Actuators built for the humanoid era.
Integrated joint actuators and the precision gearboxes inside them. Motor, reducer, drive, and encoders in one housing, or the reducer on its own. Manufactured domestically, held in stock, and shipped with the CAD models and performance data engineers actually need.
- 420Nm
- Peak torque
- <1arcmin
- Backlash
- 2wk
- Lead time
- 100%
- US-made
Everything a robot joint needs, nothing it doesn’t.
Actuator or reducer
Drop in a complete A-Series joint, or design around the M-Series gearbox inside it. Same torque density, same CAD, one supplier either way.
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.
Motor, reducer, drive, and encoders. One housing.

Frameless PMSM, M-Series strain-wave reducer, integrated FOC drive, dual absolute encoders. CAN-FD and EtherCAT. <1′ backlash across the range.
The same reducer, on its own.

Building your own actuator? Every M-Series 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 actuator and gearbox ships with the files and characterization data you need to design it into a joint 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
- Motor constants, thermal limits & drive firmware docs
Order today. Build this week.
Tell us your torque, envelope, and ratio. We’ll send the matching actuator or gearbox, CAD, and a quote, usually the same day.
