Working Mechanism

  • As one shaft begins to rotate, the curved jaws within the coupling securely engage one another, enabling the efficient transfer of torque from one shaft to the other. This, in turn, facilitates the transmission of power and motion between the shafts.
  • The jaw coupling hub consists of dual sets of curved jaws, with one set affixed to each shaft. These jaws seamlessly interlock with each other when the hub is mounted onto both shafts, ensuring a reliable connection.


  • This Lovejoy L150 coupling hub is equipped with a keyway for precise alignment and a stainless steel bore, which enhances corrosion resistance and longevity.
  • It further features keyway finish and stainless steel finish, ensuring a smooth and precise fit.
  • This Lovejoy L150 coupling hub features iron construction for high strength and structural rigidity.
