MJP Special Solutions

Multi-Jackbolt Pretensioners (MJP) made to measure

Where no solution can be found with our PM standard series or the PB basic series, we will be happy to develop an application-specific special solution for you, taking into account all the necessary parameters, in particular:

Larger diameters (> M160); for very large diameters also multi-part nut bodies
Special thread geometries (profile, pitch)
Special materials (corrosion-resistant, amagnetic, coated (e.g. protection against cold welding))
Extended temperature ranges (extreme low/high temperatures)
Special designs (e.g. particularly space-saving designs)
Other application-specific designs

and much more.

Bolting solutions for highest loads

We calculate, develop, design and produce the best technical and economical bolting solutions for large dimensions and high, precisely adjustable and re-releasable pretensioning forces in accordance with the specific requirements of our customers and on the basis of our high-quality mechanical PM Multi-Jackbolt Pretensioners (MJP).

PM Multi-Jackbolt Pretensioners (MJP)

Mechanical Multi-Jackbolt Pretensioners (MJP) are the perfect solution for purely axial pretensioning.

MJP are designed according to ISO 898-2 and are used for highly loaded bolting applications in all areas of industry.

Due to the captive mounted Mammoth™ Jackbolts they are best suited for highly dynamic applications.

PB Radial Pretensioning Bolts (RPB)

The unbeatable combination of all advantages for combined axial and radial pre-tensioning of highly dynamic components such as flange couplings, turbine runners or dynamically loaded foundations:

in conjunction with
Conical Bolt and Conical Split Sleeve

Special solutions

Larger diameters (> M160), special thread geometries, special materials, extended temperature ranges or other application-specific designs.
