💡 Why pick a flexible coupling shaft for servo motors in CNC setups?

A handy explanation: it minimizes stress and vibration between motor and driven parts.

- Improves torque transfer by absorbing minor misalignment - Reduces wear on bearings and encoders - Supports 15-25 mm bore systems with M6/M8 thread options
