Published Load / Shaft Limits¶
| Parameter | Public value |
|---|---|
| Radial load, 10 mm from flange | ≤ 0.6 kgf |
| Shaft axial load | ≤ 0.15 kgf |
| Radial shaft play | ≤ 0.04 mm |
| Thrust shaft play | ≤ 0.15 mm |
Only values currently published for 10P are shown. Do not transfer limits from another frame size.
Motor Matching Reference¶
- Adapted DC motor nominal voltage: 3–36 VDC
- Adapted DC motor power: below 3 W
These are motor-matching conditions, not electrical ratings of the mechanical gearbox.

Download 10P Simplified STEP - 4-Stage Reference
A simplified public 4-stage STEP reference is released for early packaging and mechanical Design-In. The detailed full-assembly STEP remains configuration-controlled and request-only because it contains internal planetary transmission geometry.
For final CAD, provide the selected ratio, stage count and motor interface.
