The importance of the P-F curve when it comes to Misalignment

September 27, 2016

The Potential to Failure Curve (or P-F Curve) gives the user information on how an asset behaves before a failure occurs. This example is focused on failure due to misalignment. The goal of a reliability focused plant is to be as far to the left on the curve as possible. While some companies are doing […]

Mistake #3 – Using a “Listen-Only” Ultrasound Instrument (Series 3 of 3)

September 20, 2016

Like any job there is a right way and a wrong way to do things. Simply listening to a bearing with an ultrasound device that gives no quantitative feedback is a recipe for disaster. The audible feedback is too subjective to draw any comparative conclusions. No two people hear the same and there is no […]

Mistake #2 – Over and Under Lubrication (Series 2 of 3)

September 13, 2016

The second mistake we should all avoid is adding too much, or not enough grease. Too much grease builds up pressure pushing the rolling elements through the fluid film and against the outer race. Increased friction and temperature dramatically shorten the bearing’s life. Not enough grease will have the same life-shortening effect. How do we […]

Mistake #1 – Lubricating based on TIME instead of CONDITION (Series 1 of 3)

September 6, 2016

Lubricating a bearing once per week or once a month may seem like a sensible thing to do. After all, performing scheduled maintenance at regular periods is an age old concept ingrained in each of us early on. Even OEMs still advise best practices based on time intervals to ensure maximum asset lifespan. The problem […]
