When disassembling the bearing for inspection, first make a record of appearance using photography and other methods. In addition, confirm the amount of remaining lubricant and sample the lubricant before cleaning the bearing.
a. The bearings are cleaned by coarse washing and fine washing, and a metal grid can be placed on the bottom of the container used.
b. When rough washing, use a brush or the like in the oil to remove grease or adhesion. If you turn the bearing in oil at this time, be careful to damage the rolling surface due to foreign objects.
c. When finely washing, slowly rotate the bearing in oil, which must be carried out carefully.
Commonly used cleaning agents are neutral, non-aqueous diesel or kerosene, and warm alkaline solutions are sometimes used as needed. No matter which cleaning agent is used, it must be filtered frequently to keep it clean.
Immediately after cleaning, apply anti-rust oil or anti-rust grease on the bearing.
