Ultra-flat, high-torque density, and standard harmonic reducers for robotics, cobots, and aerospace applications with tight backlash and sub-arc-minute lost-motion requirements.
| Metric | Typical Range | Why It Matters |
|---|---|---|
| Backlash | Near-zero to <1 arc-min, model-dependent | Critical for cobots and precision equipment where lost motion destroys path accuracy. |
| Reduction Ratio | 30:1 up to 320:1 | Harmonic drives achieve extreme ratios in a single stage, saving significant space and weight. |
Public Selection Matrix
Use this matrix to identify the right engineering review path before requesting model-specific CAD, drawings, or a drop-in replacement check.
| Subseries | Scope | Public Specs to Check | Buyer Use |
|---|---|---|---|
| Ultra-flat strain-wave reducer | Short axial-length harmonic-style reducers for compact robot joints, medical automation, and slim rotary axes. |
| Use this family when the mechanical package is extremely shallow and output precision still matters. |
| High torque density strain-wave reducer | High-ratio strain-wave reducers with alloy flexspline options and high repeated torque density. |
| Use this family when payload and ratio requirements exceed a standard compact harmonic reducer. |
| Standard cup or hat reducer | General robot joint harmonic-style reducers with cup or hat configuration and motor-side wave generator options. |
| Use this family for robot arms, collaborative automation, and compact rotary stages with known interface drawings. |

STEP, IGES, SolidWorks, 2D PDF on request
Use the no-login worksheets before sending drawings or requesting model-specific CAD. They help engineering confirm torque, backlash, interface, inspection, and replacement assumptions for Precision Harmonic Drive Reducers.
Yes, our standard, flat, and high-torque series match the exact pilot diameters, bolt circles, and spline interfaces of major incumbent brands.
We supply both bare component sets (for deep OEM integration) and fully housed gear units with integrated heavy-duty cross-roller bearings.
