1, cleaning
When the SKF bearing is removed and inspected, the appearance record is first recorded by photography. In addition, confirm the amount of lubricant remaining and sample the lubricant before cleaning the SKF
bearing.
a. The cleaning of the SKF bearing is carried out by rough washing and fine washing, and a metal mesh frame can be placed on the bottom of the used container.
b. When rough washing, remove the grease or adhesive with a brush or the like in the oil. At this time, if the SKF bearing is rotated in the oil, be careful that the rolling surface will be damaged by foreign matter or the like.
c. When fine washing, slowly rotate the SKF bearing in the oil, and it must be carried out carefully.
The cleaning agent generally used is a neutral non-aqueous diesel oil or kerosene, and a warm alkali liquid or the like is sometimes used as needed. Regardless of which cleaning agent is used, it is often filtered and kept clean. Immediately after cleaning, apply anti-rust oil or anti-rust grease to SKF bearings.
2, inspection and judgment
In order to judge whether the removed SKF
bearing can be reused, it is important to check its dimensional accuracy, rotation accuracy, internal clearance, mating surface, raceway surface, cage and seal.
Regarding the inspection results, it can be judged by the SKF bearing or the SKF bearing.
The criteria for judgment vary depending on mechanical properties and importance, inspection period, and the like. SKF bearings must not be reused if they are damaged and must be replaced.
1) Breakage and defects of SKF bearing components.
2) Peeling of the rolling surface of the raceway surface.
