💡 What are high-ratio strain wave gear reducers used for in precision motion systems?
High-ratio strain wave reducers are chosen when maximum torque and fine positioning control are required.

- Helps handle heavy loads with stable motion
- Improves positioning accuracy in servo-driven systems
- Keeps backlash low during repeated movements

This 120:1 CS-20 reducer is a handy option for high-load, high-precision motion control.
