Key Features

  • For use with Martin S and SC type flanges in the Quadra-Flex series flexible coupling assemblies (sold separately)
  • Thermoplastic polyester elastomer for high torque and high temperature applications
  • Two types: one piece (Type H) and two-piece held together with a metal retaining ring (Type HS) for applications where space limitations prevent the installation of a one piece sleeve
  • Teeth help to distribute torsional load across the sleeve and flanges, reducing wear and extending service life

Product Description

This Martin Quadra-Flex coupling sleeve is for use with Martin S and SC style flanges in the Quadra-Flex series flexible couplings. It is made of thermoplastic polyester elastomer for high torque and high temperature applications and its teeth help to distribute torsional load across it and the flanges, reducing wear and extending service life. This Quadra-Flex coupling sleeve comes in two types: one piece (Type H), and two-piece that is held together with a metal retaining ring (Type HS) for applications where space limitations prevent the installation of a one piece sleeve. Martin Quadra-Flex couplings are suitable for use in applications that require 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.
