CSG/CSF-2UH series harmonic drive units are available in ten sizes with gear ratios from 50:1 up to 160:1, offering repeatable peak torques from 23 to 3419 Nm. The output bearing with high tilting rigidity enables the direct introduction of high payloads without further support, permitting simple and space-saving designs.

Standard servo motors can be attached in a compact manner. The harmonic drive gearboxes cover a wide torque range and feature long service life, confirmed by many years of successful service. Unit and motor together form a compact and lightweight system capable of quickly withstanding high loads. Due to the units' positioning accuracy, stable machine characteristics with short cycle times are guaranteed.

Difference between CSG series and CSF series is that CSF series harmonic gearbox is with standard torque, while CSG series harmonic gearbox is with higher torque and longer service time.

Frequently Asked Questions

🔵 What is the main difference between CSG and CSF series?
The CSG series is designed for high-torque applications. It offers 30% higher torque capacity and a 43% longer service life (up to 10,000 hours) compared to the standard CSF series.
🔵 Does the harmonic drive have any backlash?
No, these harmonic drive units are designed for zero backlash, ensuring extreme precision and repeatable positioning accuracy for robotic and CNC applications.
🔵 What gear ratios are available for the CSG series?
Standard available gear ratios include 50:1, 80:1, 100:1, 120:1, and 160:1 to suit various speed and torque requirements.
🔵 Can these gearboxes support high payloads directly?
Yes, the integrated output cross roller bearings provide high tilting rigidity, allowing for the direct support of high payloads without the need for additional external bearings.
🔵 What are the typical applications for these reducers?
They are primarily used in industrial robot arms (5-axis or 6-axis), precision medical equipment, semiconductor manufacturing systems, and high-precision positioning tables.
🔵 Are they compatible with standard servo motors?
Yes, the units are designed to be attached to standard servo motors in a compact manner. Specific motor mounting details can be confirmed based on your motor model.
