Machine tool bearing classification

Machine tool bearings are classified according to their structure and use. According to the structure can be divided into rolling bearings and plain bearings, rolling bearings can be subdivided into spherical contact, cylindrical roller, cone roller and other types; The plain bearing includes liquid lubrication and solid lubrication. According to the purpose of classification, there are different types of main load support bearings, auxiliary support bearings and positioning guide bearings. These classifications have important guiding significance for the selection of suitable machine tool bearings, which can ensure the stable operation of the machine tool and high precision.

Machine tool bearing application

Machine tool bearings are widely used, involving various types of machine tools, such as lathes, milling machines, drilling machines, etc. In the machining process of the machine tool, the bearing plays an important role in supporting and rotating, which can ensure the stable operation of the machine tool and high precision. Different types of machine tools need to use different kinds of bearings to meet their specific work needs. Therefore, when manufacturing and maintaining mechanical equipment, it is crucial to select the right bearings and apply them correctly.

The difference between needle bearings and roller bearings

The difference between needle roller bearings and roller bearings is that they use different rolling body shapes. Needle roller bearings use cylindrical needle roller as the rolling body, and roller bearings use cylindrical or conical rollers as the rolling body. Because of the different shape of the rolling element used by the two, they have certain differences in load capacity, speed limit, friction coefficient and so on. In addition, there are also some differences in installation and maintenance, which need to be selected and applied according to the specific situation.

Application of angular contact bearings

Angular contact bearing is a common mechanical component, widely used in industrial production. It is mainly used to support and rotate the load on the shaft, which can effectively reduce friction and wear and improve the operation efficiency of the equipment. Angular contact bearings can be seen in a variety of mechanical equipment, such as automotive engines, wind turbines, aerospace equipment and other fields. Because of its reasonable structural design, strong wear resistance, long service life and other advantages, it has been widely favored and has become an indispensable part of modern industrial production.

Bearing quality inspection

This standard was formulated early. The quality level of bearings is determined by measuring the vibration acceleration value when the bearings are rotating. It is divided into three quality levels: Z1, Z2 and Z3 from low to high. At present, domestic bearing manufacturers are still using the vibration acceleration value to measure the quality of bearings, which simply reflects the fatigue life of bearings.

Bearing Introduction

China is one of the countries that invented rolling bearings earlier in the world. In Chinese ancient books, the structure of axle bearings has long been recorded. According to the archaeological relics and materials, the oldest bearing in China with the embryonic form of modern rolling bearing structure appeared in Xuejiaya Village, Yongji County, Shanxi Province, in 221~207 BC (Qin Dynasty).
