1. Bearings generally use kerosene or gasoline as cleaning fluid.
2. Separate the washing tank into rough washing and fine washing, and put a metal mesh on the bottom of the tank to prevent the bearing from directly contacting the dirt in the washing tank.
3. In the rough washing tank, try to avoid rotating the bearing, use a brush to roughly remove the dirt attached to the bearing surface, and then put it in the fine washing tank.
4. In the fine washing tank, gently move the bearing to clean it. The cleaning oil in the fine washing tank must always be kept clean.
5. After cleaning, degrease, if it is grease lubrication, perform the process of filling grease. If it is oil-air lubrication, try to install it on the main shaft without the bearing rotating. (At this time, apply a thin layer of lubricating oil on the surface and inside of the bearing, the effect is better.)
