A selection of Inserts Three Jaw Type Couplings. Match with Three Jaw Type hubs by OD

  • Mechanical coupling that connects two shafts to transmit torque while also damping vibrations and accommodating misalignment.
  • Consists of two metallic hubs with jaws and a flexible elastomeric insert, called a element that sits between them.
  • The jaws of the hubs fit alternately with the lobes of the element to transfer torque.
  • Use Bost-Bronz inserts for high torque loads at slower speeds
  • Use rubber for quiter operation
  • Use polyurethane for moderate to heavy shock loads
