Giant Precision's harmonic drive is zero to low backlash by design. It provides the highest level of transmission accuracy and can support a high ratio reduction in a single stage with minimal inertia. The highly accurate, torque-dense design makes harmonic drive the ideal solution for precision motion control applications.
Our Giant Precision Harmonic Drive range includes a wide variety of strain wave gearing options.
