Misumi Lift Struts Manufacturer

Short Description:

Gas spring is a mechanical component that achieves elastic function by sealing high-pressure gas (usually nitrogen), and its working principle is based on the physical properties of gas compressibility. When subjected to external forces, the internal piston compresses the gas and stores energy; When the external force disappears, the gas expands and releases energy, providing stable support or buffering effect. Compared to traditional mechanical springs, gas springs have advantages such as adjustable force, smooth motion, controllable damping, and can provide approximately constant elastic output. They are widely used in fields such as automobiles, furniture, and industrial equipment to achieve height adjustment, gradual lowering and closing, and improve the dynamic performance of mechanical systems.
