4 kinds of common pathogens bearing damage

A, improper installation, Accounts for about 16%) 1, use brute force, when installation directly with a hammer percussion bearing to bearing damage; Is the main cause of deformation. 2, installation does not reach the designated position, install a deviation or failure to the bearing, bearing clearance is too small. Inside and outside the circle is not in the same center of rotation, resulting in different heart. Suggestion: select the appropriate or professional bearing installation tools, installed with a special instrument to detect. Second, the poor lubrication ( Accounts for about 50%) According to the survey, poor lubrication is one of the leading causes of premature failure of the bearing. Main reasons including: failure to refill lubricant or lubricating oil; Lubricant or lubricating oil filling in place; Lubricant or improper lubricant selection; Lubrication method is not correct, and so on. Suggestion: to select the correct lubricant or lubricating oil, use the correct lubrication filling way. Third, pollution, Accounts for about 14%) Pollution can also cause premature bearing damage, pollution is refers to the dust, metal scraps into the bearing inside. Main causes include: early to open the bearing packing before use, cause pollution; When installation work environment is not clean, cause pollution; Bearing of the working environment is not clean, working medium pollution, etc. Suggestion: before use it is best not to unpack the bearing; Keep the installation environment clean, when installation to use the bearing in cleaning; Enhance the bearing sealing device. Four, fatigue, Accounts for about 34%) Fatigue damage is a common way of damaged bearing. Common fatigue failure reasons might be: bearing long-term overload operation; Not timely maintenance; Improper maintenance; Equipment aging, etc. Suggestion: select the appropriate bearing type, timely replacement of bearing fatigue on a regular basis. A: on the bearing failure under specific has two types: the basic form of an article: bearing limit speed
