How to maintain and maintain bearings
1. In order to fully utilize and maintain the expected performance of bearings for a long time, it is necessary to effectively carry out regular maintenance (regular inspections). It is important to detect faults early and prevent accidents from happening before they occur through appropriate regular inspections, in order to improve productivity and economy.
2. When cleaning and disassembling the bearings for inspection, first use photography and other methods to make appearance records. In addition, it is necessary to confirm the amount of remaining lubricant and sample the lubricant before cleaning the bearings.
3. The cleaning of bearings can be divided into rough cleaning and fine cleaning, and a metal mesh frame can be placed at the bottom of the container used.
4. During rough cleaning, use a brush or other tool to remove lubricating grease or adhesive in the oil. If the bearing is rotated in oil at this time, be careful not to damage the rolling surface due to foreign objects and other factors.
5. During fine cleaning, slowly rotate the bearing in oil and carefully perform it.
6. The commonly used cleaning agents are neutral non aqueous diesel or kerosene, and sometimes warm alkaline solution is also used as needed. Regardless of the type of cleaning agent used, it is important to filter regularly to maintain cleanliness.
7. After cleaning, immediately apply anti rust oil or grease to the bearings.
8. In order to determine whether the removed bearings can be reused, it is important to focus on checking their dimensional accuracy, rotational accuracy, internal clearance, mating surfaces, raceway surfaces, retainers, and sealing rings.
9. The inspection results can be judged by those who are accustomed to using bearings or proficient in bearings.
10. The criteria for judgment vary depending on mechanical performance, importance, and inspection cycle. If the following damages occur, the bearing must not be reused and must be replaced.
