14mm to 8mm Jaw Type Flexible Coupling D40-L66 - Aluminum Shaft Coupler for Motor and Drive Connections

The D40-L66 jaw-type flexible coupling connects motors to drives with 14 mm and 8 mm shaft bores. Made from aluminum, it delivers lightweight torque transfer with minimal backlash, tolerates small angular misalignment, and dampens twisting vibration in CNC machines, robotics, and automation setups. Ideal for hobbyists and compact machines needing a reliable shaft connector.

✅ Bore 1: 14 mm, Bore 2: 8 mm, Length: 66 mm, OD: 40 mm
✅ Material: Aluminum, lightweight yet rigid
✅ Zero-backlash at low torque and smooth torque transfer
✅ Electrical insulation enhances safety in mixed-signal environments
