WS Series
The WS Series is a right-angle multi-stage planetary gearbox built for servo-driven equipment that needs backlash-free transmission, 90-degree power transfer, and reliable rigidity in limited installation space. Its hollow-through output shaft, solid shaft options, and five mounting faces make machine integration easier, while the cube-like housing suits low axial-load intermittent motion modules.
Key Points
- Backlash-free design
- 90-degree output layout
- Hollow / solid shaft options
- Five mounting faces
- High-rigidity structure
- WS42-1 to WS180-2

Product Description
- Backlash free.
- Hollow Shaft and Solid Shaft.
- Hollow output shaft design for various applications and 5 mounting surfaces for flexible installations.
- Arguably the easiest Right-Angle gearhead on the market to geometrically integrate into your machine. Rectangular "cube-like" geometry provides for easy fitting into your device. With 5 mounting surfaces, other components can be attached to the WS.
- Torque capacity: 1.25~42kgf*m(12.2Nm~411Nm).
