12.7mm To 15mm Shaft Coupling 45mm Long 32mm Diameter Aluminum Alloy Joint For 3D Printer CNC Machine DIY Encoder Screw Clamp Flexible Motor Coupler For No Fuss Smooth Power Transfer

Shaft Coupling: 12.7-15mm to 15mm for smooth power transfer
✔️ 12.7-15mm shaft, 45x32mm, aluminum alloy, screw clamp, single piece

This compact shaft coupling connects motor shafts to driven shafts in small CNC machines, 3D printers, and encoder-driven systems, delivering reliable, low-backlash power transfer.

✅ 12.7-15mm shaft usage diameter
✅ 45x32mm size (LxD); 1.77x1.26 in
✅ Aluminum alloy, silver tone
✅ Set screw clamping (coiling) type, zero backlash
✅ One-piece metallic spring coupling
✅ Absorbs parallel and angular misalignment and shaft end-play

💡 What is a handy question about shaft couplings in hobby CNC and 3D printers?

Answer: Shaft couplings help align shafts and damp backlash for smoother motion in small drive systems.

- improves torque transfer between motor and driven shaft - absorbs parallel and angular misalignment - reduces end-play and vibration in light-to-medium torque drives - suitable for encoders, lead screws, and small pumps ✝️
