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

Shims 201 – The Importance of Measuring Shim Thickness

Stainless steel shims are now the standard for use in shimming machinery when preforming a precision laser or dial indicator shaft alignment.  They are clean, corrosion resistant, flat, and most importantly, pre-cut.  Their use speeds up the alignment process significantly.  […] Read More

Aligning Uncoupled Machines

Normally, it is faster and more accurate to perform shaft alignment while the machines are coupled together.  This offers several benefits such as:  Keeping the relative angular positions of the shafts the same allows the technician to align the true […] Read More

Shims 101

Stainless steel shims have for the most part replaced cutting shims from rolled stock. They speed up the alignment process dramatically. They usually assure a more accurate alignment since they come in many different thicknesses. They are clean, flat, and […] Read More
