Soft Foot! Or Are You Just Pulling My Leg?
It’s no joke that many machines operate with high levels of vibration due to soft foot. These same machines often have a decreased life span due to this condition.

Clean, Clean, Clean! To Eliminate Soft Foot!
There are many things that can affect the precision shaft alignment process, which needs to be checked and eliminated during the Pre-Alignment Steps, such as pipe strain, disintegrating bases, bearing or coupling wear, One of the main issues concerning shaft alignment of rotating equipment is the challenge of soft foot and its detrimental effect on the alignment process.

X, Y, Z Axis. What do they stand for?
Everything must have perspective, a point of view, to be communicated. To communicate the three spatial dimensions, we use the X,Y, Z coordinates.

The New Age of Machinery Diagnostics
Fixturlaser SMC you can achieve a second level diagnosis on any machine without help from a professional vibration analyst. It just took a tool that empowers mechanics to more quickly troubleshoot a machine at the touch of a button.

Fix the Easy Things First!
“Fix the easy things first” is an old adage, and a familiar term to some maintenance technicians. In many cases, the “easy to fix” things are where the problems are.

Is It Mils, or Thousandths, or What?
When we say, “Your laser displays in mils”, we’re asked, “What’s a mil?”

What is Misalignment Costing You?
So, what is misalignment costing you? In this case, alignments were taking up to 12 hours. 12 hours of frustration and often unsuccessful.

What is the Fixturlaser NXA Runout Probe?
Coupled with the NXA Professional, it’s a run out probe. A dial indicator. A micrometer. A documenter. And a great diagnostic troubleshooting tool!

The First Rule in Precision Shaft Alignment is “Don’t Assume”!
This is an obvious statement and most of us know what happens when we do “ASSUME” with most things in life. However, we (The VibrAlign Trainers) see assumptions being made quite often during a precision shaft alignment.
Several years ago, I read a book titled “A Millwright’s Guide to Motor/Pump Alignment” by Tommy “T-Hammer” Harlon (available through Industrial Press). Tommy’s book deals with a -
Understanding the Need for Offset Shaft Alignment!
While at facilities across the country I noticed a lack of understanding regarding the need for precision alignment of offset shaft driven rotating equipment. I myself have seen electricians and mechanics alike becoming frustrated trying to determine the cause of speed fluctuations and vibration in offset shaft driven equipment.

Pipe Strain Was the Issue
Have you ever struggled with a precision shaft alignment, even though you did everything right? (Preformed the pre-alignment steps, controlled backlash, etc., etc.) So, what was different? Maybe it was pipe strain.
