To the casual observer, precision shaft alignment of large machinery may look like “grunt work” a task that only requires a strong back. But those of us who perform shaft alignment know it is moving big heavy machines to within very small tolerances. As such, small movements can often make big differences in alignment quality. […]

No, it is not the place where good shaft alignments get lost – never to be seen again!  It is a way of thinking about locating machinery feet so that the shafts are in alignment, even when the feet of the moveable machine may be a few thousandths up, down, left, or right of perfect.  […]

It was an interesting math exercise so if you’re up for some brain stretching, follow along. Here are our target […]
