1pcs BR 9.5mmx12.7mm D30L42 CNC Motor Shaft Coupler 9.5mm to 12.7mm Coupling connect servo motor stepper motor encoder

BR series flexible coupling Body Material: Aluminum Alloy Rated Torque(N.m) :1N.m Max torque: 2N.m Eccentricity error: ¡€0.2mm Shaft angel ¡œ 2¡£ Max Rotational (rpm) :19000 Rated: In-phase operate D=30 L= 42 (Special bore size and slot available on request) Flexible couplings are used to transmit torque from one shaft to another when the two shafts are slightly misaligned. Flexible couplings can accommodate varying degrees of misalignment up to 3¡£. In addition to allowing for misalignment, flexible couplings can also be used for vibration damping or noise reduction.
