GSL Series Zero-Backlash Strain Wave (harmonic) Gearboxes
GAM’s GSL series zero-backlash strain wave (harmonic) gearboxes provide zero-backlash and high torque in a small, lightweight gearbox. Collaborate with GAM engineers to customize the GSL series robotic strain wave gear reducers for easy integration into machines and mechanisms.
Features
- Drops in for popular competitor gearboxes
- Strain wave (harmonic) gearing for high precision
- Backlash ≤ 0.5 arcmin (≤ 30 arcsec)
- High reduction ratios in a single stage: 50:1 to 160:1
- Simple design for integration into a mechanism or machine
- High torque density with low inertia
- Wide selection of models and configurations
- Collaborate with GAM engineers to design a strain wave gearbox assembly for easy integration

The terms "Cup" and "Hat" refer to the shape of the Flexspline. When viewed in cross-section, the flexspline looks like a cup or a hat.
Cup Style
Mounting flange output (bottom of the cup) is easy to bolt to for components such as pinions
Hat Style
The flexspline is outermost diameter. Useful for applications requiring a gearbox with a rotating housing such as an AGV wheel or robot joint
Rotation Direction
The GSL strain wave gearbox can be driven in two ways:
Common Operation
Input | Wave Generator |
Output | Flexspline |
Fixed | Circular Spline |
Rotation | Opposite Direction |
Ratio | Nominal Ratio, e.g. 50:1 |
Alternate Operation
Input | Wave Generator |
Output | Circular Spline |
Fixed | Flexspline |
Rotation | Same Direction |
Ratio | Nominal Ratio + 1, e.g. 51:1 |
