5mm To 5mm Flexible Aluminum Couplings Set For NEMA 17 Stepper Motors And 3D Printers 5 Pieces RepRap And CNC Compatible Easy Install And Smooth Torque Transfer Durable Aluminum Alloy With Oxidation Finish Ideal For Reliable Motion

5x 5mm Aluminum Couplings for NEMA 17, 5pc
✔️ Aluminum alloy with oxidation finish, 5mm to 5mm, 25x19mm, 18g each

These flexible couplings are designed to transfer motion between shafts in small machines like RepRap 3D printers and compact CNC setups. They dampen misalignment and absorb shocks for smoother, more reliable operation.

✅ 5 pieces (5pc set) with 5 mm to 5 mm shafts
✅ Dimensions 25 mm x 19 mm (H x Dia.)
✅ Aluminum alloy with oxidation finish for durability
✅ Weight 18 g per piece
✅ NEMA 17 shaft compatibility (5 mm)

💡 What is a flexible coupling used for in small motion systems?

Handy for linking shafts while dampening misalignment and vibration in tight drives.

- misalignment tolerance and shock absorption - smooth torque transfer for stepper-based drives - easy install with 5 mm shafts in printers - protects motors and gear trains in small CNC setups
