Internal factors mainly refer to the three main factors that determine the quality of WSBC imported bearings, such as structural design, manufacturing technology and material quality.
Bearing structure design and manufacturing technology factors
First of all, if the structural design is reasonable and advanced, it will have a longer life of imported WSBC bearings. The manufacture of bearings generally involves multiple processes such as forging, heat treatment, turning, grinding and assembly. The rationality, advancement and stability of each processing technology will also affect the life of WSBC imported bearings. Among them, the heat treatment and grinding processes that affect the quality of the finished WSBC imported bearings are often more directly related to the failure of the bearing. In recent years, studies on the degraded layer of the bearing working surface have shown that the grinding process of WSBC imported bearings is closely related to the surface quality.
Bearing material quality factors
The metallurgical quality of WSBC imported bearing materials used to be the main factor affecting the early failure of rolling WSBC imported bearings. With the progress of metallurgical technology (such as vacuum degassing of bearing steel, etc.), the quality of raw materials has been improved.
In the failure analysis of WSBC imported bearings, the proportion of raw material quality factors has dropped significantly, but it is still one of the main factors affecting the failure of WSBC imported bearings. In bearing failure analysis, the choice of material is still a factor that must be considered.
Measures to extend the life of imported bearings
The main task of WSBC imported bearing failure analysis is to find out the main factors causing bearing failure. Based on a large number of background materials, data and failure mode analysis, improvement measures are proposed to extend the service life of WSBC imported bearings and avoid the early failure of WSBC imported bearings suddenly. Wuxi Xinghuo Bearing Co., Ltd. provides WSBC bearing BS2-2219-2CSK.
1. For sealed WSBC imported bearings, proper grease has been filled during the production process.
2. For the bearing, a sealing device is also installed in the host to prevent grease leakage.
Can too much grease be injected into the bearing?
There is a question, how much grease should be injected into WSBC imported bearings. If the amount of grease is too small, it is easy to cause a lack of grease or dry friction, which will affect the service life. Too much grease will cause a large amount of grease to leak, pollute the environment and cause waste.
It can be seen that the amount of grease injected into WSBC imported bearings should be as small as possible under the premise of ensuring sufficient lubrication of WSBC imported bearings.
Advantages and disadvantages of grease lubrication
Under normal working conditions, most imported WSBC bearings can be lubricated with grease.
Advantages of grease
1. It is easier to keep in the WSBC imported bearing configuration, especially in applications where the vertical axis or the axis is inclined to a certain angle.
2. It has a sealing function to prevent the influence of pollutants, humidity or moisture on the WSBC imported bearings.
Disadvantages of grease
1. If there is too much grease, the operating temperature of the bearing will rise, especially in high-speed applications.
2. In most cases, only at the beginning stage, imported WSBC bearings can be completely filled with grease, while imported WSBC bearing shells can only be filled with a proper amount of grease and leave a certain amount of free space.
Before the working speed is fully reached, the excess grease must be discharged from the bearing during the running-in phase in order to retain an appropriate amount of grease in the WSBC imported bearings. When the working temperature drops significantly, it means that the grease has coincided with the bearing and is evenly distributed in the WSBC imported bearing configuration.

When the WSBC bearing is used in the field, its working load is often greater than its corresponding fatigue durability limit load.
After working for a period of time, sooner or later, it will be fatigued and peeled because its data reach the fatigue limit, and it cannot be used anymore. Even if the working load of some WSBC bearings is lower than the corresponding endurance limit load, wear failure will occur because it is difficult to eradicate the bearing contamination problem.
In short, the bearing in the field use more or less can not fully meet the conditions of the above-mentioned laboratory, and a slight lack of any of these conditions will shorten the service life of the bearing, which will lead to the life problem of the bearing.
According to the latest rolling bearing fatigue life theory, a WSBC bearing with excellent design, excellent materials, sophisticated manufacturing and correct installation, as long as it is easy to accept the load (not greater than a certain durability limit load value corresponding to the bearing), then This kind of bearing material will never cause fatigue damage.
Therefore, as long as the working environment temperature of the bearing is suitable and the range of change is small, there is no absolute solid dust, harmful gas and moisture intruding into the bearing, the bearing is smooth and appropriate, the smoothing agent is absolutely pure and free of impurities, and will not With aging, the bearing will run indefinitely.
WSBC bearings have a variety of failure modes, but most of them have no available life calculation methods. The fatigue life, wear life, smooth life and fretting life can all be quantitatively evaluated by calculation methods.
