Lovejoy 05574 Size FA 3 Seal Component for Sier-Bath Flanged Sleeve Gear Coupling, Carbon Steel, Inch, 4000 Maximum Unbalanced RPM, 118000 in-lbs Nominal Torque

This Lovejoy FA Type O-ring fits a specific Sier-Bath flanged sleeve gear coupling (not included), and is suitable for use in assembling that coupling. The Buna-n O-ring seal is located between the sleeve and the flex hub to retain the coupling lubricant, and the O-ring seal has an operating temperature range of -40 to 100 degrees C (-40 to 212 degrees F). Gear couplings, a type of flexible coupling, use gear teeth on hubs and sleeves to transmit torque and offset rotational misalignment, and are suitable for use in applications involving extended distances between shaft ends, such as metal rolling mills and paper mills.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.Lovejoy manufactures flexible couplings, universal joints, variable speed drives, and other transmission and mechanical power products. The company, founded in 1900, is headquartered in Downers Grove, IL.
