LV Series Torsional Coupling

The LV Series coupling is designed and built for diesel engine driven equipment such as agricultural and offroad equipment using universal joint drive shafts. The LV Series is ideal for universal joint driven equipment applications as well as other arrangements. The LV Series couplings are highly torsionally compliant, allowing the engine to drive a large inertia load safely away from damaging torsional resonance and critical speeds. The coupling selection should be verified with a Torsional Vibration Analysis of the system.

  • Economical alternative for agricultural & off-highway industrial equipment
  • Designed for mounting on standard SAE J620 flywheels
  • Available in high temp rubber (HTR) or EPDM
  • Nominal torque: up to 10,820 in-lb (1223 Nm)
