The bearing seat is an important part that supports the bearing and keeps it in normal operation, and it bears the pressure and friction from the bearing and the working load. However, due to various reasons, the bearing seat may be damaged. This paper will discuss the reasons for the bearing housing damage from the aspects of material quality, improper installation, poor lubrication and working environment.

Material quality is one of the important reasons for the damage of bearing seat. If the material quality of the bearing seat is unqualified or there are defects, such as containing pores, inclusions or non-metallic inclusions, the strength and toughness of the bearing seat will be greatly reduced, which is prone to fracture or deformation. In addition, the hardness of the material will also affect the life of the bearing seat. If the material hardness is too low or too high, it will aggravate the wear and damage of the bearing seat.

Improper installation is also one of the common causes of bearing seat damage. During the installation process, if the clearance between the bearing seat and the bearing is too large or too small, it will lead to uneven bearing force, which will aggravate wear and fatigue damage. In addition, if the axial or angular position of the bearing seat is not properly adjusted during installation, it will also lead to the deflection or deviation of the bearing seat, which will cause vibration and noise, and accelerate the wear of the bearing seat.

Poor lubrication is also one of the important reasons for the damage of the bearing seat. The lubrication condition of bearing seat directly affects the life and operation performance of bearing seat. If the quality of the lubricating oil or grease of the bearing seat does not meet the requirements, or the supply of lubricating oil or grease is insufficient, the bearing seat will have poor lubrication during the working process, resulting in increased friction and increased wear of the bearing seat. In addition, if the lubricating oil or grease contains impurities or moisture, it will also accelerate the corrosion and damage of the bearing seat.

The working environment is also an important factor in the damage of the bearing seat. If the bearing seat works in a harsh environment, such as high temperature, high humidity, corrosive media and other conditions, it will accelerate the corrosion and damage of the bearing seat. In addition, if there is a large vibration and shock in the working environment, it will also have a certain impact on the normal operation of the bearing seat. Therefore, when designing and selecting the bearing seat, it is necessary to consider the characteristics of the working environment and take appropriate protective measures to extend the service life of the bearing seat.

The reasons for the damage of the bearing seat mainly include material quality, improper installation, poor lubrication and working environment. In order to ensure the normal use of the bearing seat and extend its life, it is necessary to do the corresponding work in material selection, installation adjustment, lubrication management and working environment. Only comprehensive consideration and effective control of these factors can minimize the damage of the bearing seat and improve the reliability and efficiency of the equipment.
