The Absolute Basics of Orbit Plots and Centerline Plots
Asset Condition Management

The Absolute Basics of Orbit Plots and Centerline Plots

Have you ever wondered where orbit plots and centerline plots come from? Have you wondered what they mean and how they provide diagnostic information about the bearing and rotor? In this highly visual presentation we will provide an introduction to the proximity probe measurements and then use a software simulator to demonstrate exactly where the orbit and centerline plot comes from. If you have any involvement with sleeve bearing machines (e.g. steam and gas turbines), then this Webinar should be a real eye-opener.

Ultrasound Finds Unexpected Lubrication Problems

While testing bearings at a major mid east cereal manufacturer high ultrasound readings were recorded on one of 7 cookers. After lubricating the bearing with the prescribed amount of grease the


Later it was discovered that the thickener had separated from the grease and clogged the cage preventing new grease from reaching the rolling elements of the bearing.

Don't just grease bearings with ultrasound, diagnose unusual problems too.

Avoid These 3 Common Mistakes When Lubricating Bearings

  1. Lubricating based on TIME instead of CONDITION
  2. Over and Under Lubrication
  3. Using a "Listen-Only" Ultrasound Instrument

Versatile Ultrasonic Diagnostic Tool “Hears” Problems Before They Lead to Breakdowns

Spectronics Corporation has introduced the MDE-2000NC Marksman™II,  an ultrasonic diagnostic tool that converts and amplifies inaudible ultrasonic sound into audible “natural” sound. This highly advanced tool allows the technician to “hear” even the smallest compressed air,  natural gas, propane tank, vacuum, steam, and other pressurized leaks…before they lead to major breakdowns.

Listen to Ultrasound to Know When to Grease

Monitoring motor bearing lubrication in a food plant with ultrasound tells us when to re-grease, and helps us avoid over greasing. It also reveals when grease has been washed down the drain.

Capturing Ultrasound Time Waveforms Pictures VS Numbers

by Jim Hall and Randy Stiver

The ability to look at the audio signal adds a wealth of information about the original ultrasonic signal and can be summarized as “pictures” versus “numbers.” The waveform reveals the instantaneous value of the signal. The wave shape reveals signal strength, transient impacts, frequency of cyclic phenomena, beats and harmonic content.

Monitoring Plain Bearings with Ultrasound

When plain bearings fail it is a sudden and often catastrophic event. Unlike roller bearings which present higher friction forces, plain bearings work under a thin microfilm of lubricant. Where

Vibration vs. Ultrasound - Two Techniques to Consider in CBM

by Jason Tranter, Allan Rienstra and Tom Murphy

If someone tells you there is only one RIGHT way to do something - you should be highly dubious! As a result of the positive reader response from "RCM vs. FMEA - There Is a Distinct Difference!" (Dec/Jan 2013), Uptime magazine has invited several subject matter experts to write short, related segments that allow our readers to consider alternatives or options when approaching maintenance reliability improvements. In this issue, we examine two popular condition-based maintenance practices and applications — Vibration and Ultrasound.
