Aluminum Alloy Coupling - 5x8mm, for 3D Printers (Blue)

Description       
3D Printer Aluminum Alloy Color Motor Coupling package contains of a color shaft motor coupling with optional standard diameter and length, which is made of aluminum alloy 6063 material and specialized for CNC machines, 3D printers, car models, RC metal model, etc. This coupling is a shaft coupler that is used to connect servo motor stepper motor, encoder screw driving machine platform, and so on. This coupler is simply designed with easy buffering, damping, and convenient connection and disconnection properties. This coupling is completely sized and has a smooth surface. The nominal coupler size is the size of two holes of the coupler, such as 5x8 that means in one end has a 5mm diameter hole to connect to a 5mm shaft and another end with 8mm hole diameter to connect to another shaft with 8mm diameter. Each coupling is equipped with 4 M4 machine screw for fastening the shafts in the coupling hole.
