Gear made of plastic - extra light and low-wear

Every robot is as good as its gearboxes

In robots, robotic gears are the link between the motor, which supplies the drive energy, and a machine part that carries out a planned movement.

Gearboxes made of high-performance plastic: Lubrication-free, lightweight and shock-resistant
All drygear® joints are modular; they can be extended as required and integrated into existing systems. The drygear® gearboxes are particularly favoured for robot arms for quality control or sorting. But the gearboxes are also used for rotary axes or sliding applications.

    drygear test laboratory

    Tested and proven: individual customer tests in the drygear® test laboratory

    • Which gearbox is best suited for your application? What are the maximum loads possible?
    • What torque speed can be achieved?
    • What mechanical service life can I expect for my application?
    Around 50 in-house drygear® test stations are available for individual customer tests. We also test our gearboxes daily for active research and development.  

    Easy handling - operated manually or automatically

    Simple, fast and uncomplicated format adjustments. With the modular Apiro gearbox system, you can set up your own lane adjustment using different gear ratios and length variants.

    Assembly in minutes and simple replacement of gearboxes

    Connect stepper motors to robolink® joints.
    Replace motor with worm gear in a robolink® joint
