Gas Spring Leading Manufacturer Welcomes You! Provides Self-locking, Adjustable, Damping Gas Springs! Committed to customized solutions, quality assurance, and prompt response and support. Widely applied in automotive, aerospace, medical, furniture, industrial automation, etc.

The gas spring utilizes the compression and expansion of nitrogen gas to provide pushing, pulling, or supporting force. Compared to traditional coil and disc springs, the gas spring offers smooth force output, strong adjustability, and easy installation.

A gas spring contains a piston, nitrogen, rod, and cylinder. The cylinder is filled with nitrogen gas, and the piston rod is separated from the gas by the piston. One end of the piston rod protrudes and is connected to the object that needs support or propulsion. When the piston rod is pushed into the cylinder, the nitrogen gas inside the cylinder is compressed, generating outward thrust. When external force is removed, the compressed nitrogen gas pushes the piston rod back to its original position.

The gas spring is widely used in supporting tailgates and hoods in cars. Adjusting the height of office chairs, damping, and shock absorption in mechanical equipment. And assisting in the opening and closing of furniture doors. Depending on specific requirements, we design the gas spring as free type, self-locking, damping, or adjustable.


Categories of gas spring

Freestyle gas spring:

This type of gas spring is primarily used for support and can stop freely at any position. It compresses air or nitrogen as the spring medium inside. The support force can be adjusted by changing the internal air pressure. Widely used in applications such as supporting car trunk lids and mechanical equipment covers.
