Generally, the correct use of the bearing can reach the fatigue life, but there are often many reasons for premature bearing damage. Most of the causes of these damages are factors such as bearing installation, use, lubrication, or foreign matter intrusion, or insufficient understanding of the fit and temperature effects, and sometimes there are many factors at the same time.

Bearings are precision mechanical foundations. It is important that manufacturers provide high-quality products that meet standards and meet host performance, but proper use of bearings is more important. The bearing is tested and qualified, but the bearing is stuck or early failure when used. Mainly manifested in the rotation of the stuck, the working surface is severely peeled off, the cage is severely worn and even twisted and broken. A large number of failure results analysis shows that the early failure of the bearing originates from the quality problems of the bearing itself, and most of them are caused by improper installation and use.
