Aluminium Flex Shaft Coupler – 5mm to 8mm

The 5mm to 8mm Flexible Shaft Coupler joins shafts of different diameters while helping to compensate for minor misalignment, making it a great choice for CNC machines, stepper motor setups, and other precision motion projects.

Connect this to that with a set-screw coupler. These couplers are made of machined aluminium and have a spiral cut that makes them slightly flexible so they can be fit to two shafts even if they are not perfectly co-linear and will help reduce binding effects. The way they’re cut, they’re a little springy in the X Y & Z linear axis but not in the rotational axis. That means that you won’t get increased backlash – so they’re suitable for precision CNC work.

This coupler will connect a 5mm diameter shaft to an 8mm diameter shaft. A perfect add on for our stepper motors. Comes with two sets of double set-screws (two per side) for secure attachment. You’ll need a 2mm allen wrench to tighten/loosen the set-screws.

Please note: Stepper Motor is not included.
