Flexible Aluminium Coupling (5mm/8mm)

These Aluminum couplers 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. They area little springy in the X Y & Z linear axis but not in the rotational axis. That means you can enjoy flexibility without increased backlash making them suitable for precision CNC work. 

This coupler will connect 5mm to a 8mm diameter shafts together. 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 an allen wrench to tighten/loosen the set-screws.
