Xynova PR43-120-600-HB Rotary Actuator
Every humanoid robot has a few joints that do most of the heavy lifting. When a full size robot stands up from a crouch, recovers from a stumble or lifts a load from the floor, the hips and knees carry torque that dwarfs anything in the arms. The Xynova PR43-120-600-HB is built for those moments. At 600 Nm of peak torque, it is the strongest joint module in Xynova's rotary lineup.
Key Features
600 Nm Peak Torque
The PR43-120-600-HB tops the Xynova rotary range at 600 Nm. That headroom matters for dynamic events such as jumping, catching a fall or pushing through sudden external loads, where a joint must briefly deliver far more than its everyday working torque.
43:1 Planetary Gearbox
Xynova designs its planetary gearboxes in house for high burst motion. The company highlights an optimized tooth profile and load balanced gear design intended to raise load capacity while reducing vibration and noise. The 43:1 reduction trades speed for torque, giving a no load output speed of 32 rpm.
High Resolution Feedback
A 17 bit encoder provides fine position feedback, and the module achieves repeatability of 0.15° or better. Xynova pairs this with a decoupled adaptive control architecture and AI driven parameter tuning, aimed at combining fast response with steady state accuracy.
Thermal and Structural Engineering
According to Xynova, the series uses electromagnetic and thermal co optimization, a proprietary motor winding process that raises slot fill, and integrated cooling channels to sustain high torque without overheating. Designs are validated through extensive CAE simulation and fatigue testing.
System Ready
Xynova supplies upper level software with a set of APIs for coordinating multiple actuators, and offers the module alongside its other rotary actuators, linear actuators and dexterous hands as part of a complete drive solution.

The PR43-120-600-HB and PR64-110-500 cover the high torque end of the range. The PR43 offers the most peak torque and a higher resolution encoder, while the PR64 is far lighter and more compact for applications where mass at the joint is the main constraint.
Applications
- Humanoid hips and knees: the highest load joints in full size bipedal robots.
- Waist and torso joints: supporting the upper body during bending, lifting and twisting.
- Heavy payload robot arms: shoulder joints that must hold or lift significant loads.
- Exoskeleton and assistive device research: high torque joints for lower limb prototypes.
- Legged robot development: large quadruped or bipedal platforms that need burst torque for dynamic motion.
Who Should Buy the PR43-120-600-HB?
Buy this module if your design needs the maximum available peak torque from a single Xynova joint, and the joint can accommodate a 4.3 kg, 120 mm diameter unit. It suits teams building full size humanoids, heavy lift arms and lower limb systems. If your joint sits far from the robot's center of mass, where every kilogram adds inertia, compare it with the lighter PR64-110-500.
Which Should You Buy?
| If you need... | Choose |
|---|---|
| Maximum peak torque | PR43-120-600-HB |
| High torque with the lowest weight | PR64-110-500 |
| Mid torque and higher speed for shoulders or elbows | PR21-100-140-HS or PR20-102-130-HS |
| A compact wrist or small arm joint | PRH19-57-25-HS |
Before You Buy
- Size continuous torque, not just peak: 600 Nm is a peak rating. Request Xynova's rated continuous torque and duty cycle data before final selection.
- Check speed requirements: the 32 rpm no load speed suits high load joints but may limit fast motions. Confirm your gait or motion profile.
- Plan the mechanical envelope: allow for the Ø120 x 126 mm body and request mounting interface drawings.
- Budget 48 V power: high torque joints draw significant current under load, so size your power system and cabling with margin.
- Confirm the HB variant: ask what the "HB" suffix includes in this configuration before ordering.
- Quote a full joint set: humanoid builds usually mix several models, so request pricing for every actuator together.
