5-8mm ALUMINIUM FLEXIBLE SHAFT COUPLING 5MM TO 8MM

• Bore Diameter(D1)=5mm, D2=8mm
• Exhibits good strength.
• High-grade aluminum couplings.
• Weight 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 8mm diameter shaft.
