When inspecting and repairing the removed bearing, first record the appearance of the bearing, confirm the residual amount of lubricant, and clean the bearing after sampling. Gasoline and kerosene are commonly used as cleaning agents.

     The dismantled bearing is cleaned into rough washing and fine washing. Put a metal mesh in the container first, so that the bearing does not directly touch the dirt in the container. During rough washing, if the bearing rotates with dirt, it will damage the rolling surface of the bearing, so care should be taken. In the rough washing oil, use a brush to remove lubricants and adhesions. After it is basically clean, switch to fine washing.

     Fine washing is to wash the bearing carefully while rotating it in the washing oil. In addition, the cleaning oil should be changed frequently to keep it clean
