Sumer Gearbox from Sumer Transmissions
Founded in 1979, SUMER designs, assembles and markets gearing transmission systems
Sumer manufactures speed reducers with low backlash and without backlash for leading high-tech industries : space, nuclear, armaments, aeronautics, vacuum, robotics, servomechanism and specific mechanisms.
In 1993, Sumer was decentralized and relocated in the Roqual Industrial estate in Sarlat, Dordogne where it continues to develop its activities. To-day Sumer is ready to extend its business to the European and World markets.
Our very high precision gearboxes are designed for high tech industries such as :
Robotic, aeronautic, armament, nuclear, aero spatial, petrochemical, vacuum, and for any other special machine automatisms.
There are two main groups:
- High precision gearboxes (planetary, bevel and worm wheel) are intended for applications which require utmost torsional stiffness and high radial/axial loads.
- Gearboxes with higher backlash: for classic applications where angular precision which is less than 12 arcmin is less important. planetary and bevel gearboxes.
