All bearings are destined to fail eventually. While ineffective lubrication practices are arguably the greatest contributing factor in such failures, the root cause(s) are rarely investigated due to production and maintenance turnaround demands. It's through...
Varnish is characterized as a deposit originating from the degradation of lubricating oils. These degradation byproducts are predominantly polar compounds, exhibiting inherent instability within the non-polar phase of the lubricating oil. Due to this chemical...
At an industrial level, bearings are, without a doubt, the most widely used assets in all sectors and allow a lot of critical and non-critical equipment to remain in service. Depending on the source consulted, the first wooden bearings that were discovered date back...
This presentation was presented at the Lubrication Reliability Virtual Summit on September 20, 2023 by Blair Fraser, with UE Systems. Discover how UE Systems cutting-edge technologies are revolutionizing maintenance practices, enhancing equipment performance and...
There are few definitive studies on rolling-element bearing reliability /life based on industry uses and working conditions. However, many claims indicate that most such bearings never achieve their engineered-life rating (some going as low as 10%). Most in the...
In Parts 1 and 2 of this series, we discussed the evolution of rolling element-bearing life calculations from the original work of Lundberg and Palmgren in the 1940s and 50s to the most recent ISO 281 standard, published in 2007. In particular, we talked about the...
In Part 1 of this series we talked about the evolution of rolling element bearing life calculations from the original work of Lundberg and Palmgren in the 1940s and 50's to the most recent ISO 281 standard, published in 2007. Central to the ISO 281:2007 standard is...
Condition-based greasing is an old and desirable idea. It is the finesse approach to fulfilling grease-based bearing care when done with precision. Efficient. Effective. Reliability-Enhancing. The most desirable objective for grease-lubricated bearings. It can be...
The Evolution of Bearing Life Calculations and the ISO 281 Standard From slow-turning pillow block bearings to high-speed fan and electric motor bearings, rolling element bearings are the most common lubricated component in any industrial plant. The earliest known...
Those who have worked in or around maintenance and reliability have probably heard about the hidden plant. This term refers to that portion of the productivity of any industry that, for some reason, is wasted and goes completely unnoticed in the eyes of the...
