The servo gearboxes of the new Neco® series feature high power density, extremely effective corrosion protection, and maximum flexibility in the motor connection – all in an elegant and compact design. Furthermore, we have developed a modular system that allows the customer to configure a custom gearbox quickly and easily.
High modularity for maximum flexibility
Ready to install and user-friendly
Blackbox concept minimises risks
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!
