The adequacy of the selection is still high precision ball bearings failure analysis of factors must be


considered. The main task of bearing failure analysis is based on a lot of background


material, analysis of data and failure modes, failure to identify the main factors causing


the bearing to make targeted improvements to extend bearing service period, to avoid the


occurrence of unexpected bearing early failure. Installation conditions is one of the


primary factors in the use of the factors bearing is often caused due to improper


installation package bearing the stress state changes between the various parts, bearing in


abnormal state operation and early failure. According to the bearing installation, use,


maintenance, maintenance of the technical requirements for operation of the bearing to


withstand load, speed, temperature, vibration, noise and lubrication condition monitoring


and inspection, abnormal immediately find reasons to adjust to return to normal.
First, along with a reasonable structure design has advanced, will have a longer Full complement cylindrical roller bearing


life. Manufacture of bearings generally through forging, heat treatment, turning, grinding


and assembly of multi-channel processing. The reasonableness of the processing technology,


advanced, will also affect the stability of the bearing life. Which affect the quality of


the finished product bearing heat treatment and grinding processes, tend to have a more


direct relationship with the failure of the bearing. In recent years, research on the


bearing surface bearing metamorphic layer show that the grinding process is closely related


to the bearing surface quality.
Metallurgical quality bearing material was the main factor affecting the early Rolling


failure. As metallurgical techniques (such as bearing steel vacuum degassing, etc.)


advances, improved quality of raw materials. Raw material quality factors in bearing


failure analysis in the proportion has decreased significantly, double row ball slewing bearing but it is still one


of the main factors bearing failure.
