12.7mm to 12mm Jaw Type Flexible Coupling D40-L66 - Aluminum Shaft Coupler for Motor and Drive Connections

12.7-12 mm Jaw Type Aluminum Coupling D40-L66 (1 pc)
✔️ Bore 12.7 mm to 12 mm, L 66 mm, aluminum body

This jaw-type flexible coupling connects a motor shaft to a driven shaft, providing a solid link while absorbing minor misalignment and vibration. It’s a popular choice for small motors, laser cutters, 3D printers, and compact CNC setups where easy installation matters.

✅ Bore1: 12.7 mm (0.50 in), Bore2: 12.0 mm (0.47 in)
✅ Length: 66 mm (2.60 in), Outer Ø: 40 mm (1.57 in)
✅ Aluminum construction with electrical insulation
✅ Zero-backlash at low torque; smooth torque transmission

💡 What is a jaw-type flexible coupling used for in motor drive systems?

A handy explanation follows, covering why this type of coupling is a smart choice for compact drive setups. - Transfers torque with minimal backlash in small drives - Compensates for slight angular and parallel shaft misalignment - Dampens twisting vibration while keeping installation simple
