Two Pack Flexible Shaft Couplers 4 To 6.35mm Bore 20mm Long 15mm Diameter Aluminum Alloy Joint Connector For Stepper Motors Ideal For 3D Printers CNC Machines DIY Encoders And Transmission Projects

Two Pack Flexible Shaft Couplers for 4 to 6.35mm Bores
✔️ Two pack anodized aluminum 15mm OD by 20mm long couplers

These shaft couplers connect two shafts to transmit power and torque in motion systems like stepper motor setups on 3D printers and CNC machines.

✅ Made from heat resistant anodized aluminum alloy
✅ 15mm outer diameter 20mm length with 4 to 6.35mm bore range
✅ Annular groove design adds flex and reduces vibration
✅ Clamping screws keep alignment tight under load

💡 What is a shaft coupler used for in motion control systems? Shaft couplers link motor shafts to driven components so power transfers smoothly without misalignment issues. - They work well in 3D printer frames where stepper motors drive lead screws or belts - CNC machines and encoders rely on them for accurate torque delivery - The flexible style absorbs small shocks to protect both motor and connected parts - Install by sliding onto the shaft ends then tightening the set screws for a secure hold
