What are the cleaning methods for bearings?


  1. Cleaning of the roller bearing: When disassembling the lower bearing for inspection, first record the appearance of the bearing, confirm the residual amount of the lubricant, and wash the bearing after sampling the lubricant for inspection. As a cleaning agent, gasoline and kerosene are commonly used.

  2. tapered roller bearings and other separate bearings, the rolling element, the outer ring of the raceway surface can be separately checked the cleaning of the roller bearing bearings, divided into coarse cleaning and fine cleaning, respectively placed in the container, first placed The metal mesh bottom allows the bearing to not directly contact the container's dirt.

  3. 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 rotate the bearing while rotating it in the cleaning oil.

  4. large roller bearings pay attention to check the appearance of rolling elements, raceway surface, cage, ribs, etc., the importance of the bearing is higher, the need to carefully check. After washing, 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 that is irrelevant to the dimensional accuracy. For non-separable miniature ball bearings, use one hand to support the inner ring horizontally and rotate the outer ring to check if it is smooth.
