Bearing if you do not select the error correctly used, before the service life of the bearing, you can use a long period of time. The other hand, there are unexpected early injury, and stand up to the early damage, as the reasons for early damage, using lubrication insufficient consideration of, and there are foreign bodies penetrated, and deflection of the shaft bearing Assembly error, inadequate study of the shaft and housing, etc. It can be said that these reasons coincide with each other more.
Metallurgical quality of bearing materials used to be the main factors affecting the early failure of rolling bearings. As metallurgy technologies (such as bearings, such as vacuum degassing of steel) progress, improvement in the quality of raw materials. Raw materials quality factors in the failure analysis of bearing the weight of has decreased significantly, but it remains one of the main factors affecting the bearing failure. Selection of propriety are still bearing failure analysis of factors that you must consider.
Main tasks of bearing failure analysis, is based on the large amount of background material, analysis of data and failure modes, identify the main factors contributing to failure so that targeted measures for improvement, and extended bearing service, avoid sudden early bearing failure.
For sealed bearings, have filled the appropriate grease during production; for bearings used in the seals were also set in the host to prevent grease leakage.
So, to fully understand the bearing using machines, used condition, bearing peripheral structures on the basis of, if you can figure out the situation before and after the accident, coupled with bearing failures and to many study visits to the cause, you can prevent the recurrence of similar incidents.
