Repeatability vs. Desired Outcome in Precision Shaft Alignment, Part 1

When mechanics align rotating machinery, they expect two outcomes. One, they expect their alignment values to be repeatable. Two, they expect shimming and moving machinery to produce a desired outcome-namely, to be in tolerance. In this paper, we’ll discuss repeatability, […] Read More

Using the AlignHot App (Hot Check) to Determine Thermal Growth Targets

A previous blog of mine discussed the benefit of taking a set of hot alignment readings to verify if the offset targets used for a cold alignment, to compensate for thermal growth (dynamic movement), were correct. So what if […] Read More

Useful Field Apps for Today’s Maintenance Personnel

The world of machinery maintenance continues to grow with reliability and technology at the forefront of the majority of today’s maintenance programs. The mechanics toolbox must change to support these changes. Computer based manuals and programs were the first step […] Read More

The Benefit of a “Hot” Alignment Check

There have been numerous posts on dealing with Thermal Growth and Dynamic Movement of rotating machinery. Thermal Growth continues to be a subject that is discussed and taught in our training classes, though on a daily basis is […] Read More

Don’t Overlook the Hold Down Bolt Washers

Anyone involved in precision shaft alignment knows that unintentional movement is the biggest contributor to non-repeatable alignment results. Movement can come from several sources: Soft foot, loose bolts, flexible bases, excessive bearing clearances, improperly mounted or loose sensor mounting hardware, […] Read More

Setting up OL2R (Offline To Running) and Offset (Cardan) Brackets

OL2R Measurements (Offline To Running) are used to collect very accurate (and actual) Thermal Growth Values and Targets for critical rotating machinery. Offset Measurements (Cardan Shaft) are critical for offset drives to ensure there is no angular misalignment causing lead/lag […] Read More
