Lift, Support, and Counterbalance with Excellence

Gas springs are pressurized cylinders containing both gas and liquid used for extension, support, and lift for any applications.

A compressed gas spring is an extended, self-contained force-generating device. The compression gas spring, also known as a compression gas strut, is a device used in a variety of industries to provide a compact, high-force solution to aid in lifting, balancing, and damping applications.

As your reliable compression gas spring manufacturer, we are proficient in supplying quality compression gas springs with uncompromising quality.

All You Need To Know About Compression Gas Spring

Compression Gas Spring and it's Benefits

Compression gas springs are mechanical devices that use compressed gas, typically nitrogen, to provide a pushing force. It works on the principle of Pascal’s Law.

For decades, we continuously implement lean production and automation to achieve the most competitive prices for your global clients. Our gas spring experts who have 20+ years experience are ready to give professional technical support and design services to you.

Structure of a Compression Gas Spring

Tube/Cylinder

The cylinder is the main body of the gas spring, usually made of steel or stainless steel.

Rod

The piston rod is a thin, elongated metal rod that extends out of the cylinder, usually made of steel(should be chrome-plated) or stainless steel.

Piston and Seal

The piston is connected to the piston rod and fits snugly inside the cylinder with a seal. The seal is a rubber O-ring that fits around the piston.

Gas

Usually nitrogen, which is non-reactive, non-flammable, and relatively inexpensive.

Guide sleeve

surrounds the piston rod and guides the piston rod move in a straight line. It helps to prevent the piston rod from bending or buckling under lateral loads.

End Fittings

The components that attach to both ends of the gas spring as connection parts.

Oil

There is typically a small amount of oil inside a gas spring to lubricate the seal and piston rod, reducing friction to ensure optimal performance.

How We Manufacture A Gas Spring?

1. Tube cutting and cleaning

We buy seamless steel tubes only from top manufacturers in China, same sources of suspa and stabilus. Then cut the tubes into appropriate lengths and fully cleaned.

2. End fittings and piston unit

The end fittings and piston unit are manufactured separately and then attached to the tube using welding or threading.

3. Filling with gas

The tube is then filled with pressurized 99.999% purity nitrogen to the required level. We buy nitrogen from AirProducts, which is an American brand.

4. Testing

The finished gas spring is tested for quality and performance, including pressure, force, and leak testing.

5. Surface treatment

Depending on the application, the gas spring tube must be treated with a coating or finish to improve its anti-corrosion level or appearance.

6. Packaging and shipping

Depending on the application, the gas spring tube must be treated with a coating or finish to improve its anti-corrosion level or appearance.

We Excel at Gas Springs, We're Happy to Help

We design precise gas springs tailor-made to your business and applications.

Gas Spring Connection Parts

Gas spring connection parts refer to the components used to connect gas springs to the application objective.

Explore more details about connection parts’ shape&sizes, material options, surface treatments: Gas spring end fittings and mounting brackets.

End Fittings

The components that attach to both ends of the gas spring are called end fittings. Common types of gas spring end fittings include Ball joints, Clevis, Eyelet, etc.

Mounting Brackets

Components that attach to the objective are called mounting brackets. Mounting brackets are not always a must depending on the mounting method.

Successful Cases of Compression Gas Spring Usage

We are excited to share some successful cases, which our compression gas springs are used in various applications for our clients globally.

Custom-tailor Your Gas Springs With MOQ of 100pcs

Placing a high value on bespoke design, we make sure that your compression gas springs are manufactured to your specifications.

Material: Top Grade Materials

We build our gas springs with chrome plated or stainless steel piston rods, with oil and pressurized nitrogen gas sealed in quality steel cylinders to ensure top quality.

Rod/Tube: 6/15, 8/18, 10/22, 12/25, 14/28

Designing gas springs requires precision for them to fit perfectly, our experts are happy to get accurate data for specific equipment.

Stroke Length: 30 – 1,000mm

Experienced specialists will work meticulously to take data for us to produce a gas spring with the precise stroke length that fits the specific machine.

Force: 50-1200N

The force is related to the weight of the object being supported. Providing us with accurate parameters, we will help you calculate the specific force.

Gas Spring Force Curve

This graph represents the force of the gas spring measured dynamically.

Because friction forces appear at the rod seal and on the piston, the gas spring will give more force when compression or less force when extension.

P1 is measured when the gas spring is static, F1 is measured when the gas spring is extending. Both forces are measured at 5mm from full extension.

How To Size A Gas Spring(Toolbox Lid Calculation)

To size a gas spring, you need to determine the following parameters:

Please feel free to consult with our expert to ensure your proper sizing and selection.

Compression Gas Spring VS Traction Gas Spring

The Compression gas springs provide pushing forces to push the piston rod outwards. They are typically used in applications requiring a pushing force, such as lifting hatches, doors, or lids.

The Traction gas springs, on the other hand, provide pull forces to pull the piston rod inwards. They are typically used in applications where a pulling force is required.

Frequently Asked Questions

1.Rod up or rod down when mounting a gas spring?

For the longer lifespan, it’s best to mount the spring as a “rod down” orientation. This keeps the seal and piston unit soak in the lubrication oil, so it has less chance of gas leakage due to dried out cracked seals.

2.How long do gas springs last? and warranty period.

Our gas spring is typically designed to last at least for 2-5 years. It is hard to say exactly how many years, because of different applications circumstances and working frequency. The lifecycle test in our lab(or SGS lab) pass 50,000 cycles or more.

Warranty period is 2 years, aside from misuse or physical damage or harsh working circumstances.

The main failure of a gas spring is the loss of pressure. While the sealing inside a gas spring is superior, it is completely normal for a very small amount of gas to continually leak out over time. But it won’t fail in overall performance.

3.Operating temperature of gas spring?

As standard our gas spring have an operating temperature range of -30°C to +100°C.
