When you install the thrust bearings TIMKEN, you should verify degree of vertical shaft and shaft centerline. Approach is to dial fixed on the tank shell face, touch the top of the table at the top edge of the bearing ring raceway rotating bearings, side observation indicator pointer, pointer to swing, the shaft and shaft centerline does not vertical. Box shell holes more deeply, thousand tables can also be used to lengthen the first test.
　　Thrust TIMKEN bearings are mounted correctly, the seat can automatically adapt to the rolling of the scroll bar to ensure that rolling body Raceway is located in upper and lower circle. If you installed backwards, bearing not only does not work correctly, and all mating surfaces subjected to excessive wear. Because the shaft ring and ring and the difference is not very apparent, assembling be careful, do not make a mistake. In addition, TIMKEN bearings thrust washer and housing bore should be 0.2-0.5mm the gap between to compensate parts machining and installation errors caused by imprecise, when you offset from center of bearing rings in operation, this gap that would ensure its automatic adjustment, avoid touching the friction so that its normal functioning. Otherwise, the bearing caused by severe injuries.
