What are the maintenance measures for simple failures of thin-walled deep groove ball bearings?

The reasons for the noise of thin-walled deep groove ball bearings are more complicated. One is the wear of the mating surfaces of the inner and outer rings of the bearing. Due to this kind of wear, the matching relationship between the bearing and the housing, and the bearing and the shaft is destroyed, causing the axis to deviate from the correct position, and abnormal noise occurs when the shaft is moving at high speed. When the bearing is fatigued, the metal on its surface will peel off, which will also increase the radial clearance of the thin-walled deep groove ball bearing and cause abnormal noise. In addition, insufficient bearing lubrication, formation of dry friction, and bearing breakage will cause abnormal noise. After the bearing is worn and loosened, the cage is loosened and damaged, and abnormal noise will also be produced.


When removing the thin-walled deep groove ball bearing for inspection, first make a record of the appearance with photography and other methods. In addition, confirm the amount of remaining lubricant and sample the lubricant before cleaning the bearing.

a. The cleaning of the bearing is divided into rough washing and fine washing, and a metal mesh rack can be placed at the bottom of the container in use.

b. When rough washing, use a brush in oil to remove grease or adhesions. At this time, if the thin-walled deep groove ball bearing is rotated in oil, be careful that the rolling surface may be damaged due to foreign objects.

c. When fine washing, slowly rotate the bearing in oil, and must be carried out carefully.

Commonly used cleaning agents are neutral non-water-containing diesel or kerosene, and sometimes warm lye etc. are used as needed. No matter what kind of cleaning agent is used, it must be filtered frequently to keep it clean.
