PACKED WITH ADVANCED FEATURES
PROVIDING UNRIVALLED PERFORMANCE

we’ve designed the range with this in mind. Therefore, you can adjust the force of NitroSpring products yourself, in a controlled manner with high accuracy. This can be done in the field, without having to remove it from the application, the ultimate versatile option.

This specialist solution is a fully customisable product, making it a universal fit for almost every application. NitroSprings are built to your specific requirements every time, ensuring your needs are met.

For example, if you are replacing a wire spring and are conscious of space, a NitroSpring can achieve a much greater force in a more compact package. They also do not require a preload as they are already charged.

Right: PAV (Precision Adjustment Valve) side port allows accurate adjustment of pressure.

Rod wipers that prevent ingress of contaminants that can reduce gas spring life.
Tertiary wiper system comprises dual role redundancies. (See parts highlighted).

NASS (NitroSpring Advanced Sealing
Systems) combination of specialist seal solutions offers unrivalled performance and durability compared to other gas spring products. Advanced two stage
sealing system. (See parts highlighted).

Enhanced dual guidance system, reducing the effects of lateral loads
and improving longevity for seals. Tandem rod guidance
components. (See
parts highlighted).

Rod Diameter – This refers to the exterior dimension of the rod.

Body Diameter – This is the exterior dimension of the body; it is important that this fits into your application. 

Stroke Lengths – The length of the usable stroke. 

Threads – Threads are at either end of the gas spring and they attach onto end fittings. The end fitting can be part of the product itself if you do not want a thread. Different threads will be suitable for different end fittings. 

Force Range – In variable NitroSprings, you can adjust the pressure to your desired force. Therefore, if you ordered a spring with a force range of 300N – 5000N, it would arrive charged to 5000N and you could reduce it anywhere down to 300N.

Force Progression – This refers to a NitroSpring becoming harder to compress the more you push it down. The higher the force progression, the harder it will be to fully compress it. 

Extension Speed – This is how quickly the NitroSpring returns to its full extended length after being compressed. 

Working Temperature Range – NitroSprings can perform in temperatures between -30 - 80°C. 

Rod Material & Body Finish – This is important to consider to ensure your NitroSpring has the correct material and finish to perform under the conditions it will be exposed to. 

Guarantee – Metrol offer a 2-year guarantee against manufacturing defects.

The various features available to this range offers the perfect solution; from advanced sealing systems that provide ultimate durability, to the versatility of being able to accurately adjust gas spring force in situ. Not to mention, our full service, including design, application consultancy, and prototyping means we provide more than just a product.

Due to NitroSprings being a bespoke product, they can be suited to almost any environment and application. For example, the agricultural industry benefits from using NitroSprings to auto-reset the arm or break leg in a cultivator. Other industries include Automotive, Food Processing, Medical, Manufacturing, Automation, Plant and Machinery, and Marine. 

How do I choose the right stroke length for my NitroSpring?

The right stroke length is the length of the distance you need your application to move. 

Is the force of long stroke NitroSprings adjustable?

Yes, they are variable force NitroSprings and can be adjusted in the field using the precision adjustment valve. The pressure can be increased using charging equipment that is available on request. 

What environments are these gas struts suitable for?

They are suitable for heavy-duty environments where a bespoke product is required. 

Can I install these gas struts myself, or do I need a specialist?

Yes, you can install NitroSprings yourself.

What is the lead time for orders?

Lead time for low and high volume NitroSpring orders vary, depending on the level of customisation. You will be provided a time frame for your order at the beginning of the project.
