CNC Shaft Coupler Flexible Plum Spider Jaw Coupling Stepper Motor Ø 35 40 45 mm Bore (d1×d2) & Amount (Pcs):12mm×12mm & 1 Pcs 05mm difference matters in precisionCNC Shaft Coupler Flexible Jaw Coupling Precision Motion for Stepper & Servo Motors When a rigid coupling transmits every vibration and micro misalignment directly into your motor bearings, precision suffers and components wear prematurely. Engineers and CNC builders who demand smooth, low backlash power transmission rely on flexible jaw couplings to absorb angular, parallel, and axial misalignment without sacrificing torque capacity. This flexible
