Nabtesco gearboxes for robotics: resilient, precise, powerful
Gearboxes are a core technology in the design of robots. As converters of torque and speed, they are a central component in the drive train and have a decisive influence on the performance data of the kinematics - particularly in terms of accuracy, reproducibility and service life. The following applies: Every robot is only as good as its gears.
We are an established system provider, experienced solution specialist and close development and design partner for robotics, working with all recognized robot manufacturers and reliably supporting the growth of our customers. Our innovative precision gearboxes offer high performance in the tightest of spaces and ensure maximum productivity and robot availability. With our many years of experience and in-house engineering, we help you to solve your problems together. We love a challenge and will find a solution for every requirement.
Precise in any size: robot gearboxes for every requirement
Our robot gearboxes are absolutely precise, extremely dynamic, exceptionally durable and extremely compact and continue to work smoothly and reliably even after millions of cycles. Our range includes both cycloidal gears and strain wave gears and is characterized by complete scalability from 7 to 70,000 Nm. This is unique on the market.
The advantages at a glance:
- Extreme precision (strain wave gears: absolute zero backlash, cycloidal gearbox: hysteresis loss < 0.5 arcmin)
- High torsional and flexural rigidity - even at high speeds and high loads
- High reduction ratios in one stage
- High shock load capacity (500 % of the rated torque)
- Very compact design and therefore easy to integrate even where space is limited
- Optional hollow shaft - ideal for feeding cables and hoses through
- Gearbox is a load-bearing machine element thanks to integrated main bearing
- Very low wear with a long service life
- Product design compatible with series production
- High degree of modularity and standardization
- Individually developed, produced in series

Cycloidal gears and strain wave gears: The precision dream team
Cycloidal gears and strain wave gears complement each other perfectly and together form a real dream team for robotics & automation. If the larger axes of a robot or machine are equipped with cycloidal gears and the smaller ones in the end effector area with strain wave gears, the best possible precision can be achieved from the overall linking of all axes.

The most accurate robot in the world
More and more applications require the use of high-precision robots. With a Nabtesco add-on for robot control, it will be possible in future to increase robot accuracy by a factor of 9 and achieve a point or path accuracy of less than 0.1 millimeters. High-precision handling and machining tasks can thus be carried out robot-based with the precision of a machine tool. This offers maximum flexibility with the same quality.

We are consistently driving forward the digitalization of our precision gearboxes and offer unique solutions for networked, intelligent and automated production. Whether digital gearbox models, sensorized strain wave gears or hybridized cycloidal gearboxes: our innovative gearbox and drive concepts set standards on the market and open up unimagined possibilities in terms of productivity, efficiency, process reliability, maintenance and availability. Condition monitoring, predictive maintenance, digital gearbox twins, machine learning, big data and artificial intelligence (AI) are key buzzwords here.
