Pre-Alignment Checks plus Essential Clean-up and Preparation Tasks

May 22, 2014

The customer needed to align a boiler feed pump to a fluid drive. Before doing so, we took care of the simple but often-ignored pre alignment checks, including a thorough cleaning up of the area around the machines. The area was a mess to start with, and cleaning up allowed us to check for soft […]

Pre-Alignment Steps for Better Alignments in 2014

January 2, 2014

It is a good idea to complete a few pre-alignment steps prior to conducting any alignment activity.  For instance: Verify a possible misalignment condition by using a condition monitoring technology such as vibration analysis or thermography when possible.  This will help to identify the type of misalignment condition that is present, and any other conditions […]

Machine Shaft Alignment: The Virtual Move

September 10, 2013

ROTALIGN ULTRA will always suggest the ideal move, but in the real world, as we all know, that’s rarely how things work out. It may tell you to shim an impossible amount (say by asking you to remove more shims than what you have under the foot) or require a horizontal move in a direction […]

Why Align Your Rotating Equipment?

July 23, 2013

Proper equipment alignment removes many root causes of equipment failure. Some of the benefits of proper alignment are: Reducing vibration levels. Lowering vibration levels in your equipment will result in increased component life for bearings, seals, couplings and other components. For example, reducing overall vibration levels in equipment by 10% can increase bearing life by […]

Glossary of Useful Machinery Alignment Terms

January 29, 2013

Alignment – Positioning two or more machines so that the rotational centerlines of their shafts are colinear at the power of transmission point under operating conditions. Alignment specifications or targets – Desired intentional misalignment of MTBM (Machine To Be Moved) to compensate for thermal growth and/or dynamic loads. Most commonly specified as coupling target. Angularity […]

If it isn’t broken, don’t fix it

October 17, 2012

Many end users have taken laser alignment equipment and “checked” alignments on equipment that has been running satisfactorily, and very often with vibration data that falls well within alarm thresholds, only to find the alignment out of normal alignment tolerances. In this instance, the vibration data should be the determining factor. If the equipment is […]
