RB NEMA 17 (42mm) Coupling 5×6.35mm

This RB NEMA 17 (42mm) 5×6.35mm coupling is compatible with almost all NEMA17 stepper motors. These couplings also known as Beam coupling, helical coupling, Flexible coupling. The RB NEMA 17 (42mm) 5×6.35mm coupling designed specifically with an Internal Bore Diameter of 5×6.35mm for the Motors having a shaft diameter of 5mm.  These couplings manufactured with high-quality Aluminum which makes them more sturdy and durable. Also, the use of aluminum material makes them much heavy and increases the strength of coupling. This Aluminium Helical Shaft coupling widely used in applications such as 3D Printers, CNC machines, and other DIY projects. Used to couple Stepper motors and 8MM rods / threaded rods/precision trapezoidal rods. The coupler takes care of small misalignments, deviations, and twists in the system.
