ZHR-H25: Integrated Harmonic Servo Joint Module
Quick answer: consider ZHR-H25 for precision motion where low backlash is the primary selection constraint. Validate the complete duty cycle, mechanical envelope and interface with engineering before release.
- Rated torque
- 27-91 Nm
- Peak torque
- 63-210 Nm
- Catalog weight
- 2.3 kg
