Flat head screw with tolerance compensation

Reduce stresses and extend service life

Stresses can put a heavy strain on machines and equipment in the long run. Use of flat head screws with tolerance compensation offers decisive advantages where fluctuating temperatures change the dimensions of a component, assembly inaccuracies occur, manufacturing tolerances must be compensated for or the position of the components vary due to dynamic loads.




To the products:

In many applications, components are moved along two parallel guides. For this purpose, guide rails are fixed to a bracket and the guide carriages are connected by a plate. The moving mass is mounted stably and backlash-free on both guides, so that the system is statically stressed. Where stresses occur, the forces must be absorbed by the guide, which increases the resistance to movement and reduces the service life of the components. To prevent static stresses in the system, it is often necessary to integrate a fixed and floating bearing arrangement. However, the innovative flat head screws with tolerance compensation from norelem offer an alternative solution.
Less effort during machining and assembly
The flat head screw with tolerance compensation is a screw for connecting two components while permitting a desired movement of the components in relation to each other (floating joint). The flat head screw consists of three components: Bolt, plain bearing and O-ring. The plain bearing compresses the O-ring by a pre-defined dimension when the bolt is screwed into the hole. The plain bearing will now be seated under the bolt head. The travel is accordingly limited by the installation dimension. This ensures a floating support with an almost play-free installation. The floating joint is limited to a defined dimension. Precise adherence to the tolerances of components in production and time-consuming alignment work are no longer necessary.

The Markgröningen-based company has various types of the flat head screws with tolerance compensation on offer. They are available with male or female thread, the structure of electro zinc-plated steel bolt, O-ring and plain bearing always remains the same.
