Hi I’m Mike Langley. Welcome back to Ruland’s technical video series, today I’m going to show you how to install one of our motion control disc couplings. For installation today, we’ll need a disc coupling, torque wrench, misalignment tools and your PPE. We are ready to begin.

First, make sure the shaft misalignment is within the coupling’s rating. Complete misalignment information is available on Ruland.com. Exceeding the coupling’s ratings will cause the disc coupling to fail in excessive wear and other system components such as bearings. Next, we’ll remove the disc coupling from its packaging and place it on the shafts. The shafts mate them into the relieved portion of the bore as long as it does not exceed the shaft penetration length. Please the shaft penetration is limited on certain bore sizes due to the size of the disparate. This information can be found on the product specification page along with 3D CAD drawings. Fully tighten the screw on one hub to the recommend seating torque using the appropriate torque wrench. Before we tighten the screw on the second, we need to rotate the coupling by hand to allow it to reach its free length. Began tightening the hub on the second shaft with the coupling axially relaxed and the misalignment angles centered along the length of the coupling. Fully tighten the screw to the recommended seating torque using the appropriate torque wrench. Your coupling assembly is now complete. Thank you for viewing this video.

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.
