Rolling bearings are also a kind of commonly used mechanical hardware products. They need to be lubricated continuously during use to ensure their normal work. What are the main purposes of rolling bearing lubrication? What are the methods of lubrication treatment? Today, the editor will organize the following for you, hoping to help more people have an understanding and understanding of this type of bearing!

The main purposes of rolling bearing lubrication are: 1. Reduce friction and wear: Prevent metal contact and reduce friction and wear in the mutual contact parts of the rings, rolling elements and cages that constitute the bearing. 2. Extend the fatigue life: The rolling fatigue life of the bearing will be extended when the rolling contact surface is well lubricated during rotation. Conversely, if the oil viscosity is low and the lubricating oil film thickness is not good, it will be shortened. 3. Discharge friction heat and cooling: the circulating oil supply method can use oil to discharge the heat generated by friction, or the heat from the outside, and cool it. Prevent the bearing from overheating and prevent the aging of the lubricating oil itself. 4. Others: It also has the effect of preventing foreign objects from invading the inside of the bearing, or preventing rust and corrosion. The main methods of rolling bearing lubrication: At present, there are two different methods of bearing lubrication: grease lubrication and oil lubrication; in order to make the bearing function well, first of all, it is necessary to select the lubrication method suitable for the conditions of use and the purpose of use. If only lubrication is considered, the lubricity of oil lubrication is dominant. However, grease lubrication has the advantage of simplifying the structure around the bearing. Compare the advantages and disadvantages of grease lubrication and oil lubrication.
