Years ago, an automotive oil filter company’s ad campaign, capitalized on the phrase “pay me now, or pay me later”. The premise was that you could pay less upfront for an inferior oil filter, and then pay again because the oil filter would fail, and your vehicle’s engine would require an overhaul. Or, you could […]

| |

By on February 5, 2020

The validity rule is an important concept in precision shaft alignment. It can be used to confirm that your readings are accurate and is why we don’t have to rotate a full 360 degrees in order to get accurate alignment information. Here is a previous blog post with an embedded video that discusses dial indicator […]

This Could Be Difficult!

By on November 6, 2019

For the field portion of a recent training class, the decision was made to check the alignment on a plastic extruder. At first glance, checking the alignment of the motor shaft to gearbox input shaft is pretty straightforward. However, the output side of the gearbox had two shafts, so maybe this is not so straightforward. […]

During a recent training class at the facility of a client who had their initial Shaft Alignment Best Practices training class 5 years prior, I found out none of the previous class attendees were still in maintenance.

By on April 9, 2019

Over the past few years I have had training classes for the maintenance personnel at several ski resorts in the Rocky Mountains. These are some of the most memorable training trips I have had.  But apart from the beauty of these areas, there is one downside for some: the high altitude.  These resorts are typically […]

Visual Inspection of Couplings and Machinery Components

| | |

By on March 27, 2019

Some things just don’t pass the “eye test”.  Your eyes are actually great tools for seeing things that are not straight, not plumb, not level (pictures hanging on a wall for example), not right.  Many times, just by looking at a coupling you can tell “it’s not aligned”, and you are usually correct. Visual Inspection: […]

STILL FRUSTRATED!!!

By on March 21, 2019

Although we have many excellent blogs on the cause of non-repeatability, or more commonly known as frustration when attempting a precision shaft alignment, this issue continues to come up nearly every training session I conduct. And the number one cause? Not controlling backlash or looseness. All the trainers teach this and VibrAlign has a very […]

Alignment Check vs. Alignment

| | | |

By on March 7, 2019

One question that arises regularly in training is about doing alignment checks. Is it okay to just check the alignment? Of course, it is. As a matter of fact, many industries have dedicated crews to specifically do alignment checks. The major difference is no equipment is moved, just measured. We lockout, remove guards, install the […]

How Do You Align Machinery on a Flexible Base?

By on November 20, 2018

This is as much a title for a blog as it is a question. One our Technical Trainers once stated that to align rotating machinery, they must first be alignable. What is meant in part by this is that when we have a collinear tolerance of 0.5mil /1” angularity and 2.0 mils offset, the machines […]
