Product feature
- High Precision:Featuring ultra-low backlash with transmission play under 1 arc-minute.
- Low Noise, Low Vibration, High Efficiency:Its distinctive continuous rolling contact paired with a crank-cam design minimizes meshing failures and fatigue damage, while a linear structure enhances torque rigidity.
- Enhanced Sealing Design:Offering a broad range of reduction ratios from 19 to 5000 (partial customization available).
- Ease of Assembly:The integrated input support and sealed output design facilitate straightforward installation.
- Low Input Inertia, High Dynamic Response:The first-stage planetary gear configuration diminishes input inertia, thereby enhancing the servo motor’s responsiveness.
- Superior Power Transmission:Its unique continuous rolling contact coupled with a crank-cam structure minimizes meshing failures and fatigue damage, while a linear design bolsters torsional rigidity.
- Torque Range:19 Nm to 40,000 Nm (partial customization available).
- Lifetime Lubrication-Free:Pre-charged with specialized lubricating grease at the factory, ensuring maintenance-free performance throughout its lifespan.
Naming Convention

Rated Parameters
- CK is designed mainly as intermittent periodic duty. For continuous operation duty application, those series should not exceed 60% (max. 70%) of rated output torque and maximum output speed on the specifications or CK surface temperature should be settling within max. 80°C.
- Rated output torque and rated output speed is set for life time as 6000 hours. (Refer CK model selection.)
- Even though output torque raised by life time calculation, due to the fact, output speed is low, it should not exceed maximum average output torque.
