NITROSPRINGS VS COMPRESSION WIRE SPRINGS
What is a compression wire spring?
A compression wire spring is made from coiled wire in a helical shape. It aims to resists compression when a force is applied to it by exerting a push movement against the pressure. These characteristics make them ideal for absorbing shocks and controlling motion.
Replacing a compression wire spring with a NitroSpring will provide you with unrivalled advantages such as longer lifespan, reduced fatigue, pressure monitoring, enhanced durability, damping, and many more!
Advantages of NitroSprings over compression wire springs
No preload and variable forces
Since our NitroSprings are charged to your desired force, there is no need for preload, meaning you do not lose some of the travel to load it. This results in a NitroSprings ability to be smaller overall and easily recharged and degassed to the necessary forces.
High forces in a compact package
The NitroSprings’ condensed design makes them suitable to fit in small spaces, whilst still being able to generate high forces. A compression wire spring would need to have thick diameters, and long wire lengths to achieve a force of 500N. Whereas, a NitroSpring can have a force of 500N whilst having relatively small diameters and lengths.
90% of stroke in travel length
NitroSprings can achieve a much greater travel than wire springs since they can be compressed to 90% of their stroke length. A wire spring’s travel is limited by factors such as the thickness of the material and how tightly coiled it is. This determines how much it can be compressed and the force required to do so.
A NitroSpring stores force when it is in its resting state meaning that it is always preset. This means that there is no reduction in its free length and it retains its full travel capability.
Damping
The oil within a NitroSpring chamber allows for a controlled damping movement. This is ideal for soft closing applications to prevent damage and general wear. The oil has a higher viscosity than gas, meaning it passes through the orifices slower, creating a damping motion to the desired force.
Cost-effective
Our NitroSprings are guaranteed to deliver a minimum of 1 million cycles when used according to the recommendations. NitroSprings can also undergo an overhauling process to restore them back to brand new, instead of needing to replace them. This makes them a more cost-effective solution as they last for much longer without the need to be replaced.

Frequently Asked Questions
What market sectors can NitroSprings be used in as an alternative to compression wire springs?
- Train stillages – the NitroSpring withstands heavy loads and doesn’t suffer from fatigue like a wire spring does, therefore keeping the suspension effective and reliable.
- Industrial machinery – NitroSprings successfully deliver consistent forces that can be monitored regularly, promoting safety and reducing the risk of sudden failures.
- Automotive – by absorbing shocks due to the single cylinder build, NitroSprings help to reduce daily damage to automotive components, such as suspension systems. This absorbed energy also promotes comfort to the driver.
- Marine and offshore – A NitroSprings performance is not affected when submerged under water. Corrosion resistant options are available and will provide a longer lifespan in comparison to wire springs.
- Packaging and Automation – The ability to repeatedly work under high speeds and forces make NitroSprings more suited to demanding packaging and automation industries. A wire spring would not be able to achieve this standard of repetitive and tiring use for as long as a NitroSpring can.
What applications can use a NitroSpring instead of a compression wire spring?

Is a NitroSpring as reliable as a wire spring?
When designing the NitroSpring, reliability was one of our upmost priorities, because of this they are manufactured with several advanced features. To start, the pressure can be constantly or regularly monitored through either connecting a valve to a pressure tester, or a dial which sits in the body of the NitroSpring. This allows you to see if the pressure has dropped and therefore prevents sudden failure. If a wire spring was losing its force, it would become deformed overtime, and this wouldn't necessarily be obvious to the human eye. This means it could unexpectedly fail and potentially break your application/cause injuries.
When purchasing a wire spring, it has a set force. A NitroSpring can be recharged, degassed, and have the force adjusted to allow for flexibility, therefore promoting reliability.
A NitroSpring can complete a minimum of 1 million cycles whilst under extremely heavy loads such as 20 tonnes! It can perform for long periods of time with minimum downtime needed. On the other hand, a wire spring is much more likely to suffer from material fatigue under these conditions.
