LOVEJOY's most versatile coupling, the LF series torsional couplings are constructed with an unique elastomeric element. It can easily integrate into a diverse range of coupling configurations, the LF series have a nominal torque up to 26,500 in-lb (3000Nm). To suit specific applications, the series are available in high temp rubber, Neoprene, Hytrel® or Zytrel® material essential for tuning critical system speed away from the application operating speed. The LF element can be axially or radially connected, to a flywheel adapter plate or flanged hub and a cylindrical center hub, respectively. The LF series' design is extremely simple and efficient, giving the LF torsional coupling high performance capabilities. Coupling selection should be approved with a system Torsional Vibration Analysis (TVA) (data needed to perform a TVA can be found inside the downloadable catalog).
