SSV PG5

Bolt Tensioner with immersion nut (puller)

Cost-reducing - Powerful - Reusable
Bolt Tensioners can be removed from the bolt connection after pre-tensioning: in comparison, Hydraulic Nuts remain on the bolt or component connection.
The distinguishing feature of the Bolt Tensioners of product group 5 is that the pulling thread is part of the piston itself. The cylinder-piston-set is screwed immediately onto the recessed bolt thread.

Advantages

Bolt Tensioners

„Crossover-tightening“ of several bolts at several points is no longer necessary, since SCHAAF SSV and HM offer the possibility of tightening all the bolt connections simultaneously with exactly the same tensioning force. This also applies when increasing the tensioning force.
As opposed to thermal screw starting procedures, SCHAAF SSV and HM make it possible to eliminate different gaps between individual components. Each bolt can be tensioned with exactly the same force and not over the same distance!
SCHAAF SSV and HM make it possible to apply a residual tensioning force by means of test force stress application in order to determine if any settling of the screw may occur, and if so, to eliminate it.
With a compact unit and the ability to interchange the component parts relating to the size of the bolt, SCHAAF SSV can also be used for other thread sizes.
SSV and HM will dramatically save time required for tensioning applications. This effect increases for higher tensioning forces, larger bolt thread diameters and also the installation of several SCHAAF SSV or HM. Time savings up to 99% are possible! It is no longer necessary to apply large torque by hand. There is a number of handling features available, designed to make work easier with SCHAAF Bolt Tensioners and Hydraulic Nuts, especially when it comes to large dimensions.

Features SSV PG5

  • single-stage
  • thread in piston
  • for recessed bolt threads
  • smaller outer diameter of SSV compared with PG 4, otherwise like PG 4

Versions

In addition to a number of standardized Bolt Tensioners and Hydraulic Nuts, SCHAAF has already delivered thousands of customized axial Bolt Tensioners. The Design on Demand CAD system allows to realize customer solutions very quickly. Based on axial pre-tensioning technics, a number of patented, specialized solutions have been developed during the last years. Bolt Tensioners, Hydraulic Nuts and ExpaTen, as well as the A-Loc and EcoRolls, both developed especially for rolling mills, all represent a 100% system solution with SCHAAF’s accessories such as high-pressure hoses and high-pressure generators.

Areas of Application

The application areas for Bolt Tensioners and Hydraulic Nuts are unlimited. The great amount of user solutions have resulted in a great number of various designs. For this reason it is not always possible to classify all Bolt Tensioners and Hydraulic Nuts into a specific product group. For example, the tensioning force can be transmitted by a thread or a bayonet. Please contact us for your special application.
