How Bearing Defects Show Up

July 17, 2018

This blog post concerns rolling element bearings and not journal bearings. When a rolling element bearing begins to deteriorate the damage usually manifests itself in one of the races (either inner or outer) followed by the rolling element, and finally the cage.  When the races begin to have defects these tend to excite the natural […]

When is it Okay to Over-Lubricate your Bearing?

July 10, 2018

Question: When is it OK to over-lubricate your bearing? Answer: NEVER!!!!, (almost) the exception is when high vibration exists. If you attended the SDT/LUDECA Acoustic Lubrication Workshops then you now understand grease as a lubricating mechanism. You understand that the Churning Phase of the lubrication task is inevitable, and long-term, detrimental to the health of […]

A Difficult Alignment Made Easy

June 28, 2018

Guest Post by Bob Dunn from I&E Central, Inc. I had the opportunity use the Easy-Laser XT440 to assist a customer aligning a machine that had perpetually given them problems, with bearings always running hot. They had recently aligned the machine with dial indicators, but when we checked, it was off by .007, and this on […]

Are you Listening to the Heartbeat of your Equipment?

June 28, 2018

In most cases, when equipment is in failure mode, it begins to make sounds that are not commonly heard during normal operation conditions. Once this sound is heard a defect (at least one) is already present in the equipment. Using our vibration tools can assist in detecting the defect before that sound is heard with […]

3 Practical Tips for Ultrasound Leak Detection

June 28, 2018

There are 3 techniques that can facilitate your work in the field: the shielding technique, the covering technique and reflection management. 1. Shielding technique This technique greatly reduces the influence of interfering leaks. It consists in using a piece of cardboard or foam(*)… to create a barrier between the “parasitic” leak noise and the location […]

Three Things That Kill Your Reliability And What You Can Do About Them Now

June 28, 2018

As Published by Solutions Magazine March/April 2018 issue by Ana Maria Delgado, CRL and Shon Isenhour, CMRP CAMA CCMP, Founding Partner at Eruditio LLC During the many root cause analysis (RCA) investigations we facilitate and coach, we notice some themes that continue to manifest themselves in the findings. Often, they are grouped under the heading […]

Machine Life Expectancy – What Should the Maintenance Organization Focus on?

May 29, 2018

Guest post by John Lambert at Benchmark PDM Recently I have been seeing the P to F interval curve popping up a lot on my LinkedIn feed and in articles that I have read. It was a concept that I was first introduced to when I was implementing Reliability Centered Maintenance into the Engineering and Maintenance […]

6 Signs your Lubrication Program is on Track

May 22, 2018

1. A Change in the Quantity of Grease Consumed Maintenance departments track their grease consumption to monitor and control costs. A change in consumption is a sure sign that your lubrication program is on the right track. Most organizations are guilty of over-lubricating. Expect lower grease consumption as your program matures. Bad procedures lead to […]

How Long Does it Take to do a Machinery Alignment ?

May 15, 2018

In the 35+ years of experience that LUDECA has in shaft alignment, we have been asked this question many times. How long does it take to do an alignment? People in charge of scheduling have a tough task when allotting time for technicians to do an alignment with precision. In many cases they may just […]

What it Takes to be Successful at Balancing

May 8, 2018

Just what does it take to be successful at balancing?  Let’s start with some basics. First you need to have an understanding of the balancing process, next nomenclature: is it unbalance, imbalance, out of balance, or what? Use a consistent description and stick with it. Next, think about what the source of unbalance could be: […]

Where Should I Place My Ultrasound Sensor on a Gearbox?

May 1, 2018

A proven method to assess gearbox condition is to collect a DYNAMIC ultrasound signal. If possible, you want to capture at least 3-5 revolutions of the gearbox. From there, analysis is straightforward. Use Ultranalysis (UAS2) software to view the signal in the time waveform and spectrum displays. Use the software’s many analysis tools to determine […]

Is Your Vibration Analysis Pointed in the Right Direction?

April 10, 2018

With the proliferation of online monitoring systems utilizing permanently mounted sensors, users will need to beware of “direction sensitive” vibration and possible sudden unexpected failure due to insufficient data. The thought of insufficient data may seem incredible when thinking of constantly monitored equipment, but consider the all too common (imho) practice of uni-directional (one direction) […]

All About Arc-Seconds

April 3, 2018

An arc-second is a measurement unit for angle. It is often used in describing level and plumb. 1 arc second = 1/3600 degree = 0.000278 degree =0.0000048 inches/inch =0.0048 mils/inch = 0.0048 mm/m 1 degree = 17.347 mils/inch 1 mil/inch = 1 thou/inch = 1 mm/m (The metric-imperial relationship is purely a coincidence!) A high […]

Don’t Let your Equipment/Machinery Get a High

March 27, 2018

While the person in charge of collecting vibration data is actually collecting the data, they should watch the data “live” for unusually high amplitudes or discontinuities in the data. This will not increase the data collection time, and if any of these issues are detected, the person can evaluate whether or not the data is […]

Is a “Mil” or “Thou” The Same Measurement?

March 20, 2018

“Mil” and “thou” are the same. They are imperial measurements both are synonyms for 0.001 inches.  This unit is normally referred to as a “thou” (which is short for a thousandth), or (particularly in the United States) a mil. Mil has its origins from metric prefix “milli”, which is Latin for “one thousandths”.  Plural of […]

Create a Compressed Air Leak Management Program

March 13, 2018

Why We Ignore Leaks Compressed air is a misunderstood utility. As such, it tends to be misused and even abused. Leaks continue to be the biggest problem; often overlooked because they are difficult to detect, don’t smell bad, don’t make a mess on the floor, and rarely stop production. The Real Cost of Leaks One […]
