First, the bearing designed with reasonable structural and advanced nature can be a longer service life.
The manufacture of bearings generally involves multiple processing procedures such as forging, heat treatment, turning, grinding and assembly. The rationality, advancement and stability of each processing technology will also affect the life of the bearing. Among them, the heat treatment and grinding process that affect the quality of finished bearings are often more directly related to the failure of the bearing. In recent years, studies on the deteriorating layer of the bearing working surface show that the grinding process is closely related to the bearing surface quality.
Second, the metallurgical quality of the bearing material is the main factor affecting the early failure of the bearing.
The quality of raw materials for manufacturing products has been significantly improved due to the progress of metallurgical technology (such as vacuum degassing of bearing steel, nitrocarburizing, etc.). The influence of the quality of raw materials in bearing failure analysis has significantly decreased, yet it is still one of the main factors in bearing failure analysis. The main task of bearing failure analysis is to find out the root cause of bearing failure based on a large number of background materials, analysis data and failure modes, so as to propose improvement measures to extend the service life of the bearing and avoid sudden bearing early failure.
Third, the bearing installation conditions are still the key factors of application.
Bearing installation conditions are one of the decisive factors in use. Some bearings are often improperly installed, resulting in changes in the stress state of various parts of the bearings, cause the bearing to operate in an abnormal state and fail early. Therefore , according to the technical requirements of bearing installation, use, maintenance and real-time monitoring and orderly inspection of the load, speed, working temperature, vibration, noise and lubrication conditions of the bearing in operation, timely discovery of abnormal conditions in time, find out the cause, and immediately rectify and restore its normal work.
