What are the effects of oil-free bearings in practice

My country's industry has gradually improved, and is very optimistic about it! Among them, sliding bearings and other products have undoubtedly become the focus of people's attention. Today, we can see it in many places. Experts talk about the important role of sliding bearings for us. We have a broad understanding of the importance of bearing installation. Nowadays, the requirements of imported sliding bearings, the increasingly stringent market requirements of equipment and other attributes, and their performance are also becoming increasingly diversified. In order to choose the most suitable bearing from a large number of structures and sizes, different angles are needed. However, the technology of domestically-made sliding bearings is relatively weak compared to foreign countries and needs to be further improved. Compared with sliding bearings, the internal clearance of rolling bearings is very small, and the machining accuracy of each part is higher, so the running accuracy is higher. At the same time, the rigidity of the bearing can be increased by preloading. This is very important for precision machinery. However, compared with rolling bearings and sliding bearings, each has its own advantages and disadvantages, and each has certain applicable occasions. Therefore, the two cannot completely replace each other!
