About us

In July 2007 Dr. TRETTER AG has taken over the production of Tolerance Rings in Neuhausen/Switzerland from the company Dr. TRETTER GmbH which had until then a factory for Tolerance Rings in Rechberghausen/Germany. Dr. TRETTER GmbH has been producing Tolerance Rings for more than 30 years. The production-trade company recognized the potential of this machine element. 

High standards of quality and innovative technology underscores the importance of Switzerland as a production site for machine elements. 

In April 2013 Dr. TRETTER AG relocated from Neuhausen to Beringen/Switzerland because existing production areas did not offer any further possibilities for expansion.

Tolerance Rings are available in many different designs.  In addition to standard sizes we also offer customer-specific solutions
