Bearing cleaning: when disassembling the bearing for maintenance, first record the appearance of the bearing, confirm the residual amount of lubricant, sample the lubricant used for inspection, and then wash the bearing.As a cleaning agent, the common use of cleaning agent, kerosene.Remove the bearing cleaning, coarse cleaning and fine cleaning, respectively in the container, first put on the metal net bottom, so that the bearing does not directly contact the dirt of the container.

When rough cleaning, if the bearing rotates with dirt, it will damage the rolling surface of the bearing, and attention should be paid to it.In the crude cleaning oil, use a brush to remove grease and adhesions, roughly clean, into the fine washing.Fine cleaning is to clean the bearing carefully while rotating in the cleaning oil.In addition, the cleaning oil should also be kept clean.

Bearing maintenance and judgment: in order to judge whether the removed bearing can be used, it should be inspected after the bearing is cleaned.Check the state of raceway surface, rolling surface and mating surface, wear of cage, increase of bearing clearance and damage and abnormality that have no relation to dimensional accuracy decline.Non-separated small ball bearings, the inner ring is supported horizontally with one hand, and the outer ring is rotated to confirm whether it is smooth.Separate bearing such as tapered roller bearing can check the raceway surface of rolling body and outer ring respectively.Because large bearings can not be rotated by hand, pay attention to check the appearance of rolling body, raceway surface, cage, flange surface and so on. The higher the importance of bearings, the more careful inspection should be made

As an important part of machinery, the maintenance of TIMKEN bearings can not be ignored. I hope the above methods and skills can help you.In addition, it is hot summer with high temperature and lots of rain, which is also the time when all kinds of machinery and equipment are most likely to break down.
