150 years full of stories, innovations, and passion.


A pioneer of the industrial age founds RENK.

Our founder started RENK in a garage in Augsburg. Thanks to his passion and innovations the garage was not sufficient anymore and the first factory was needed.


Quantum leap

RENK constructs a gear cutting machine with a processing diameter of seven meters.



The first reversing gear units for marine applications are built.



RENK builds the fastest gear box in the world.


Global innovation

RENK produces the first turbine gear box with the highest pitch circle velocity (185 m/s).



RENK manufactures one of the largest marine gear boxes for ice going ships with a diesel motor drive. Power: 40,000 kW.



The company's name is changed to RENK Aktiengesellschaft – including the product areas of automatic vehicle transmission, drive elements, and test systems.
