Ihc 5-6mm ALUMINIUM FLEXIBLE SHAFT COUPLING COUPLER Electronic Components Electronic Hobby Kit

Couple 5mm shaft * 6mm shaft. 15 grams. -- 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 .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 a 5mm diameter shaft to an 6mm diameter shaft.
