It is well known that the sales volume, quality and quality of SEMRI bearings are the highest in the world, and have a professional production line, which can be used in the world. Bearing quality is the most important basis for the recognition of the market, then from what aspects to determine the quality of the ball bearing?

Internal factors mainly refers to the structure design, manufacturing process and material quality and other factors to determine the quality of the three major factors.

The metallurgical quality of bearing material was the main factor that affected the early failure of rolling bearing. Along with the progress of Metallurgical Technology (such as vacuum degassing of bearing steel, etc.), the quality of raw materials is improved. The proportion of raw material quality factor in the failure analysis of SEMRI bearing has obviously decreased, but it is still one of the main factors affecting the failure of thrust ball bearing. Whether the selection of material is still a factor that must be considered in the bearing failure analysis.

General bearing manufacturing process of forging, heat treatment, turning, grinding and assembly, etc.. The rationality of the processing technology, advanced nature, stability will also affect the bearing life. Which affect the quality of the finished products of heat treatment and grinding process, often with the bearing failure has a more direct relationship. In recent years, the research on the surface modification of the bearing has showed that the relationship between the grinding process and the surface quality of bearing is closely related.

The main task of the service life analysis of thrust ball bearing is to find out the main factors causing the failure of the bearing according to a large amount of background material, analysis data and failure mode, so as to improve the measures to prolong the service life of SEMRI bearing and avoid the early failure of bearing.

First, the bearing of the industrial design and reasonable improvement with the world class level, strong quality assurance of its service life. Bearing forging have to undergo a rigorous forging, bearing heat treatment, turning, grinding and bearing equipment, such as a rigorous process, a variety of machining processes will affect the service life of the bearing. Which affect the quality of finished products, are directly related to the failure of the bearing. With the development of the technology, the surface of the bearing surface is found to be closely related to the quality of the surface of the fish bearing.

Second, metal material used in thrust ball bearing manufacturing, which is a major factor affecting the failure of SEMRI bearing, and now with the continuous progress of metallurgical technology, raw material extraction has been a very good improvement, the quality of material has been greatly improved, and now the quality of raw materials in the bearing failure has been significantly reduced, at this stage, the problem is still there.

Third, bearing manufacturing material selection is not qualified is also bearing failure of a factor, in the detection of normal bearing failure is mainly based on a large number of materials, data analysis, failure environment, forging process, to find out the main factors of bearing failure, and to solve the continuous optimization of bearing, service life, and efficiency improvement. To prolong the service life of bearing and avoid the early failure of bearing. Installation condition is one of the most important factors in the use of factors, the bearing is often due to improper installation of the whole bearing parts between the force state change, bearing in abnormal state operation and early failure. According to the technical requirements for the installation, maintenance, and maintenance of the thrust ball bearing, the SEMRI bearing can monitor and inspect the load, rotate speed, operating temperature, vibration, noise and lubrication condition.
