Why Gas Springs are Fascinating


Have you ever seen a gas spring before? It’s a thin metal cylinder that supports doors and hatches. However, how does a small cylinder make heavy objects seem so light? Read more to learn what a gas spring really is.

What Is It?

A gas spring is made from a rod, piston and cylinder. The cylinder is full of pressurized nitrogen gas, which is used as a supportive and locking force. When you push the rod and piston into the cylinder, the gas is compressed. When you release it, the pressure of the gas forces it to move back to its original position.

This is because the amount of the nitrogen gas is the same within the cylinder, but the area changes. Because physical laws don’t change, this increases the pressure of the gas inside, which increases its force.

How Are Gas Springs Used?

We use gas springs as well as SPD gas springs shocks all the time. The force of two gas springs is the reason why your car trunk is so easy to open. Your office chair does the same thing. These all use gas springs to make our lives easier.

Are Gas Springs Safe To Use?

The cylinder is completely sealed, stopping any gas or oil from leaking. It functions so well that it will last for years. When the piston rod pushes the piston through the cylinder, it is greased by a lubricant oil that keeps the piston functioning smoothly.

Mechanical springs are different than gas springs. Compression springs are much more common and are made of coils. They are used in daily things such as pens and light switches.

Gas springs are relatively cheaper due to their compact design. They don’t use mechanical energy like compression springs, but you can find both everywhere. You can gas springs in some door hinges and car boot mechanisms.

Now that you know what gas springs are, keep an eye out for them. They are used in many ways, making heavy things become easy to lift.
