1 Check and judge
   In order to determine whether removing the INA bearings to re-use, focus on check its size accuracy, precision of rotation, internal clearance and the surface, raceway, cage, seal, and so on. On the test results, may judge by whom proficient with a bearing or are used to bearings. Determine the standards according to the mechanical properties and inspection period are different. If the following injury, INA bearings must not be reused, should be replaced.
1) Raceway surface of the strip rolling objects.
 2) Bearing parts of the fracture and defects.

2 Clean
   Check the removed bearings, first with photography and other methods to make the appearance records. In addition, confirm the remaining amount of lubricant and lubricant sampling, and then clean bearings.
1) Bearing cleaning wash coarse and fine points for washing, and placed in the bottom of the container used in the metal grid.
2) Sperm washing, the slowly rotating bearings in oil should be carefully carried out.
3) Rough wash, in the oil or grease using a brush so clear adhesive material. If the turning point in the oil bearing, note damage due to foreign bodies such as rolling surface.
Commonly used cleaning agents for the neutral water-free diesel or kerosene, is sometimes necessary to use warm lye. No matter what kind of cleaning agent used, filter should always be kept clean. After cleaning, immediately in INA bearings rust coating rust oil or grease.
