How To Align Shafts Using A Two-Piece Rigid Coupling

Release Date: August 30, 2019

In this video we take you through the steps to align shafts using a two-piece rigid coupling. Since rigid couplings do not allow for any misalignment they can be used to align shafts with free floating supports when properly installed.

1. Roughly align your shafts.

2. Begin assembly of your rigid coupling, just enough to feel some resistance in the screws.

3. Using a torque wrench, bring the center screws to half the recommended seating torque.

4. Using a torque wrench, bring the outer screws to half the recommended seating torque.

5. Using a torque wrench, bring all screws to the full recommended seating torque, beginning with the center screws and ending with the outer screws. Don't forget to check the coupling gap to maintain your spacing.

6. Tighten your mounts.

7. Remove your rigid coupling. Measure to confirm that your shafts are aligned.
