What is a NitroSpring?

NitroSprings are the next generation in spring technology for industrial applications. High spring forces in an ultra compact package, providing a large range of spring travel and eliminating the need for preload, NitroSprings reset the perception of spring capabilities. NitroSprings are also compatible with digitisation, with the unique ability to individually or collectively monitor spring pressure, either on a constant or intermittent basis.

Advanced technology, flexibility and adaptability are key features which allows the NitroSpring to be used as a superior spring solution in a wide variety of industries

NitroSprings have a unique set of characteristics that can deliver significant advantages over tradition methods of generating spring force, including replacements for Bellville Washer or disc spring stacks, die springs, wire coil springs, urethane springs and even hydraulic cylinders.

NitroSprings can be used in a range of applications to provide forces for counterbalance, lift, tensioning, clamping, ejection, suspension, anti-vibration and safety overloads.

The Advantages of a NitroSpring

NitroSprings are the next generation in spring technology for industrial applications, providing a number of significant advantages over the traditional methods of generating spring force. NitroSprings are ideal replacements for Belville Washer or disc spring stacks, wire springs (both compressions and tension), die springs, urethane springs, hydraulic and pneumatic spring cylinders.

Major advantages

• Higher spring force – in more compact dimensions
• Ultra compact – space saving
• No preloads required - instant force on contact
• Long life – no fatigue and increased durability
• Force can be adjusted – providing the ultimate flexibility
• Consistent force over multiple sets of springs
• Force can be monitored – both constantly or at a set time, at the spring or remotely
• Long spring travel – up to 2000mm
• Can be overhauled – saving cost and time
• Sustainable option – up to 97% can be recycled or re-used through overhaul
• Multiple connection methods – making design and installation of the NitroSpring simple
• Spring progression rates – from 10% to 500%
• Ability to work in challenging environments – corrosion, debris, dirt, impact, submersion
