Through a large number of rolling bearing failure analysis shows that the bearing short or premature loss of precision, some due to material defects or improper manufacturing, but to a large extent due to not strictly in accordance with the requirements of bearing installation, maintenance, or Is the bearing improper selection or actual load exceeds the bearing load rating and other causes of abnormal bearing damage, such as bearing parts of the spalling is due in large part because of lubricating oil mixed with impurities. Visible, in order to achieve rolling bearings with longer life expectancy and accuracy of retention, in addition to requiring bearing manufacturers to improve product quality, bearing the user must also use scientific methods and procedures bearing, otherwise no matter how good the bearing will be poor Free to use under the conditions of premature death. Rolling is a precision mechanical support element, bearing the user deeply hope that the host bearing installed in the scheduled period of use will not damage and maintain its dynamic performance, but the objective fact is sometimes not satisfactory, unexpected bearing failure Will cause significant losses to users.
