Working Principle

A compression gas spring consists of a cylinder, piston rod, sealing and guide package, and mounting joints.
In operation, the sealed pressure cylinder is filled with inert gas or an oil-gas mixture, maintaining the chamber in a high-pressure state. The pressure difference between the two sides of the piston, caused by their different cross-sectional areas, drives the piston rod to extend freely, providing smooth support or damping motion.

Materials and Surface Treatments
  • Piston rod: Alloy steel / stainless steel / aluminum alloy, with optional surface treatments such as chrome plating or nitriding (QPQ) for enhanced wear and corrosion resistance.
  • Cylinder and end fitting: Stainless steel / alloy steel / aluminum alloy, available with electroplating, water-based, or oil-based coatings to suit different operating environments.
  • Piston: Powder metallurgy / aluminum alloy / alloy steel, ensuring reliable sealing and long service life.

  • Stable control: Slower motion and smaller dynamic force variation (elasticity coefficient X typically between 1.2–1.4) make them easier to regulate.
  • Smooth operation: The near-linear elasticity curve provides a more comfortable, steady, and controlled movement during opening and closing.
