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

metallurgical quality ntn bearing material was the main factor in the impact of early bearing failure . With metallurgical technology ( such as bearing steel vacuum degassing, etc. ) progress, raw material quality is improved. Raw material quality factors in ZYS wind turbine bearing cylindrical roller bearing failure analysis in the proportion has decreased significantly , but it is still one of the main factors bearing failure . Appropriateness of the selection is still bearing failure analysis must be considered.
The main task of bearing failure analysis is based on a lot of background material , analysis of data ZYS Precision Bearings and failure modes , identify the main factors causing ntn bearing failure , so that puts forward improvements to extend bearing service period to avoid cylindrical roller bearings sudden occurrence of early failure .
Second is probably too big a load ( preload too big ) . Speed ​​is too large. Clearance is too small . Water or other foreign matter intrusion. If the above two cases is that the shaft is not so bad precision of the bearing housing , shaft deflection great. See here, I think everyone wants to know the solution of it, first of all, to study the lubricant and lubrication method , the election of the cylindrical roller bearing lubricant , and its amount , but also to rectify ntn bearing selection . Research to tie , bearing clearance and preload , and improved sealing device . Check the accuracy of the shaft and the bearing housing .
