💡 What is a handy use case for a 12-17mm bore flexible coupling shaft in CNC and robotics?

It's handy for connecting motors to loads where perfect alignment isn't possible.

- Reduces stress between motor and driven components

- Absorbs minor misalignment and vibration for smoother torque transfer

- Easy to mount with standard M6×1.0 threads and compatible bores
