The easiest-to-use bolt tensioner in the world
New from Nord-Lock is the Superbolt NXT multi-jackbolt tensioner which the company says is up to 30% faster to install than existing solutions.
Safely reducing the installation and maintenance time of tightening large bolts has long been at the core of Superbolt technologies. With Superbolt NXT, Nord-Lock says it is taking those capabilities to the next level.
Everything has been designed with user simplicity, safety and speed at the forefront. A typical M76 multi-jackbolt tensioner can have up to twelve individual jackbolts, whereas the M76 Superbolt NXT achieves the same secure preload with just eight. This, plus a new knurling grip layer to support with handling during installation and removal, and a host of other user-friendly features elevates Superbolt NXT to the easiest-to-use bolt tensioner in the world.
“It started with a strategic initiative to improve the customer experience when using a Superbolt multi-jackbolt tensioner,” says Sébastien Bruyas, strategic sales manager for Nord-Lock Group.
The key improvement has been reducing the number of jackbolts required to tighten the bolt, as a small decrease in jackbolts can deliver a large decrease in the tightening time. To achieve this, design engineers had to rethink this critical component.
“We worked with some of the best steel mills and heat treatment partners in the world to get the right materials and processes to increase the strength of our jackbolts. Now, we can offer the customer an equivalent preload with fewer jackbolts, so it’s faster and easier to install with less torque,” says Max Bastiaansen, R&D project manager for Nord-Lock Group.
Bruyas adds: “Take two products side-by-side, and you will see a visible difference between Superbolt NXT and a competitive multi-jackbolt tensioner – it might have two, four or six fewer jackbolts.”
Superbolt NXT also features a black oxidised coating for corrosion protection, laser-markings to guide installation and an anti-slip knurling grip layer. It is instantly recognisable in comparison to the grey tensioners available on the market until today.
