A flexible aluminium coupling is a mechanical component that is used to connect two shafts together and allow them to transmit rotational power while also allowing some degree of misalignment between the shafts. The coupling is typically made of aluminium and has a flexible element, such as a rubber or plastic insert, that allows it to accommodate misalignment. Flexible couplings are used in a variety of applications where it is necessary to transmit power between two shafts that may not be perfectly aligned. The 5mm x 5mm size refers to the diameter of the shafts that the coupling is designed to fit. This size of coupling is commonly used in small to medium-sized applications where a compact and lightweight coupling is desired. Use this coupler to connect 5mm-to-5mm shafts such that of a Nema17 motor
