Disc coupling consists of two or more hubs and multiple disc modules, which are divided into single disc and double disc types, fixed by clamping screws, elastic compensation for radial, angular and axial deviations, and large torque , low inertia, high rigidity, high sensitivity and other characteristics, the durability and corrosion resistance of the coupling are greatly improved through special surface treatment. Hubs are available in 7075 material and 45# steel material, and Disc is made of SUS304 material. Suitable for servo motors and stepper motors.
