These coupling 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. The way they are cut, they are a little springy in the X Y & Z linear axis but not in the rotational axis. They are suitable for precision CNC work. This coupler will connect a 5mm diameter shaft to an 5mm diameter shaft.
