Lubrication for rolling bearings, especially the fatigue life of rolling bearings and friction, abrasion, temperature, vibration, has important implications. Without proper lubrication, rolling bearings will not work. We have analyzed in the previous article, scrolling causes bearing damage shows that 40% per cent of the damage are associated with poor lubrication of the bearings. Therefore, good for rolling bearing lubrication to reduce friction and wear of bearings and effective measures.
　　In addition, the lubrication of rolling bearings have heat, rust-proof, sealed, ease shocks and other effects.
　　Lubrication of rolling bearings can be briefly described as follows
　　A. in two roll surfaces in contact with each other or the sliding surfaces form a thin oil film between two surfaces separated by reducing friction and wear of contact surfaces.
　　B. oil lubrication, especially with circulating oil lubrication, oil mist lubrication and oil lubrication, the lubricating oil can take most of the friction inside the bearing heat, efficient thermal dissipation role to play.
　　C. grease lubrication, prevents external dust and other foreign matter entering the bearing, played a close role.
　　D. role of lubricant to prevent corrosion of metals.
　　E. extension of fatigue life of rolling bearings.
