When installing a thrust bearing, the verticality of the shaft ring and the shaft centerline should be checked. The method is to fix the dial indicator on the end face of the box shell, so that the contact head of the dial is on the raceway of the bearing shaft ring while rotating the bearing, while observing the dial indicator pointer. If the pointer is deflected, it means that the shaft ring and the center line of the shaft are not perpendicular. When the hole in the box shell is deep, an extended dial indicator can also be used for inspection. When a thrust bearing is installed correctly, its seat ring can automatically adapt to the rolling of the rolling elements to ensure that the rolling elements are located in the upper and lower raceways. If installed upside down, not only will the bearing not work properly, but also the mating surfaces will be severely worn. Since the difference between the shaft ring and the seat ring is not very obvious, extra care should be taken during assembly to avoid making mistakes.
In addition, a gap of 0.2-0.5mm should be left between the thrust bearing seat ring and the bearing seat hole to compensate for errors caused by inaccurate parts processing and installation. When the center of the bearing ring deviates during operation, this gap will This ensures that it adjusts automatically to avoid contact and friction, allowing it to operate normally. Otherwise, severe damage to the bearing will occur.
