Torus revolutionizes the drive technology and the gear market.

Torus is the first technically matured planar-spiral-gear with highest possible gear transmission ratio and torque in one gear step.



The torus gear with the metal matching steel / bronze has been developed for highest requirements as far as load, efficiency, accuracy and running smoothness is concerned. It is offered according to customer specification in sizes between 0.1 and 10kW with a modular tooth design between 0.3 and 4 mm and a ratio of 1:20 to 1:400. Other solutions, deviating from the above datas are also possible. Please contact our sales team.






Torus-Plastic gears

The high demand for mini gears encouraged us to start the development of the torus gear in plastic material. This is why models in POM and PEEK are possible.





The patented torus technology will be exclusively designed and distributed by NIDEC GRAESSNER GMBH & Co. KG. In order to obtain the best possible benefit, all torus gears will be designed according to individual customer specifications.
