The gearbox technology

Gearboxes are used to adapt the speed and torque of motors so that they are suitable for the specific requirements of machines and processes.

Our drygear® gearboxes made of high-performance plastic: lubrication-free, lightweight and impact-resistant
All igus® plastic gearboxes are modular; they can be extended as required and integrated into existing systems. The drygear® gearboxes are especially popular for robot arms used in quality control or sorting. Gearboxes also come into play with rotary axes or sliding applications, pusher applications or format adjustments.Our gearboxes are the ideal solution for various automation processes.

Advantages of the drygear® gearbox technology



Manufacturing with injection moulding or 3D printing guarantees cost efficiency and creates the geometrical freedom to optimise use of installation space. The flexible modular system allows the gearboxes to be expanded as desired and integrated into existing systems. 

Lubrication and maintenance-free

Lubrication-free drygear® gearbox technology uses plastic gears made of high-performance polymers. The gearboxes require no external lubricants, so they are resistant to dirt. No maintenance is necessary, so associated costs are eliminated.


Sustainability Our gearboxes require not a single drop of lubricating oil. This benefits not only our users, but also the environment. Our tribologically optimised materials also generate less abrasion, which means less energy is needed.



Thanks to motion plastics®, drygear® plastic gearboxes impress with ultra-light materials. This results in much less noise and vibration. For you as an operator, plastic gears - for example in robots - lead to an application that is up to four times quieter. 


Temperature Gearboxes that function reliably in either particularly warm or cold environments? The drygear® gearbox technology products can withstand almost all conditions. We also have gearboxes and motors in our product range that are suitable for extreme temperatures from -30°C to +180°C. 

Tested and proven

Icon tested Around 50 in-house drygear® test stations are available for individual customer tests. We also test our gearboxes daily for active research and development.
