What are gas springs?

Gas springs are a type of spring mechanism that uses compressed gas, usually nitrogen, to exert force. They consist of a cylinder and a piston rod and are used to control the movement of a load by damping and braking the movement.

How do they work?

When the piston rod is pushed into the cylinder, the gas is compressed, creating a back pressure. This back pressure is what provides the force to either lift or hold a load. When the piston rod is pulled out, the gas expands and allows movement.


Gas springs are used in a variety of applications, including: • Vehicle tailgates and engine hoods • Office chairs • Machinery and industrial equipment • Furniture and home decor
