💡 What is a shaft coupling used for in CNC machines and 3D printers?

It connects the motor shaft to the driven shaft while helping manage misalignment and vibration for smooth, reliable motion. Handy notes:

• Transfers torque between motor and driven shaft while tolerating small angular and parallel misalignments.
• Reduces vibration to extend bearing life and improve control precision.
• Easy to install with straight-line alignment and a secure fit for reliable performance.
• Choose a coupling with the correct bore size and material for your setup.
