Teach you the correct method to replace bearings

The specific method for determining whether a bearing should be reported for repair, that is, the specific method for determining when a bearing has been fully utilized and is nearing failure, is as follows: 1) Use bearing working condition monitoring instruments. Using instruments such as ferrographs, SPM, or HD-1 type bearing working condition monitoring instruments to judge the working condition of the bearing and decide when the bearing should be reported for repair is the most convenient and relatively reliable method. For example, when using the HD-1 instrument, if the pointer approaches the danger zone from the warning zone and does not return after measures such as improving lubrication have been taken, it can be determined that there is an issue with the bearing itself. At this point, before entering the danger zone, the bearing can be reported for repair. The exact distance from the danger zone at which to start reporting for repair can be adjusted based on experience. Using such instruments allows for the full utilization of the bearing's potential, timely reporting of bearings for repair, and avoidance of failures, making it both safe and economical.
