[0002] Deep groove ball bearing is a widely used rolling bearing, which consists of outer ring, inner ring, steel ball and cage. It can bear radial and axial loads at the same time and has the characteristics of low friction resistance, high speed, simple structure and easy use.

[0003] In order to remove residual oil, metal chips and other impurities during the processing and ensure the cleanliness and performance of the bearing, the bearing needs to be cleaned after production. Commonly used cleaning equipment includes ultrasonic bearing cleaners or high-pressure spray cleaning equipment. Ultrasonic bearing cleaners use the cavitation effect, emulsification and solubilization effect of ultrasound in the cleaning liquid to accelerate the cleaning process and improve cleanliness.

[0004] Current ultrasonic cleaning of bearings generally involves placing the bearings in a box filled with a cleaning agent. After cleaning, the bearings need to be taken out and manually removed using tools such as brushes to further remove impurities on the surface, resulting in a low overall bearing cleaning efficiency.
