Flexible Aluminium Coupling (8mm/8mm)

These couplers are made of machined aluminum 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 and well as any wobbling that may occur. There profile is such that they're a 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 two 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.
