Durable Aluminum Shaft Coupler 6mm to 6mm for Stepper Motors, 25x18mm Joint Connector With Set Screws, Aluminum Alloy, 2 Pack For 3D Printers And CNC Machines, Encoder Ready, Flexible Link For DIY Projects By Xnrtop

Durable 6mm to 6mm Aluminum Shaft Couplers, 2-Pack
✔️ 6mm to 6mm shaft, 25x18mm, set-screw clamping, aluminum alloy

These compact aluminum shaft couplers connect 6mm shafts in small CNC machines and 3D printers. They absorb minor misalignments, reduce motor stress, and provide smooth torque transfer for reliable Z-axis and drive-system performance.

✅ Size: 25x18mm (LxD), 6mm bore to 6mm bore
✅ Material: aluminum alloy, silver tone
✅ Type: set screw clamping, zero backlash
✅ Includes 2 couplers, encoder-ready and lightweight

💡 What is a shaft coupling used for in motion control systems? A handy connector that transmits torque while absorbing misalignment to protect motors in lightweight drives.

- Transfers torque smoothly and provides a handy, low-backlash solution for CNC printers - Absorbs small angular and parallel misalignment, reducing motor wear and vibration - Ideal for encoders, lead screws, and light to medium duty drives
