Strain Wave Gear Design
Patented strain wave gearing using flexspline and wave generator technology achieves true zero-backlash performance. The elliptical wave generator deforms the flexspline to engage with the circular spline for smooth, silent operation.
Exceptional Torque Density
Strain wave gear design delivers up to 3,000 Nm output torque in a remarkably compact package. The unique flexspline design provides high reduction ratios (30:1 to 160:1) in a single stage.
Zero-Backlash Reliability
True zero-backlash performance with no maintenance degradation over time. Ideal for collaborative robots, medical robotics, and precision positioning systems requiring absolute repeatability.
