In the rotary kiln production lines , barrel riding wheel bearings need to rely on running operation to complete , running  
sliding bearing often occur burn research and bush bearings and shaft locking , turning roofs back into bad bearing or  
shaft drawing the cover the major equipment accident . Once this incident occurred , it is necessary to stop the kiln for  
processing, time-consuming , resulting in economic losses , together with the shaft brushed replacement roller, the final cost  
will be very large . Causes of these accidents are many, such as in oil, dirty oil , oil deterioration , lubricating design and  
selection of species scraping poor and bearing , roller excessive force , are important factors discontinuity equalization .  
Lubricants and selection related course , but that is a variable factor. Was improperly selected , after use , based on the  
experience change at any suitable varieties . Dirty oil deterioration experienced people will find upon inspection , and then  
decide whether to be replaced. Just post workers starvation problem is not difficult to detect ground inspection , and  
bearing design and scraping and other factors are not easily able to find , and this problem has closely with the oil . Please
