8mm/5mm Flexible Aluminum Coupling with Plastic Insert

This flexible aluminium coupling connects an 8 mm shaft and a 5 mm shaft, for example the shaft of a Nema 17 stepper motor with a TR8 trapezoidal lead screw. A plastic insert in the core makes the coupling compliant, it compensates for small misalignments between the shafts and dampens shocks and vibrations. It is fastened with two M3 cap screws.

Recommended alternative in another version: 8mm/5mm Flexible Aluminium Coupling with Set Screws or 8mm/5mm Flexible Aluminum Coupling, for two 5 mm shafts: 5mm/5mm Flexible Aluminum Coupling with Pin Screws
