Flexible Coupler (10mm to 14 mm)

From the shop's description

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 10mm diameter shaft to an 14mm diameter shaft. Comes with two sets of double set-screws (two per side) for secure attachment. d1 =10mm / d2 = 14mm Outer diameter (D): 32mm Length (L): 40mm
