Huco 537.20.2424.Z Size 20 Flex-B Bellows Coupling, Stainless Steel with Aluminum Hubs, Inch, 0.25" Bore A, 0.25" Bore B, 0.79" OD, 1.22" Length, 19.736 in-lbs Max Torque

Description

This Huco Flex-B stainless steel bellows coupling with aluminum hubs is all metal and has a torsionally rigid design. The aluminum alloy hubs are treated with a clear anodized finish for resistance to corrosion, and the coupling's flexible bellows are spring quality stainless steel for strength, durability, and corrosion resistance. The joint assembly is composed of copper, heat-treated zinc plating, and black chromate, and the fasteners are made of black-oiled alloy steel for strength and corrosion resistance. This bellows coupling can operate in temperatures ranging from -40 to 248 degrees F (-40 to 120 degrees C) and is commonly used in applications that require high torsional stiffness and torsional integrity. The coupling is suitable for use with encoder drives, closed loop servo systems, pulse generators, and metering valves, 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.Huco Dynatork manufactures couplings, piston air motors, brakes, clutches, gear boxes and other transmission products. The company, founded in 1965, meets the quality assurance standards of the British Standards Institution (BSI), the International Organization for Standardization (ISO) and the Deutsches Institut für Normung (DIN), and is based in Hertfordshire, England.
