This Huco Flex-M flexible membrane double stage coupling with spacer and clamp style fixing is suitable for use in high rotational speed applications. The aluminum alloy hubs and spacer are treated with a clear alocrom finish for resistance to corrosion, and the coupling's membranes are heat-treated spring quality stainless steel for strength, durability, and corrosion resistance. The fasteners are made of black-oiled alloy steel for strength and corrosion resistance. This flexible membrane coupling can operate in temperatures ranging from -40 to 212 degrees F (-40 to 100 degrees C) and is commonly used in applications that require high rotational speeds and the ability to minimize excess movement due to misalignment. The coupling is suitable for use with rolling mills, turbine-driven gearboxes, and compressors, among others.

Flexible couplings are used to link two rotating shafts that are not aligned in order to transmit the rotational power, known as torque, from one shaft to the other. Most flexible couplings consist of two hubs and a middle assembly; each hub attaches to a shaft while the middle assembly flexes between the hubs to accommodate the misalignment of the two shafts. Shaft misalignments are generally either parallel or angular and cause complications to transmitting rotational power from one shaft to another in the form of stresses, loads, vibrations, and other forces, which vary from one type of misalignment to another. Flexible couplings are used in a broad range of applications, such as in motor vehicles, conveyors, escalators, agricultural, forestry and mining equipment, aeronautics, robotics and space exploration, among others.
