Gearheads
Nexen’s revolutionary Harmonic Gearhead (HG) is the ideal combination of size and precision. The Harmonic Gearhead integrated with Nexen’s Roller Pinion System creates a true backlash-free solution from the motor to the driven load, delivering high load capacity in a compact package.
With up to a 70% reduction in length over standard gearheads, machine designers have greater opportunities available with this space-saving product.

Gearheads are a replacement for non-rigid, bulky, high-ratio gearboxes. Utilizing zero-backlash strain wave technology for maximum system rigidity and space-saving allows for the Harmonic Gearhead to:
- Operates in less than half the space
- Zero backlash directly to the motor
- Quiet operation
- Output torque up to 1,057 Nm
- Thrust up to 6,000 N on units with integrated pinion output
- Rotational accuracy of ± 45 ArcSec and linear accuracy of ± 25 μm on units with an integrated pinion on the output
- Rotational repeatability of ± 10 ArcSec and linear repeatability of ± 7.5 μm on units with an integrated pinion on the output
- Rugged cross-roller output bearing supports moment loads up to 1,590 Nm
Applications
Nexen’s Gearheads are ideal for applications like:
- Aerospace
- Robotics
- Semiconductor
- Factory Automation
- Medical/Surgical
- Machine tools
- Robots and robotic arms
- Rack and pinion systems
- General industrial positioning
