  • Static Breaking Torque is not a recommended operating torque.
  • Square and hex bores are measured across the flats.
  • Operation of all universal joints is determined by the angle/speed combinations of the application. Consult Lovejoy Engineering for specific limitations and recommendations.
  • Applications that fall outside the limitations of these tables should be referred to Lovejoy Engineering for assistance.
