Synthetic lubricants are made by refining petroleum from chemical plants. Synthetic lubricating oil is mainly used for mechanical parts, especially in FAG bearings are widely used. Synthetic lubricating oil plays three roles in the application of FAG bearing components, and can also reduce the cost of equipment maintenance and management by using FAG bearings. The three roles of synthetic lubricating oil are briefly described below.

Reduce friction resistance and save production energy. The synthetic lubricating oil has remarkable wetting effect, which reduces the bearing rotation contact area and reduces friction. FAG bearing enterprises have done many experiments. Adding synthetic lubricating oil to bearings can save 3%-6% of electric energy at a certain speed ratio than adding general mineral lubricating oil or the phenomenon that does not contain lubricating oil. Especially after the synthetic lubricating oil is added to the spindle bearing of the lathe, the environmental protection and energy saving effect can significantly reach 8%-10%.

The better wettability of synthetic lubricating oil greatly reduces the damage, can prolong the disassembly period of bearing running parts, increase the service life of equipment, and improve the level of stability. In some special equipment and extreme working conditions, general lubricating oil will occur part of the exposure or performance of moldy deterioration, for example, bearing members in fast, high temperature fans must not be used ordinary lubricating oil, always cause bearing wheel lock or friction over temperature damage bearing phenomenon. In order to ensure production and manufacturing and ensure the service life of bearings, it is best to use synthetic lubricating oil.

FAG bearings continue to innovate, synthetic lubricating oil can still meet the needs of use. With the continuous development trend of machinery and equipment, bearing performance is also continuously improved. In the aerospace sector, it is necessary to achieve ultra-low temperature, continuous high temperature, long time load, high-speed rotation, ultra-high vacuum, high-energy radiation, strong oxidizing substances, long service life and other effects. For example, the selection of grease-lubricated bearings can increase the speed by 2%. Due to the efficient operation of the train, the speed ratio of the bearing of the wheel bearing of the rail train increases significantly. Lithium grease is difficult to integrate into the increased speed ratio and shaft temperature, but the synthetic lubricating oil can still meet the requirements. Synthetic lubricating oil to exceed performance, can constantly meet the needs of the development of FAG bearings.
