Beefy 20mm To 20mm Shaft Coupling Aluminum Rigid Clamping Shaft Coupler For Stepper Motor Servo CNC Machines And 3D Printers DIY Encoder With High Torque Capacity And Anodized Corrosion Resistant Finish

20mm to 20mm Aluminum Rigid Shaft Coupling - single unit
✔️ Aluminum 20mm to 20mm shaft coupling with high torque clamp

This aluminum shaft coupling securely links 20mm shafts, delivering a rigid, high-torque connection for stepper motors, servo drives, CNC rigs, and 3D printers. A recessed screw head keeps the surface flush for safety, and the anodized aluminum finish provides corrosion resistance.

✅ Material: anodized aluminum
✅ Shaft bore: 20mm to 20mm
✅ Screw type: coiling clamping
✅ High axial load and torque capacity
✅ Safety: recessed screw head reduces protrusion

💡 What is a shaft coupling used for in hobby CNC and 3D printer projects? - Torque transfer between motor and driven shaft
- Maintains shaft alignment and reduces vibration
- Suitable for 20mm to 20mm shaft connections on small CNCs, encoders, and printers
