The cause of the imported bearing damage - bearing knowledge

A, improper installation, Accounts for about 16%) 1, use brute force, when installation directly with a hammer percussion bearing on imported bearing damage; Is the main cause of deformation. 2, installation does not reach the designated position, install a deviation or failure to import bearings, imported bearing clearance is too small. Inside and outside the circle is not in uniform rotation central, resulting in different heart. Suggestion: select the appropriate or professional import bearing installation tools, installed with a special instrument to detect. Second, the poor lubrication ( Accounts for about 36%) According to the survey, poor lubrication is one of imported bearings of the main causes of premature failure. Main reasons including: failure to refill lubricant or lubricating oil; Lubricant or lubricating oil filling in place; Lubricant or improper lubricant selection; Lubrication is not accurate and so on. Advice: choose accurate lubricant or lubricating oil, the use of accurate way of lubrication filling. Third, pollution, Accounts for about 14%) Pollution can also cause pollution of the imported bearing premature failure, refers to dust, metal scraps into import bearings inside. Main causes include: use before early to open the packaging imported bearing, cause pollution; When installation work environment is not clean, cause pollution; Imported bearing working environment is not clean, working medium pollution, etc. Suggestion: before use it is best not to unpack the imported bearing; Keep the installation environment clean, when installation to use imported bearings for cleaning; Increase imports bearing sealing device. Four, fatigue, Accounts for about 34%) Fatigue damage is a common way of damage import bearings. Common causes of fatigue damage might be: import bearing long-term overload operation; Not timely maintenance; Improper maintenance; Equipment aging, etc. Suggestion: select the appropriate import bearing type, timely replacement tired imported bearing on schedule. The above is the most common kinds of cause the cause of early damage of the imported bearing; Cause the cause of early damage of the imported bearings are various, the above is a main consideration reason, sometimes may be integrated. If import bearing selection, accurate installation in place accurately, lubrication and lubricants accurate choice, imported bearings can be normal work time very often.
