19mm to 12.7mm Jaw Type Flexible Coupling D40-L66 - Aluminum Shaft Coupler for Motor and Drive Connections

D40-L66 Aluminum Jaw-Type Coupling, 19→12.7mm, Pack 1
✔️ 40mm aluminum housing, bore 19mm to 12.7mm, 66mm long

This jaw-type flexible coupling in aluminum links motors and driven shafts, ideal for low to mid torque drive systems. It absorbs angular, parallel, and axial misalignment and dampens vibration, making it common in automation, CNC, and robotic setups.

✅ Outer diameter 40 mm; bore sizes 19 mm and 12.7 mm; length 66 mm; aluminum
✅ Tight fit provides zero backlash at low torque
✅ Handles angular and parallel misalignment with damping
✅ Electrical insulation for safe motor connections

💡 What is a jaw-type flexible coupling used for?

- handy for motor to load connections with mild angular misalignment - reduces vibration and protects bearings in light to medium torque setups - perfect for hobby CNC, 3D printers, and automation projects - aluminum construction offers light weight and corrosion resistance
