SAIQ thrust bearing inspection after installation

When installing SAIQ thrust bearings, check the verticality of the shaft ring and the shaft center line. The method is to fix the dial indicator on the end surface of the case, make the contact of the indicator rest on the raceway of the bearing shaft ring while rotating the SAIQ bearing, while observing the dial indicator pointer, if the indicator yaws, it means that the shaft ring and the shaft center line are not perpendicular . When the box shell hole is deep, it can also be inspected with an extended dial gauge.
　　 When the SAIQ 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 ring raceways. If it is installed backwards, not only will the SAIQ 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 obvious, you should be extra careful during assembly and make no mistake. In addition, there should be a gap of 0.2-0.5mm between the seat ring of the thrust bearing and the bearing seat hole to compensate for the errors caused by inaccurate parts processing and installation. When the center of the bearing ring shifts during operation, this gap It can be ensured that it is automatically adjusted to avoid contact and friction and make it run normally. Otherwise, it will cause severe damage to SAIQ bearings.
