This Martin Universal series coupling half replaces coupling halves on Martin Universal (ML) series jaw style flexible couplings and is made of stainless steel for strength, durability, and corrosion resistance. It transfers shock and misalignment from the shaft to the center element of the coupling assembly for reduced wear on the shaft assembly and flexes up to one degree to compensate for angular misalignment of coupled shafts. This coupling half is resistant to moisture, oil, grease, and contaminants such as dirt and sand, and has an operating temperature range of -45 to 210 degrees F (-42 to 99 degrees C). Martin jaw style couplings are suitable for use in various industrial power transmission applications, including compressors, blowers, pumps, conveyors, mixers, and gear boxes, 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.Martin Sprocket & Gear manufactures power transmission and conveying products. Martin provides tools that meet American National Standards Institute (ANSI), National Aerospace Standard (NAS), and Deutsches Institut für Normung (DIN) standards. The company, founded in 1951, is headquartered in Arlington, TX.
