What is Gas Spring?

Gas springs (gas struts or gas shocks) are mechanical devices that use compressed gas to generate a force and facilitate motion. They are commonly used in applications requiring smooth and controlled support, lifting, damping, or lowering action, such as in office chairs, automotive hoods, and hospital beds.

Gas springs have several advantages over other types of mechanical springs, including:

Smooth operation

Gas springs can provide a smooth and controlled motion

Low Maintenance

requiring no lubrication or adjustment

Space-saving

Compact and designed to fit into small spaces, Ideal for limited space applications

Long service life

JP gas springs are designed to withstand high loads and harsh environments with a service life of up to 100,000 cycles

How Does Gas Spring Work?

Gas springs are piston-cylinder devices that use pressurized nitrogen to produce a force. But how is the force generated, and how big is it?

 

As you can see from the sectional view of a gas spring below, Area A is always a bit smaller than Area B, which is caused by the rod area. The surface area difference on both sides of the piston generates the force. So, theoretically the force of a gas spring can be calculated by this simple formula:

 

F=P*(B-A)

P means the gas pressure inside.

B minus A means the area difference.

 

When gas spring compresses or extends, gas can move through a hole(or a valve) from one side to another, maintaining pressure on both sides. Also, the net compression or extension force will near-constant.

 

Gas springs are generally considered to have near-constant force throughout the stroke, with a K-factor indicating the slight increase.

How to Measure and Install Gas Springs

How to Measure a Gas Spring

To measure a gas spring, you need to take several key measurements, including the extended length, compressed length, and rod and tube diameter.

Consult our technical expert if you need help properly measuring and selecting a gas spring for your application.

How to mount and unmount a gas spring

It’s important to follow proper safety procedures when handling gas springs, as they contain high-pressure gas and can cause injury if mishandled.

Key Factors to Consider When Choosing a Gas Spring

Force

This is related to the weight of the item to lift, lower, or support. High forces require bigger sizes of gas springs.

Stroke

The distance the gas spring will need to travel in your application.

Environment

The operating temperature and corrosion resistance you want to have. etc.

Mounting and end fitting

How gas spring fixs into your application.

Quality and durability

Choose a reputable manufacturer that produces high-quality, durable gas springs that will withstand the rigors of the application.

Different Types of Gas Springs

There are some types of gas springs, differenciate by design and funtions, they are:

Gas Springs Applications

Regarding the purpose and function, gas springs can be roughly divided into two types: compression gas springs and locking gas springs. Let’s take a look at different gas springs and their applications to see which type of gas spring is suitable for your product.

Compression Gas Springs

Compression Gas Springs

Compression gas springs are used in a variety of applications where objects need to be lifted, lowered, or supported effortlessly without using great force. They are widely utilized to open and hold items of furniture, automotive applications, medical, sports, and more.

Applications

Locking Gas Springs

Locking Gas Springs

Locking gas struts make it possible to lock in any stroke position along their range, whether elastically or rigidly. Our locking gas springs offer high performance when it comes to smoothness, and they conveniently lock objects in any location.

They are seen in various applications such as hospital beds, hospital furniture, passenger seats, emergency trolleys, and more.

Gas Spring VS Coil Spring

Gas Springs and Coil Springs are both mechanical devices used for providing force, but they are quite different. Gas springs some obvious advantages against coil springs. Refer to the chart below:

Criteria

Gas Springs

Coil Springs

Controlled Motion

Can provide smooth and precise controlled motion

Hard to achive

Constant Force

Near constant force, small K-factor

Big differences throughout the travel

Installation

Easier to install and remove

Requires more effort for installation and removal

Damping

Offers controlled damping

Offers limited or no damping

Adjustment

Adjustable damping and locking features

Non-adjustable

Size

Smaller size and compact design

Bulkier and larger in size

Safety

Safer due to controlled movement and locking features

Less safe due to uncontrolled movement
