Flexible Jaw Shaft Coupling For 12mm To 15mm Bore, 40mm Diameter 45 Steel Motor Connector, High Torque Shaft Coupler For 3D Printers, CNC Machines, Servo And Stepper Motors

Flexible Jaw Shaft Coupling for 12-15mm Bore, 40mm Dia ✔️ 1 pc, 40mm Ø, 66mm long, fits 12-15mm bore, 45 Steel

This 45 steel flexible jaw shaft coupling connects two rotating shafts to transfer torque while compensating minor misalignments. It’s a common choice in precision equipment like 3D printers, CNC machines, servo systems, and stepper motor setups where alignment compensation and vibration damping matter. The polyurethane pad insert absorbs impacts and shields connected parts, helping extend service life. Installation is quick: align, slide onto the shafts, and tighten fasteners. Please verify the exact dimensions before purchasing.

✅ Material: 45 steel
✅ Outer Diameter: 40 mm
✅ Length: 66 mm
✅ Bore range: 12 mm to 15 mm
✅ Polyurethane pad insert for vibration damping
✅ Single-piece design; easy install and disassembly

💡 What is a flexible jaw shaft coupling used for in precision machinery? This handy connector transfers torque between motor shafts and driven components while damping misalignment. - Transfers torque between motors and driven loads in printers, CNC machines, and robotics - Compensates for small angular and axial misalignment to reduce wear - Dampens vibration with polyurethane pad to extend component life - 45 steel construction provides strong, reliable performance under load
