Cleaning of bearing: when removing the bearing, we first check the surface of the bearing, confirm the remaining amount of lubricant. After sampling the lubricant, wash the bearing with a cleaning agent or kerosene.
The cleaning of the removed bearings is divided into coarse cleaning and fine cleaning. They are placed in containers respectively. In the coarse cleaning, if the bearing is rotated with the dirt, it will damage the rolling surface of the bearing. In the coarse cleaning oil, use the brush to remove the grease and stickies. After a coarse cleaning, put it into fine washing. In addition, the cleaning oil should always be kept clean.
Bearing maintenance and judgment: in order to judge whether the disassembled bearing is workable, we need to check the raceway surface, rolling surface, mating surface condition, the wear of cage, the increase of bearing clearance, and the damage that has no size accuracy after clean the bearings.
Separate bearings like tapered roller bearings need to be checked separately for the rolling body and the raceway surface of the outer ring.
Because large bearings cannot be rotated by hand, it is important to check the appearance of rolling body, raceway surface, cage and side surface. The more importance of bearing is, the more careful inspection is required.
