HD-650 Torsionally Rigid Double flex coupling With Bore and Keyway
HD-650 torsionally rigid double flex coupling with bore and keyway is ideally suited to applications in which the positioning accuracy of the control system in both directions is important. GERWAH® couplings are maintenance-free and do not require greasing or cleaning. Due to the very strict production tolerances, GERWAH® allows precise vertical alignment and a high level of true running accuracy, making it ideal for applications involving high speeds even with irregular rotary forces. The design of the coupling guarantees a high level of torsional stiffness, which is an important property for applications in packaging machines, servomotors drives, printing presses and machine tools.
