Connect motor shaft to anything else with a set-screw coupler. 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 bending effects.
The way they are cut, create a spring effect in the X Y & Z linear axis but not in the rotational axis. That means that you will not get increased backlash - so they're suitable for precision CNC work.
This coupler will connect a 6mm diameter shaft to an 8mm diameter shaft. Comes with two sets of double set-screws (two per side) for secure attachment.
- d1=6mm / d2= 8mm
- Outer diameter (D): 18mm
- Length (L): 25 mm
