Analysis: The form of early bearing damage

This natural damage is unavoidable during normal use of the bearing due to wear and tear until it eventually loses its ability to work and ends its service life. However, if the bearing is prematurely worn or damaged due to improper adjustment of the engine assembly, poor quality of the lubricating oil or poor use conditions, it is an early damage caused by man.

Early damage not only greatly reduces the service life of the bearing, but also affects the normal operation of the engine. According to the long-term experience of diesel engine maintenance, the common forms of early damage of sliding bearings are mechanical damage, bearing cavitation, fatigue pitting, corrosion and so on.
