Understanding Shear-Stress and the formation of bearing deposits

Varnish deposits in journal bearings pose a serious threat to the reliable operation of turbomachinery, as they can lead to increased temperatures and wear rates. Typically, varnish is predicted through oil-analysis tests, such as the MPC or UC test. However, a degradation mechanism called shear-stress can create very high temperatures, resulting in localized deposits. These deposits can occur even when most of the oil is in adequate condition and traditional varnish tests do not forecast a problem. The talk will cover this and that best way to detect shear-stress induced deposits is by monitoring bearing temperatures and vibrations.



Greg Livingstone is Chief Innovation Officer for Fluitec. He has three decades of industrial lubrication experience focused on how lubricants degrade and how to mitigate the risks associated with oil failure. He’s developed oil analysis tests, filtration technologies, solubility enhancers and other technologies used to increase the life and performance of industrial lubricants. He has volunteered in multiple industry organizations, such as STLE, ICML, and ASTM. Along his journey, he’s published almost 100 papers on these subjects and has helped hundreds of clients in over 50 countries. He recently published a book called “Turbomachinery Cholesterol: The Story of Varnish”.
