5mm To 6mm Shaft Coupling, Beefy 25mm Length, 20mm Diameter Aluminum Alloy Coupler For Stepper Motors, CNC Routers, And 3D Printers, 6061-T6 Anodized Finish, High Torque, Axial Load Capacity Built To Last
✔️ 5-6 mm bore to 20 mm shaft, 25 mm long, anodized aluminum
This rigid aluminum shaft coupling connects a 5-6 mm shaft to a 20 mm drive shaft, delivering tight, backlash-free torque in compact spaces. It's a single-unit solution ideal for hobby CNC machines, 3D printers, and small servo or stepper motors where precision matters.
✅ 6061-T6 aluminum alloy with anodized finish
✅ H7 bore tolerance with go/no-go inspection for zero backlash
✅ 20 mm outer diameter, 25 mm length for compact mounting
✅ High torsional stiffness and high axial load capacity
✅ Suitable for stepper motors, CNC routers, spindles, encoders, and 3D printers
💡 What is a shaft coupling used for in precision motion control systems for CNC machines and 3D printers?
This handy component helps keep torque aligned and reduces misalignment wear, boosting accuracy. - precise torque transfer with minimal backlash - supports minor shaft misalignment during high-speed rotation - reduces bearing load and extends motor life
