The drygear® planetary gearbox delivers precision motion for robotics, automation, and demanding industrial applications. Built with motion plastics®, it runs quietly and smoothly without external lubrication, so you eliminate maintenance and contamination risk. The compact design packs high power density and torque into minimal space, making it well suited where room is tight. You also get high ratio accuracy with minimal backlash and friction loss, and direct compatibility with a range of NEMA motors.
