Materials and qualities

The inner values count - a good way to describe the world of materials. Although some of our bearing materials may look the same, each material has its own special purpose. To ensure that your component functions in practice, we manufacture from all common steels, non-ferrous and light metals.


Our stock is mainly characterized by:

  • Tempered steels according to ISO 683
  • Steels for high and low temperature applications according to EN 10269 
  • Stainless and acid-resistant steels according to EN 10088 

We can procure almost any other material within a very short time thanks to our well-connected network of suppliers. Every material is stored by us absolutely batch-clean and is traceable.
If your desired material does not appear on our list, please do not hesitate to contact us.
