Aluminium Flex Shaft Coupler - 5mm to 5mm

The 5mm to 5mm Flexible Shaft Coupler securely joins two 5mm shafts while accommodating minor misalignment, making it ideal for stepper motors, CNC machines, 3D printers, and other precision motion-control applications.

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 two shafts of 5mm diameter. 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.
