The preparatory work for the normal inspection of the bearing is divided into the following 6 steps. Change the outer ring and carefully wash the junction of the cage, the rolling body and the raceway; it is necessary to completely remove the original oil trace left in any shaded part. The bearing should be cleaned after the cleaning is cleaned; Dry on a work table with clean neutral liner; or slowly dry in a far-infrared oven. Dry or dry after removing the oil; do not change the bearing ring, the holder or any of the process. Rolling elements. Rolling bearings can be removed from the oil seal package before being handed over to conventional inspections and immersed in scrub oil or acid-free fire oil with 3% oil.
2. The lubricating oil should be dripped according to the rules and immediately handed over to the bearing; the bearing that has been dried or dried. At this moment, the outer surface of the bearing is free of oil film; the whole viewing process should not be in direct contact with the skin of the human hand; the operator should wear clean gloves; or Apply rust inhibitor to the hand; however, it is necessary to prevent the rust inhibitor on the hand from mixing into the tumbling appearance of the bearing; otherwise, the measurement results will be out of error.
3. It should be handed over to the use or anti-rust stock disposal; the entire inspection process should also be completed, the bearing after the end of the inspection. Prevent the corrosion caused by the long-term rust. Focus on the use of pure gasoline without oil can also lead to corrosion.
4. Bearings that have been dried or dried; the lubricant should be dripped in accordance with the rules and immediately handed over to the inspection; at this moment, the outer surface of the bearing is free of oil film; it should not be in direct contact with the skin of the hand during the entire viewing process; the operator should wear clean gloves; Or apply rust inhibitor on the hand; however, it is necessary to prevent the rust inhibitor on the hand from mixing into the tumbling appearance of the bearing; otherwise it will cause errors in the measurement results.
5. After the bearing is finished, it should be handed over to the use or anti-rust stock disposal; the entire inspection process should also be completed, to prevent rust caused by too long. Focus on the use of pure gasoline without oil can also lead to corrosion.
6. Before the bearing is viewed, it must be placed on a metal plate in the viewing place together with the gauge block, standard parts and measuring instrument used for viewing; this can make the temperature of these objects uniform and room temperature faster.
Obviously; as long as the above preparations are strictly carried out; the ability to ensure that the results are accurate; the bearings do not rust throughout the viewing process.
