What are the reasons for premature failure of imported bearings

We often encounter premature failure of imported bearings, and according to statistics, about 16% is caused by improper or incorrect installation. According to various mechanical applications, it is necessary to properly install thermal or hydraulic devices and effectively install linear bearings. Choosing the appropriate installation method for the application will help you extend the service life of the bearing, reduce the cost of premature bearing failure and potential damage caused by application. Before installation, bearings are usually heated in an oil bath. However, this method may contaminate the bearings and cause premature failure of the bearings. Today, induction heating is a commonly used heating method for bearings, due to its controllability, high efficiency, and safety. Application development standards for imported bearing induction heaters. Linear bearing induction heaters have many functions that help prevent damage to the bearings during the heating process.

In fact, if a sufficient number of bearing life tests have been conducted for each specific use to verify whether they are suitable for the selected bearings in terms of economic time and labor, the bearing life testing method is necessary or important in most cases. Before use, a standard calculation method is used to estimate the bearing life with sufficient reliability level. The metallurgical quality of imported bearing materials used to be the main factor affecting the early failure of rotating bearings. With the advancement of metallurgical skills (such as vacuum degassing of bearing steel), the quality of raw materials has been improved. The proportion of raw material quality factors in bearing failure explanations has clearly decreased, but it is still one of the main influencing factors of bearing failure. Whether the material selection is appropriate is still a factor that must be considered when explaining the failure of linear bearings.

Regarding the working conditions of the monitored bearings, there is a plan for the repair progress of the bearings in the industry, which can achieve twice the result with half the effort. Following a reasonable process, using efficient equipment and maintenance tools, and receiving professional assistance from bearing factories, all contribute to economic development. Corrosion and rust of imported bearing metals are the key points of sweat, accounting for the vast majority of metal corrosion, which is unavoidable in many cases. Hand sweat can cause corrosion of linear bearings, mainly due to sweat on the contact surface between the film and sweat. Electrochemical reactions and interactions can lead to corrosion, but it can be avoided, such as gloves and professional tools for picking up parts.

The work of lubricating grease is to separate the ball from the inner and outer raceway oil layers, use the viscosity of the oil, stick it to the ball and raceway surface, separate the inner and outer raceway from the metal interface ball, reduce the wear of the metal surface and prevent air and moisture from corroding the metal, reduce vibration and noise, and make the linear bearing rotate smoothly. The inlet bearing shows late stage fault characteristics until serious faults occur (usually bearing damage such as shaft holding, burns, sand frame cracking, raceway, bead wear, etc.), which usually take no more than one week. The larger the equipment capacity and the faster the speed, the shorter the interval time. Therefore, in the actual diagnosis of rolling bearing faults, once late stage fault characteristics are discovered, it is necessary to decisively determine the existence of faults in linear bearings and arrange maintenance as soon as possible.
