The so-called non-oil self-lubricating means that no need to refuel or less fuel, we study the goal is to ensure that the bearings in a variety of conditions can also show good performance, and as much as possible to extend its service life. Self-lubricating bearing the basic working principle is that in the initial operation phase, the bearing surface of the solid lubricant due to the friction between the formation of transfer film and covered with the grinding parts, and ultimately the formation of solid lubricants to achieve the purpose of self- It cut off the direct contact between the workpiece, which is a good protection of the grinding parts to extend the bearing and the workpiece life.
