6mm To 6.35mm Aluminum Rigid Shaft Coupling With Set Screw Clamp, 20mm Diameter, 25mm Length, Easy Connect For Stepper Motors, CNC Machines, 3D Printers, And DIY Projects

Single unit aluminum coupling, 6mm to 6.35mm, 20mm dia
✔️ Clamping with set screw, recessed heads, anodized aluminum 25mm len

This rigid aluminum shaft coupling is designed to securely join motor and driven shafts in motion control systems. It's commonly used with stepper and servo motors in CNC machines, 3D printers, and DIY projects to ensure precise power transfer and stable alignment.

✅ Set-screw clamping for secure shaft connection and high axial load capacity
✅ Recessed screw heads create a smooth exterior and reduce snag risk
✅ Anodized aluminum body offers lightweight strength and corrosion resistance
✅ Fits 6mm to 6.35mm shafts with 20mm diameter and 25mm length

💡 What is a shaft coupling used for in motion systems? A handy device that connects two shafts to transfer torque while accommodating small misalignment. - Transmits torque between shafts with minimal backlash - Supports tiny angular and parallel misalignment to protect components - Reduces vibration and wear in drives like stepper motors and CNCs - Ideal for DIY projects, 3D printers, and encoder setups
