CNC 12.75/12.75 flexible torsion coupling

Torsion coupling fi 12,75/12,75 CNC flexible aluminum backlash-free Diameter: 30mm; Length: 35mmThe coupling consists of two hubs and a flexible coupling.Internal dimension of coupling 1; fi 12,75 mm are made in H7 classInternal dimension of coupling 2; fi 12,75 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 , by tightening the allen screw we tighten the hub.Torsion couplings backlash-free for connection of drive screws with stepper motors, encoders. Used in CNC machine drives.Couplings - are characterized by:small dimensions, low weight, low moment of inertia, high transmitted torque.
