What the Company Makes
A strain wave gear is a compact reduction gear with very little backlash, which means it positions precisely and suits the confined space of a robot joint. Harmonic Drive Systems specializes in this one technology and supplies it for several uses.
Application | Note |
Industrial robot joints | The largest use |
Semiconductor equipment | Wafer handling and similar precise motion |
Medical devices | Surgical and imaging equipment |
Machine tools | Precise positioning axes |
Satellites | Space mechanisms |
Automotive | Selected applications |
Alongside the gears themselves the company sells mechatronics products, meaning actuators and control devices that combine a gear with a motor and sensor.
