This flexible motor coupler, also known as helical coupler, is a flexible coupling for transmitting torque between two shafts while allowing for angular misalignment, parallel offset and even axial motion, of one shaft relative to the other. This High Quality, Aluminium Helical Shaft coupling is commonly used in 3D Printers, CNC machines and other DIY projects to couple Stepper motors and rods, threaded rods, precision trapezoidal rods. The coupler takes care of small misalignments, deviations and twists in the system. This motor coupler features zero backclash. The bore diameters of this coupler are 4 mm and 4 mm. This coupler works with 4 mm and 4 mm shafts.
