5 mm to 5 mm Rigid Aluminium Shaft Coupling

This 5 mm to 5 mm rigid shaft coupling is designed to directly connect two shafts of the same diameter, providing backlash-free torque transmission between a motor and the driven component. It is intended for applications where both shafts are accurately aligned and a solid, non-flexible connection is required.

Machined from aluminium, it combines low weight with good mechanical strength, making it suitable for FDM 3D printers, light-duty CNC machines and other motion systems. Since it does not compensate for shaft misalignment, it should only be used where proper alignment between the motor shaft and the lead screw or driven shaft can be ensured.
