16 Things Every Vibration Analyst Hates to Hear!

October 29, 2024

Every analyst has a few things they really don’t want to hear during the course of their work. These comments often indicate that proper maintenance activities have not been performed on the equipment,  or convey unrealistic expectations of the analyst’s abilities. For instance: “It has always run like that!” “It really was making a noise […]

How to Configure a Gearbox with 3 Feet

October 22, 2024

When dealing with the alignment of a gearbox that has 3 pairs of feet, there are three possibilities when using the Easy-Laser Generation XT systems: Option 1: If the feet are located under the shaft and bearing housings, view the gearbox as a normal 4-footed machine. This will give you inboard and outboard corrections for […]

Phase in a Bearing

October 15, 2024

A vibration analyst is constantly viewing data and seeking to identify indications of sub-optimal physical properties indicated by specific vibratory behavior. Most complex systems (if vibration analysis is allowed to be called a system) can be broken down into simpler sub-systems. Some of us, this blogger included, benefit greatly from such simplification in the vibration […]

5 Symptoms of Misalignment

October 8, 2024

When we talk about industrial machinery, precision alignment plays a pivotal role in ensuring optimal performance and long life. Misalignment between rotating machines can lead to various symptoms that, if left unaddressed, can bring out significant operational issues. Whether we’re talking about pump and motor skids, turbines and compressors, or engines and generators, the impact […]

Belts Require Certain Best Practice To Ensure Reliability

October 1, 2024

Proper location is very important when collecting vibration measurements on a belt system. If possible,  one reading should be taken in line with the sheaves and one reading perpendicular to them on each bearing. Vibration data resolution should be taken into account so that proper separation between belt and driver frequencies can be obtained. Care […]

How To Have A Successful Condition Monitoring Training Experience

September 24, 2024

With training funds being difficult to obtain these days it is critical that we do everything possible to have a satisfactory and productive training experience.  This includes evaluating whether it would be more cost-effective to attend a training class off-site (such as at a vendor’s facility) or have the course conducted at your facility. There […]

Sleeve Bearing Clearance Check With a Laser

September 17, 2024

If non-repeatability is an issue and ambient vibration or mechanical looseness in the setup of the laser has been ruled out, then it may be of interest to check the bearing clearances. This can be accomplished very easily with a laser shaft alignment system. A little bit of information is necessary to accomplish this. We […]

When Moving Machines For Alignment, Always Use Jackscrews!

September 3, 2024

When moving machines for alignment,  always use jackscrews. If you don’t have them, beating on the machine frame with a steel-face hammer is a lousy idea. First, you run the risk of damaging the bearings, seals, and other delicate components in your machines. Secondly, you have little control over the magnitude of your moves. Thirdly, […]

10 Things Every Analyst Needs To Know For Good Vibration Data Collection And Analysis

August 27, 2024

Shaft speed of machine being analyzed Type of bearings involved (sleeve vs. rolling element) Rolling element bearing part number(s) and manufacturer(s) Internal configuration of equipment Machine History Proper data collection location Proper sensor to use for data collection Proper data collection setups to ensure correct data is collected Is the primary energy sub-synchronous,  synchronous or […]

Is The Training Course Right For You?

August 20, 2024

When you or your supervisor are planning attendance at a training course there is an important consideration to keep in mind. Have you met the prerequisites for the course you have selected? These prerequisites are dictated by the company presenting the course and take into account basic knowledge about the subject as well as exposure […]

7 Things to Do when Using an Induction Heater for Bearings, Sleeves, Couplings, Crane Wheels and Gears

August 6, 2024

Make sure the surfaces of the vertical posts are clean. Improve the contact between the vertical post and the crossbar by applying a light coat of Vaseline or grease to the contact surface of the vertical post. The temperature probe should always be placed on or as close as possible to the inner race or […]

What Machine Components Benefit from Precision Shaft Alignment?

July 30, 2024

With over 14 years of experience in the complex industrial world, it has become evident that certain individual parts within pumps and motors stand out in reaping the benefits of precision alignment. Let’s start with pumps, an indispensable machine in various industrial processes for moving fluid through the plant and maintaining system pressures. Achieving precision […]

Location, Location, Location! Vibration Sensor Placement

July 23, 2024

When it comes to analyzing vibration, sensor placement is key to quality of data capture.  Motors can be large, surrounded by equipment and difficult to access, so locating an area to place your vibration sensor can be harder than it looks. A poorly placed sensor can, at best, reduce the vibration getting to the sensing […]

6 Steps To Include In Your Vibration Analysis Process

July 16, 2024

Every person that performs vibration analysis develops their own analysis process.  Suggested steps at a minimum should include: 1. Open the spectrum (FFT) and locate the running speed peak and reset the reference speed to that speed.  Since all induction motors vary in speed based on the load,  this is necessary for accurate analysis, particularly at […]
