CNC 8/8 flexible torsion coupling

Torsion coupling fi. 8/8 CNC flexible aluminum backlash-free Diameter: 20mm; Length: 25mmThe coupling consists of two hubs and a flexible coupling.Internal dimension of coupling 1; fi 8 mm are made in H7 classInternal dimension of coupling 2; fi 8 mm are made in H7 class. Precision backlash-free couplings for connecting drive screws to stepper motors, encoders, etc. They enable vibration-free torque transmission in machines.Backlash-free operation due to the torsional notch of the coupling. Attached coupling hubs is by twisting the coupling halves with an allen screw. The hubs have a cut made, tightening the allen screw tightens the hub.Backlash-free torsion couplings for connecting drive screws to stepper motors, encoders. Used in CNC machine drives.Couplings - are characterized by:small dimensions, low weight, low moment of inertia, high transmitted torque.
