Miniature bearing little knowledge

Miniature bearing little knowledge recently in mechanical knowledge class, the teacher talked about bearing the knowledge of the bearing capacity. You know what bearing in machinery parts, what is the role? Bearing is in the process of mechanical operation, fixed the other parts, reduce the weight of the friction parts. In simple terms, parts of the machine when the shaft is running, it could reduce the friction between the parts, maintaining a central location is called bearing. NMB miniature bearing are small, but it is the basis of the mechanical operation of the components and key components, no bearings, machinery and turn several times will be worn. NMB, therefore, the quality of miniature bearing, wear resistant force is very important. To produce a good bearing need many aspects of science and technology, it can be said that the quality of NBM bearing is a national machinery manufacturing strength. According to the different properties, NMB bearings can be divided into sliding bearing and rolling bearing. Rolling bearing in the development of our country has a long history, is the first country to use bearing, using history can be traced back to the qin dynasty, was used in wood car, modern bearings are used for basic metal products business. In the miniature bearing is the bearing industry, quality is also the industry leader. Due to excellent product quality, thus bearing distributors all over the world.
