Gearboxes built for the humanoid era.
Compact, high-torque gearboxes engineered for robot joints. Manufactured domestically, held in stock, and shipped with the CAD models and performance data engineers actually need.
- 220Nm
- Peak torque
- <1arcmin
- Backlash
- 2wk
- Lead time
- 100%
- US-made
Everything an actuator needs, nothing it doesn’t.
Compact & high-torque
Strain-wave and planetary reducers with the torque density a humanoid joint demands. Sized to disappear inside the actuator, not dominate it.
Manufactured domestically
Designed, machined, and assembled in the United States. Short, resilient supply lines and no six-month overseas lead times.
In stock, shipped now
Core ratios and frame sizes held on the shelf. Prototype today and scale without re-qualifying a new part next quarter.
The data engineers need
STEP and native CAD, torque-speed curves, backlash, inertia, and efficiency data. Published up front, never requested under NDA.
One product line. Every frame size.
| Model | Ø mm | Ratio | Rated Nm | Peak Nm | Backlash | Mass g |
|---|---|---|---|---|---|---|
| M-14 | 40 | 50:1 | 9 | 28 | <1′ | 90 |
| M-17 | 50 | 80:1 | 24 | 54 | <1′ | 160 |
| M-20 | 62 | 100:1 | 45 | 110 | <1′ | 290 |
| M-25 | 78 | 100:1 | 92 | 220 | <0.5′ | 540 |
| M-32 | 98 | 120:1 | 178 | 420 | <0.5′ | 980 |
Every gearbox ships with STEP + native CAD, torque-speed curves, and full performance data.
The data engineers actually need, published up front.
No gated PDFs, no “contact sales for the model.” Every gearbox ships with the files and characterization data you need to design it into an actuator on day one.
- STEP (AP242) + native CAD models
- Torque-speed & efficiency curves
- Backlash, hysteresis & torsional stiffness
- Rotor inertia & full mass properties
- 2D drawings with GD&T callouts
- Bearing & lubrication life estimates
