Features

  • The standard, industrial-type universal joint features a pin-and-block design and boot-retaining grooves.
  • D-type universal joint features a special tapered shape of the yoke, providing exceptional strength while allowing full free movement of the joint.
  • The HD-type universal joint has an induction hardened yoke for long life.
  • Lovejoy needle-bearing type joints offer high-quality, pre-lubricated, sealed needle bearings.
  • LOJ-type universal joints feature an offset pin design, making them ideal for use on hand-operated, low torque drives.
  • DD and DDX-type universal joints configuration compensate for both parallel misalignment and shaft separation.

Working Mechanism

  • Lovejoy universal joints consist of two yokes attached to either end of the shaft.
  • These yokes are joined by a central or connecting cross piece.
  • The connecting cross piece turns the bearings of the yoke with the change in angularity between shafts.
