5Mm To 10Mm Aluminum Beefy Shaft Coupling Flexible Coupler 25Mm Long 19Mm Outer Diameter For Stepper Motors Encoders 3D Printers CNC Machines DIY Projects Silver

Aluminum Flexible Shaft Coupling 5mm to 10mm Stepper Motors
✔️ Aluminum alloy spring-type coupling, 25mm, 19mm OD, 5mm to 10mm bore

This spring-loaded aluminum shaft coupling provides a flexible, buffered link between motors and driven shafts. It’s a common choice for stepper motors, encoders, 3D printers, and CNC machines, helping absorb small misalignment and shaft deviations in precision drives.

✅ Bore: 5 mm to 10 mm (0.20 in to 0.39 in) bore compatibility
✅ Outer diameter: 19 mm (0.75 in)
✅ Length: 25 mm (0.98 in)
✅ Material: aluminum alloy, spring-type buffered design
✅ Includes 1 hex wrench in the package

💡 What is a handy use case for this coupling in hobby CNC projects? This helps buyers see why it matters in real setups. - It absorbs minor misalignment and shaft deviations to extend bearing life. - It buffers torque spikes from stepper motors and encoders to reduce vibration and wear. - It fits 5 mm to 10 mm bores and 19 mm outer diameter, covering common hobbyist setups.
