Rigid Shaft Coupler 5mm To 6.35mm Bore, 22mm Length, 14mm OD, Set Screw, Stainless Steel High Torque Motor Connector For 3D Printers, CNC Machines, Robotics, RC Boats, Cars, And Airplanes

Rigid Shaft Coupler with 5-6.35mm Bore, 14mm OD, 22mm length
✔️ Stainless steel rigid coupler, M4 screws, pack of 2, wrench included

This rigid shaft coupler is a high-torque, corrosion-resistant connection that securely joins two shafts in motion systems. It's ideal for 3D printers, CNC machines, robotics, RC crafts, cars, and airborne platforms where precise torque transfer matters.

✅ Bore range: 5-6.35 mm (0.20-0.25 in) with M4 set screws
✅ Outer diameter: 14 mm (0.55 in) and length 22 mm (0.87 in)
✅ Material: stainless steel for corrosion resistance
✅ Includes: 2 couplers, M4 hex wrench, 8 M4 screws

💡 What is a handy use case for a rigid shaft coupler in hobby projects?

This setup keeps shafts aligned and transfers torque cleanly. - It fits 5-6.35 mm shafts (0.20-0.25 in) - It minimizes backlash in motor-driven systems - It works well in 3D printers, CNC machines, robotics - It resists corrosion in harsh environments
