The area of "General Machinery" includes applications for original equipment manufacturers.

Typical applications are bolted connections on

Pumps
Gears
Slewing rings
Couplings
Anchorages
Cylinders

and many more.

In close cooperation with the engineers, our products are optimally developed for each application. In addition, we offer support in the design and dimensioning of the entire bolting system.

As far as technically possible, we supply standard MJP of the PM08, PM10 and PM12 type series. Where necessary, special solutions in suitable materials are individually designed and manufactured for each application.

Radial pretensioning bolts (RPB) are the ideal solution on large couplings for the safe transmission of high torques.

All products are made of high-quality materials. Audits, tests, verifications and certificates of all kinds are possible.

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:

PM Multi-Jackbolt Pretensioners (MJP)
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.
