Extend the service cycle of INA bearing maintenance and maintenance

After the INA bearing is installed, if the alignment is not carefully carried out, the alignment may cause the INA combined bearing to suffer additional load, friction and vibration. These may accelerate fatigue and reduce the service life of bearings, and may damage the service life of other machine parts. In addition, increased vibration and friction can greatly increase energy consumption and the risk of premature failure.
When the INA bearing is removed for inspection, the appearance is recorded by photography and other methods. In addition, confirm the amount of remaining lubricant and sample the lubricant, and then clean the bearing.
A. The cleaning of bearings is divided into rough washing and fine washing, and a metal mesh frame can be placed at the bottom of the container in use.
B, rough washing, in the oil with a brush to remove grease or adhesive. At this time, if the INA bearing is rotated in the oil, it will be noted that the rolling surface will be damaged due to foreign bodies.
C. When cleaning, slowly turn the bearing in oil, and it must be carried out carefully.
The cleaning agent usually used is neutral water-free diesel oil or kerosene, and sometimes warm lye is used according to the need. No matter which cleaning agent is used, always filter to keep clean.

2. Check and judge
In order to judge whether the removed INA combined bearing can be reused, it is necessary to check its dimensional accuracy, rotation accuracy, internal clearance, mating surface, raceway surface, cage and sealing ring.
3. Basic condition monitoring
During use, the basic external conditions of INA combined bearing operation should be monitored frequently, such as temperature, vibration and noise measurement, and so on. These regular inspections will identify potential problems early and will prevent unexpected machine stoppages, allowing production plans to be achieved and increasing plant productivity and efficiency.
4. Lubricate again
In the process of operation, INA bearing requires correct re-lubrication to perfect its performance. The method of bearing lubrication is divided into grease lubrication and oil lubrication. In order to make the bearing function well, first of all, it is necessary to choose the lubrication method suitable for the use conditions and purposes. If only lubrication is considered, the lubricity of oil lubrication prevails. But grease lubrication has the advantage of simplifying the structure around bearings.
5. Unload
When the bearing will reach its final life, it should be replaced. Although the bearing can no longer be used, the original INA bearing can be properly unloaded and the new bearing replaced in time, which can play a good role in promoting the extension of the service life of the new INA bearing. First, the proper discharge method and use of tools will help prevent damage to other machine components, and second, improper discharge techniques may be hazardous to the operator.
