Oil-free self-lubricating bearings means that no oil is needed. It is no need to add oil or less oil. The goal of our research is to ensure that the bearings can still show good performance under this working condition and extend their service life as much as possible. Its working principle is that in the initial operation stage, the solid lubricant on the bearing surface forms a transfer film due to the friction between each other and covers the counter-wear part, and finally forms a solid lubricant film to achieve the purpose of self-lubrication, which cuts off the workpiece The direct contact between them can protect the grinding parts and extend the service life of bearings and workpieces.
Therefore, this kind of bearing is used in many ways in our lives. It needs extra oil supply device in special environment, which can reduce the running cost of bearing, reduce equipment downtime and maintenance, and make the maintenance of machinery more convenient. Therefore, it is currently used in many fields such as light industry machinery, heavy industry machinery, construction machinery and so on, and it performs perfectly in our lives.
