VIDEO: Concepts of Shaft Alignment – Measuring Runout

The 4th video in VibrAlign’s Concepts of Shaft Alignment video series is entitled  “Runout”. The video describes what runout is and depicts how to properly measure for runout to determine if coupling eccentricity and/or a bent shaft is the source of the runout.

The video series was based on ideas for visualizing alignment created by David Zdrojewski, CEO of VibrAlign.  According to Zdrojewski, “Our research shows us that just about half of all millwrights and mechanics performing shaft alignment have never had any training.  Although VibrAlign has a staff of expert trainers who are on the road almost every week to train shaft alignment, we understand we still can’t reach all the people who need training.  That’s why we have undertaken to create a video series on the concepts of alignment.”
