19mm To 20mm Plum Flexible Shaft Coupling With 40mm Diameter And 66mm Length Aluminum Motor Connector Flexible Spider Pro Grade Coupler For 3D Printers CNC Machines And Servo Stepped Motors With Heavy Duty Vibration Damping And Anti Abrasion

Plum 19-20mm shaft coupling, 40x66mm (1.57x2.60 in)
✔️ Size: 40mm dia x 66mm L, bore 19-20mm (0.75-0.79 in), 1pc aluminum

This plum shaped flexible shaft coupling is used to join motors to driven shafts in 3D printers, CNC machines, and servo or stepper setups. It dampens vibration and handles minor misalignment in tight spaces.

✅ Size: overall 40mm diameter, 66mm length, bore 19-20mm
✅ Material: aluminum alloy body with polyurethane spider for damping
✅ Locking: clamp-on bore, through bore, supports high torque
✅ Applications: for servo motors, step motors, printers, CNC routers

💡 What is a shaft coupling and why would you choose a plum flexible type? This handy piece connects motors to driven shafts while damping vibration.

- Handy for smoothing drive trains in printers, mills, and CNC rigs - Dampens vibration and compensates small shaft misalignment - Handles high torque without binding in tight spaces - Quick, clamp-on installation makes setup easy
