We produce tension bushes in accordance with DIN 1498 type for holes, and DIN 1499 type for trees, both with standard and special dimensions. The range of the elastic rings starts from a nominal diameter 10,0 up to 90 mm and over but under the constraint of the maximum thickness of 6.0 mm. Our technical office allows the customer to study special elastic rings that meet their needs


Our laboratory is able to detect and validate the dimensional characteristics, the hardness and the metallographic structures of the materials. Usually, the oiling phase provides the protective surface finish of our rings, but we can also offer different finishes such as: Geomet, mechanical and electrolytic galvanizing, phosphate, etc. …
Elastic rings are produced on demand only.
