Why might the bearing be damaged？

1. Brute force is used during installation, and direct hammering of the bearing with a hammer will cause the greatest damage to the bearing; Is the main cause of deformation. 2. The installation is not in place, the installation is deviated or not installed to the bearing position, resulting in too small bearing clearance. The inner and outer circles are not in the same center of rotation, resulting in different centers. Suggestion: Choose appropriate or professional bearing installation tools, installation should be tested with special instruments. Two, poor lubrication (about 50%) According to the investigation, poor lubrication is one of the main reasons for premature bearing damage. The main reasons include: not filling lubricant or lubricating oil in time; Lubricants or lubricating oil is not filled in place; Improper selection of lubricant or lubricating oil; Incorrect lubrication and so on. Recommendation: Choose the correct lubricant or lubricating oil, use the correct lubrication filling method. Three, pollution (about 14%) pollution will also lead to premature bearing damage, pollution refers to dust, metal chips and other into the bearing. The main reasons include: premature opening of bearing packaging before use, resulting in pollution; Installation of the working environment is not clean, causing pollution; The working environment of bearings is not clean, and the working medium is polluted. Suggestion: It is best not to unpack the bearing before use; Keep the installation environment clean during installation and clean the bearings to be used; Strengthen the sealing device of the bearing. Four, fatigue (about 34%) fatigue damage is a common way of bearing damage. Common causes of fatigue failure may be: bearing long-term overload operation; Not timely maintenance; Improper maintenance; Equipment aging, etc. Suggestion: Choose the appropriate bearing type and replace the fatigue bearing regularly and timely. The above are the most common causes of early bearing damage; There are many reasons for the early damage of bearings, the above is the main reason to consider, and sometimes it may be a comprehensive reason. If the bearing selection is correct, the installation method is correct, the lubrication method and lubricant are correct, the bearing can work normally for a very long time.
