12mm to 8mm Jaw Type Flexible Coupling D40-L66 - Aluminum Shaft Coupler for Motor and Drive Connections

D40-L66 Aluminum Jaw-Type Coupler, 12→8mm Bore, Single Unit
✔️ 12mm to 8mm bore, 66mm long, 40mm OD, aluminum body

This jaw-type flexible coupling connects a motor shaft to a drive shaft, allowing slight misalignment while transmitting torque with minimal backlash. It's commonly used in compact machinery, CNC machines, 3D printers, and robotics where 12mm and 8mm shaft sizes are standard. This unit features aluminum construction for light weight and corrosion resistance, and it provides electrical insulation between halves.

✅ Bore compatibility: 12mm to 8mm (0.472 in to 0.315 in) jaw bore
✅ Length/diameter: 66mm long (2.60 in), 40mm diameter (1.57 in)
✅ Material + insulation: aluminum body with electrical insulation
✅ Performance: zero-backlash at low torque with misalignment tolerance

💡 What is a jaw-type flexible coupling used for in motor drive systems? This handy piece helps transfer torque between shafts with minimal backlash and tolerance for slight misalignment. - Smooth torque transfer in tight spaces - Accommodates angular and parallel misalignment - Lightweight aluminum body eases mounting and maintenance
