The nanoparticles have unique properties in lubrication and tribology such as anti-wear, reducing friction, and high load capacity. So add Nano Oxides Materials to Lithium Grease are capable of inducing the required reactions on the surfaces of bearings, thus providing reliable damage protection even under several operating conditions. A nanoparticle helps in improving the lives of the lubricating oil and consequently, the life of the bearing in machinery can save millions of dollars in emergency maintenance. The vibration analysis is the most common method used in monitoring applications; Vibration analysis of ball bearing with adding nano oxides particles like nano silicon dioxide, nano titanium dioxide and a hybrid between them to lithium grease is examined.
