whether you want a stiffer or softer damper, the choice is yours.
Wide operating temperature range (-10℃ to +120℃), suitable for harsh environments.
