Bearing cleaning: When disassembling the lower bearing for inspection, first record the appearance of the bearing, confirm the residual amount of lubricant, and after sampling the lubricant for inspection, wash the bearing. As a cleaning agent, gasoline and kerosene are commonly used.
The cleaning of the removed bearings is divided into coarse cleaning and fine cleaning. They are placed in the container respectively, and the metal mesh bottom is placed first so that the bearing does not directly contact the container. When rough cleaning, if the bearing is rotated with dirt, it will damage the rolling surface of the bearing and should be noted. In the rough cleaning oil, use a brush to remove the grease and the adhesive. After it is almost clean, it is transferred to the fine wash.
Fine washing is to carefully clean the bearing while rotating it in the cleaning oil. In addition, the cleaning oil should always be kept clean.
Bearing inspection and judgment: In order to judge whether the removed bearing can be used, it should be checked after the bearing is cleaned. Check the condition of the raceway surface, the rolling surface, the mating surface, the wear of the cage, the increase of the bearing clearance, and the damage and abnormality with irrelevant dimensional accuracy. For non-separable miniature ball bearings, use one hand to support the inner ring and horizontally rotate the outer ring to check if it is smooth.
Separate bearings such as tapered roller bearings can be inspected separately for the rolling surfaces of the rolling elements and the outer ring.
Large bearings cannot be rotated by hand. Pay attention to the appearance of rolling elements, raceways, cages, ribs, etc. The higher the importance of bearings, the more careful inspection is required.
