Key Features

  • For use with Martin Quadra-Flex series flexible couplings (sold separately)
  • Cast iron for non-corrosive applications where strength and heat dissipation are factors and weight is not
  • Meshes with S style spacers
  • Transfers shock and misalignment to the center element of the coupling assembly for reduced wear on the shaft assembly
  • Teeth help to distribute torsional load across the flange and sleeve, reducing wear and extending service life

Product Description

This Martin Quadra-Flex spacer coupling S style flange replaces flanges on Martin Quadra-Flex series flexible couplings, meshes with S style spacers, and is made of cast iron for non-corrosive applications where strength and heat dissipation are factors and weight is not. It transfers shock and misalignment to the center element of the coupling assembly for reduced wear on the shaft assembly, and its teeth help to distribute torsional load across the sleeve to reduce wear and extend service life. Martin Quadra-Flex couplings are suitable for use in applications requiring torsional flexibility and the capacity to withstand shock loads and vibration, including blowers, compressors, conveyors, dredges, feeders, generators, mills, and presses, 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.
