Expertise and service

SKF has worked in the field of bolt-tightening by pre-load tension since the 1940’s. At that time, design studies concentrated on the tightening of slewing rings. Since the 1940’s, SKF has continuously furthered its bolt-tightening experience in every industrial sector and in many different types of applications.
Well aware that good tightening control is extremely important economically, SKF offers both expertise and service to solve any problems involving the tightening of bolted assemblies.

Why is it so important ?

The design and implementation of a bolted assembly requires a very strict methodological approach, for errors can lead to costly and often disastrous failures. In bolt-tightening, it is fundamental to control the level of the tightening load, as well as the accuracy of the tightening value to ensure that required performance of the bolted assembly will be achieved.

Benefits

In comparison to traditional tightening methods, tightening with Hydrocam bolt tensioners offers many advantages :

• no torsion stress
• good accuracy
• easy implementation
• no damage to components
• process automation possible
