Versatility in tightening large nuts

31st March 2017

Mechanical tensioning and hydraulic tensioning are common methods to tighten large size bolts, each with its own strong advantages. Superbolt multi-jackbolt tensioners have been on the market since 1984, allowing bolted joints to be tightened mechanically without specialised skills or heavy tooling. But what if there was a product that combines the strengths of both Superbolt mechanical tensioning and hydraulic tensioning into one?

The new VersaTite™ Hydraulic Mechanical Tensioner fromNord-Lock Group combines the speed and uniformity of hydraulic tensioners with the accuracy of Superbolt mechanical tensioners.

Superbolt VersaTite gives versatility in multiple ways, including:

  • VersaTite products can be hydraulically pressurised to achieve a fast and uniform initial preload. The solution incorporates Boltight hydraulic tensioning with state of   the art seal and pressure
  • The achieved preload of VersaTite products is easily controlled by mechanically applying the final torque utilising Superbolt multi-jackbolt
  • Removal is just as versatile - either mechanical or hydraulic removal is possible. The operator chooses depending on location, amount of fasteners, space constraints as well as time and tooling

“Superbolt VersaTite is a result of our efforts to understand and solve the challenges our customers face,” comments Steve Busalacchi, tensioning specialist from the Nord-Lock Group. “Versatility in assembly and removal; safe and efficient operations; and increased application uptime; are some advantages the new solution brings. The new product truly offers versatility in one nut – that is why we named it VersaTite. No drawbacks - just added benefits.”
