Closed plug-and-play solutions
Our gearbox units combine cutting-edge technology and maximum user-friendliness in a compact design. The backlash-free plug-and-play solutions are fully enclosed and have components such as output and drive bearings as well as a sealing system already on board. Users benefit from outstanding performance, simple integration and absolute reliability with a long service life.
Performance meets user-friendliness
The gearbox units are based on the gearbox sets and, in addition to a tilt-resistant output bearing like the gear sets plus, also have a tilt-resistant input bearing and a sealing system. The fully enclosed strain wave gears are ready for immediate installation and very easy to handle thanks to the plug-and-play concept. The outstanding performance enables significant increases in performance and efficiency in your automation. Depending on the application, you can choose between a hollow shaft variant for the passage of external media or a solid shaft with minimal mass inertia.
