Gas spring is a kind of elastic supported part with damping force, using the compressibility of the charged gas to produce elasticity. When it is working, the damping force from the charged gas and filled oil going through the hole in the piston, control the speed of the gas spring. Now, we can offer Compressible Gas Springs, Balanced Gas Springs, Lockable Gas Springs, and many new specific function gas springs like Pressure Adjustable Gas springs, Double-damped Gas springs, Double rod Gas Springs, Pulling gas springs, Safety Locking Shroud Gas Springs, Stainless steel gas springs, Three-section Gas springs, etc. We can also make new developments according to customers’ samples, drawings, or even their ideas for designing new kinds of gas springs.
