High-performance Synchronizer Rings from Diehl Metall for Transmission Solutions

Diehl Metall Schmiedetechnik

On our Internet site, you will find the latest information on our synchronizer rings made of brass and steel as well as on innovative friction layers.

Diehl Metall Schmiedetechnik is a company rooted in tradition, producing both conventional forged brass synchronizer rings as well as steel synchronizer rings with high-performance coatings. These synchronizer rings fulfill the highest requirements with respect to exact geometry, high wear resistance and strength. 

Uncoated brass synchronizer rings with friction thread are the standard solution for all passenger car transmissions. Combined with innovative friction layers, brass synchronizer rings may even be used in highly loaded transmissions. Moreover, Diehl Metall produces steel synchronizer rings which are excellently suited to high-performance transmissions. In contrast to forged brass synchronizer rings, these are produced by means of sheet-metal forming. Depending on customer requirements, the steel synchronizer rings undergo different heat treatment processes and may also be provided with ground friction surfaces upon request.  

With a comprehensive selection of friction coatings, Diehl Metall is able to provide efficient synchronizer rings for all application areas. Its innovative product portfolio sets innovative trends for transmission solutions.
