NITROSPRINGS VS HYDRAULICS
What is a Hydraulic Cylinder?
Hydraulics are often used in applications to act like high powered springs. The hydraulic cylinder is connected via pipes and fittings to an accumulator. The accumulator has the stored energy that provides a spring like action to the cylinder.
Gas springs, in many of these applications can replace the whole hydraulic system of cylinders, pipes and accumulators, combining these elements in one single compact package. The NitroSpring version is a simple plug and play type, requiring no pipes or connections. It is therefore resistant to leaks and does not require complex installation and bleeding.
Introducing Hydro-NitroSprings
Hydro-NitroSprings are the latest evolution of our heavy duty industrial gas spring range. This latest innovative product range from Metrol, combines our industrial gas springs with hydraulics to produce precision controlled movement.
Gas springs contain stored energy, whilst hydraulics provide controlled movement through the flow of oil. Combining these two technologies provides a range of cylinders that can perform like springs, but can be moved like hydraulics.
Type C: Hydro-Nitro Compression
Gas pressure provides a compressive force, and acts like a normal gas spring. The hydraulic port is located in the upper section of the cylinder, with the hydraulic force compressing the piston rod in.
Ideal for applications where a gas spring is required to provide a compressive force, but the piston needs to be retracted for movement.
Type T: Hydro-Nitro Traction
Gas pressure provides a traction force, pushing the piston rod in. The hydraulic port is located on the lower section of the cylinder, with the hydraulic force pushing the piston rod out.
Ideal for applications where an extension type of force is required to be applied, but the piston rod needs to be pushed back out for movement.
Hydro-Nitro damping – removing shock loads from hydraulics
Traditional hydraulic cylinders can often problems where the movement reaches a dead stop. This sudden stop can cause damage to framework or other components within an application.
Hydro-NitroSprings can provide an element of cushioning to single acting hydraulic cylinders, were damped movement prevents shock loading, vibration and excessive noise. The Hydro-Nitro, available as a Type C or Type T variant come as a single cylinder only requiring the hydraulic input.
Upgrading to a NitroSpring
Replacing your Jarret cylinder
We’ve made replacing your Jarret cylinder with a NitroSpring as easy as possible. Simply fill out our NitroSpring enquiry form or provide us with a drawing of your current Jarret cylinder. With this information, we will begin working on a proposal including a drawing, quotation, and lead time.
Frequently Asked Questions
Is there an alternative to Jarret cylinders?
Yes, our NitroSprings have been designed to replace a variety of spring solutions, including Jarret cylinders.
How do I replace a Jarret cylinder with a NitroSpring?
For our team to begin designing a NitroSpring replacement, simply complete the enquiry form with the required information, or send us a drawing of your current Jarret cylinder.
Can you replicate the same force as a Jarret cylinder in a NitroSpring?
Yes, not only are our NitroSprings designed to have the same force and force curves as a Jarret cylinder, but they are flexible due to their degassing and recharging abilities.
Will I need to modify my equipment to change from Jarret cylinders to NitroSprings?
No, NitroSprings specifically meet the exact needs of your application, meaning no modification is required and installation is straight forward.
The Jarret cylinders work in a hydraulic fluid or hydraulic cylinder, is a NitroSpring alternative suitable for this?
Yes, NitroSprings can have added features, such as a special set of advanced seals, allowing them to work reliably in pressurised hydraulic fluid.
Jarret cylinders are used in Steel Mills, as an alternative, can NitroSpring gas springs be used in steel mills?
Our NitroSprings have been manufactured to withstand working in both hot and cold rolling mills. Our unique designs deliver long-lasting performance like no other.
What is the delivery time for a NitroSpring Jarret cylinder replacement?
Generally, our NitroSpring manufacturing lead time is between 8 to 12 weeks. However, we also cover blanket orders and call offs to minimise lead times and capital outlay.
Can I rebuild a NitroSpring steel mill cylinder?
NitroSpring steel mill cylinders can be overhauled in your facility or at our Northampton facility. We can send out trained professionals to carry out this service; alternatively, we also offer certified training for your staff. Metrol’s unique and advanced design allows the spring to undergo a simple rebuild, with minimum time and effort needed, guaranteeing a full life product after the service.
