Installation Instructions

  1. Assure that the misalignment between shafts is within the coupling's ratings.
  2. Align both hubs of the coupling on the shafts that are to be joined.
  3. Fully tighten the screw(s) on one hub to their recommended seating torque.
  4. Before tightening the screw(s) on the second hub, rotate the coupling by hand to allow it to reach its free length.
  5. Tighten the hub on the second shaft such that the misalignment angle remains centered along the length of the coupling and the coupling remains axially relaxed.
