[0002] TAROL bearings are often used in rail vehicles such as buses and trucks. They are easy and quick to install. However, the cleanliness or impurities in the bearings have a huge impact on the accuracy, noise and life of the bearings, and sometimes even a fatal impact. Therefore, the cleanliness of the bearings must be controlled during installation and use.

[0003] The existing TAROL bearing cleaning device disassembles all the components including the outer ring, inner assembly and middle spacer ring of the bearing and lays them flat on a metal net, and uses high-pressure water flow to clean them from top to bottom. During the cleaning process, all components are in a relatively static state. The bearings under inspection are all used bearings. There is waste grease in the gap between the bearing roller and the cage, and there is waste grease on the contact surface between the bearing roller and the inner ring raceway. The waste grease in other gaps is not easy to clean, which affects the overall cleaning effect of the bearing. In addition, the bearing needs to be disassembled each time, which has low cleaning efficiency and high labor costs. Utility Model Content
