Innovative gear concept

With the Neco® series we have created a modern and economical gear solution that fulfils the most stringent requirements for performance and user friendliness. The modular design features comprehensive corrosion protection with a low-inertia clamping ring for an enormous boost in performance and a broad application spectrum. Assembly of the motor is likewise reduced greatly since no alignment of the drive pinion is necessary. Neco® gears can be adapted for use with all standard servomotors, ensuring fast installation and assembly. The intuitive way to find the right gearbox: The introduction of Neco® is accompanied by a newly developed gear concept that makes it very easy to find, configure, install and use the gears. Ordering and handling of our gears has never been so easy!
