Aluminium Bellow Coupling is most commonly used for connecting two components that displaces perpendicularly about their shafts. It has been designed with help of robotic arms and is made up of high quality stainless steel. One must know the right kind of torque to select accurate Aluminium Bellow Coupling according to need. This product has maximum torsional stiffness and are used application for high precision positioning. In maximum number of cases the coupling is rated according to maximum peak torque.
