Gas Spring Features 

Low Maintenance 

Gas Springs require very little maintenance. Usually, a device with multiple parts would be more susceptible to wear and require regular maintenance checks. Still, gas springs avoid this issue by sealing their collection of components within an enclosed cylinder. They have an increased lifecycle over many other spring designs. For example, springs like tension springs rely on a mechanical method of operation.  

Long Lifespan 

Traditional springs, such as compression springs, consist of coiled metal, which will wear down over time and slowly reduce the amount of energy stored. Gas springs work with a gas-filled cylinder that supports their operation and prevents premature wear, making gas springs a device that can be relied upon to function effectively for its entire lifetime. 

Multi-Functional 

Some springs can be designed with an interior plunger that possesses a diaphragm sufficient to extend to the end of its housing tube. In this case, the gas spring will be immobile once consistent force is applied, which will result in the spring performing more like a traditional spring. The gas volume and internal pressure are reduced inside the tube by either a sliding mechanism or an end stop. This enables operators to adjust the properties of the spring to suit the application’s specific needs. 

Locking and Non-Locking  

An experienced spring manufacturer will offer locking and non-locking as a feature of their gas springs.  

• Non-locking gas springs are the most common, as the piston rod will automatically retract as pressure is exerted and return once removed. This provides an increased level of ergonomics compared to traditional springs, as the spring will give a smooth, consistent action when weight is applied. 

• Locking gas springs have a valve system that can provide force-dampening and keep the gas spring locked. 

FAQs

What Is a Gas Spring?

Gas springs generally consist of a cylindrical body filled with nitrogen gas, a piston rod and a seal, along with a guiding function for compression and extension. A pushing force created by the gas inside will extend the rod; the exact amount of pressure will be determined by the dimensions of the spring and the specific internal pressure. 

How Do Gas Springs Work?

The vital components used in Gas Springs rely on compressed gas to achieve their desired force, which can be compressed by a piston when a dynamic effect is needed. The key to this variability is the Schrader-type valve employed. This valve is a brass tube that is threaded along its exterior. A metal pin is found along the axis of the tube, and the valve body and a lip seal around the rod work with the valve. Compressed gas is injected through the tube using either a mechanical gasket (O-ring system) or high external pressures. 

Are Gas Springs Also Gas Struts?

Gas springs and struts seem very similar, but a few key differences are present due to the internal designs. Gas springs are designed for motion control applications, such as doors, windows and other equipment. In comparison to gas struts, gas springs create higher force with shorter strokes. Gas struts are mainly used in vehicle suspensions and contain a coil spring that supports the vehicle’s weight; these work in conjunction as a shock absorber that limits the effects of vibrations. 

What Are The Benefits of Gas Springs?

High-quality gas springs provide several benefits that have led to their increased popularity in many applications. These can provide: 

• A higher force in a smaller space 

• Built-in damping for improved control with movement 

• Energy storage, as gas springs don’t need power 

• They can work independently 

• Variable pressure to suit tasks 

• Can work in various environments, including contaminated or corrosive areas.
