Strain Wave gearboxes

Nabtesco Harmonic Drive (Strain Wave Gear) – Precision Wave Gears
Nabtesco’s innovative strain wave gear technology – also known as harmonic drive and developed by Ovalo GmbH – delivers revolutionary precision and zero-backlash operation in industrial motion control. These compact units provide absolute repeatability and high torque transmission even in small sizes, ensuring torsion-free performance.
Available in sizes from 35 to 102 and gear ratios ranging from i = 30 to 160, the systems come in both hat-type (HTG) and cup-type (CTG) designs – including hollow-shaft plug & play versions.
The torque range spans from 7 Nm up to 28,000 Nm, making these drives suitable for a wide array of applications from robotic joints to AGVs, positioning systems, and even medical devices.

• 0% backlash, excellent repeatability
• Compact and lightweight design with single-stage high-ratio reduction
• Up to 28,000 Nm torque across the full range
• Modular and application-specific configurations – sensors and electronics can be integrated
• Automotive-grade quality, rapid production, and cost-effective performance

Discover how Nabtesco’s harmonic drives elevate the precision, reliability, and performance of your machines and systems – where the gear adapts to your needs, not the other way around.
