FAG bearing use factors mainly refer to whether the installation adjustment, use and maintenance, maintenance and repair meet the technical requirements. According to the technical requirements for bearing installation, use, maintenance, and maintenance, monitor and inspect the load, speed, working temperature, vibration, noise and lubrication conditions of the bearing in operation, find the cause immediately, and make adjustments to make it Back to normal. The installation condition is one of the primary factors in the use factor. The bearing is often caused by improper installation, which causes the stress state of the various parts of the bearing to change. The bearing runs in an abnormal state and ends its service life early. The main internal factors are Refers to the three major factors that determine the quality of the bearing, such as structural design, manufacturing process and material quality.

　　 The metallurgical quality of FAG bearing materials used to be the main factor affecting the early failure of rolling bearings. With the progress of metallurgical technology (such as vacuum degassing of bearing steel, etc.), the quality of raw materials has been improved. The proportion of raw material quality factors in bearing failure analysis has dropped significantly, but it is still one of the main factors affecting bearing failure. The proper selection of materials is still a factor that must be considered in bearing failure analysis.

　　 The manufacture of FAG 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 processes that affect the quality of the finished bearing 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.

　　 The main task of FAG bearing service life analysis is to find out the main factors causing bearing failure based on a large number of background materials, analysis data and failure modes, so as to propose improvement measures to prolong the service life of the bearing and avoid bearing outbursts.

　　 Strong metallic tone

　　 1. Abnormal load: select the appropriate assembly clearance and preload

　　 2. Poor assembly: improve the machining accuracy of the shaft and improve the installation method

　　 3. Insufficient lubricant: supplement or use suitable lubricant

　　 Regular tone

　　 1. Foreign matter causes channel corrosion, indentation, and scars: clean related parts and use clean grease

　　 2, channel spalling: fatigue wear, replace the bearing

　　 Irregular sound

　　 1. Foreign matter intrusion: clean related parts and use clean grease

　　 2. Excessive clearance: pay attention to fit and choose appropriate clearance

　　 3. Steel ball scars: the steel ball is peeled off due to fatigue or foreign matter is stuck, replace the bearing

　　 Abnormal temperature rise

　　 1. Too much lubricant: reduce lubricant

　　 2. Lubricant is insufficient or unsuitable: add lubricant or choose suitable lubricant

　　 3, the mating surface creep or the sealing device is too large: the bearing outer diameter or inner diameter mating surface is corrected, and the sealing form is changed

　 　Shaft rotation vibration is large

　　 1. Spalling: fatigue spalling, replace the bearing

　　 2. Poor assembly: improve the machining accuracy of the shaft and improve the installation method

　　 3. Foreign matter intrusion: clean related parts and use clean grease

　　 Lubricant leakage and discoloration

　　 1. Too much lubricant: reduce lubricant

　　 2. Foreign matter invasion: cleaning related parts
