Gas spring support rod is an industrial accessory that can support, cushion, brake, adjust height and angle. Including pressure cylinder, piston rod, piston, sealing guide sleeve, packing (inert gas or oil gas mixture), in cylinder control elements and out of cylinder control elements (see controllable gas spring), connectors, etc. The principle of gas spring support rod is to fill a sealed pressure cylinder with inert gas or gas mixture, so that the pressure of the chamber can be increased to several times or tens of times the air pressure. The movement of the piston rod can be achieved by the pressure difference generated by the cross-sectional area of the piston rod being smaller than that of the piston. They have fundamental differences in principle, so gas springs have significant advantages over ordinary springs. That is to say, the speed is relatively slow, the power change is not significant (usually within 1:1.2), and it is easy to control.

The disadvantage of gas spring support rods is that they have a relatively smaller volume than spiral springs, higher cost, and shorter service life. Unlike mechanical springs, gas springs have almost linear elastic curves. The elasticity coefficient x of a standard air spring is between 1.2 and 1.4. Other parameters can be flexibly defined according to requirements and operating conditions.
A gas spring support rod is a component that can provide support, cushioning, braking, height and angle adjustment, and other functions. Mainly used for lids, doors, etc. in construction machinery.
