Positioning

Harmonic Drive Systems is the Japanese inventor and reference supplier of strain-wave gears (TSE:6324, ~JPY 60B class), whose core market is industrial robot joints (every major arm maker) with humanoid demand layering on top. It holds a near-monopoly in precision strain-wave gearing, though the NSK-NTN merger and a Chinese price attack (Leaderdrive) are recorded competitive threats. Revenue is 100-500m.
