How to properly install the thrust bearing

    The thrust bearing is to be inspected after installation. When installing the thrust bearing, first check the verticality of the shaft ring and the centerline of the shaft. The test method is: fix the dial gauge on the end surface of the casing, so that the contact of the watch top rotates the bearing on the bearing shaft raceway, and then observe the dial gauge pointer. If the shaft ring and the shaft center line are not perpendicular, then the pointer Hemiplegia. The pointer of the dial gauge has a relatively long length. If the box hole is deep, you can also choose to use the extended dial gauge for inspection.

    The seat ring can automatically adapt to the rolling of the rolling elements, ensuring that the rolling elements are located in the upper and lower ring raceways, indicating that the thrust bearings are installed correctly. If the thrust bearing is reversed, if this happens. The bearings are not working properly and the mating surfaces of the bearings are subject to severe wear. The difference between the shaft ring and the seat ring is not very obvious, so care should be taken in the assembly. Moreover, there should be a gap of 0.2-0.5mm between the seat ring of the thrust bearing and the bearing seat hole. This gap is used to compensate for the error caused by inaccurate machining and installation. If there is an accident, the bearing sleeve is in operation. When the center of the circle is offset, this gap can make a big difference, ensuring that it automatically adjusts to avoid contact friction and keep the bearing running normally. If there is no such gap, it will cause severe damage to the bearing. The bearing is damaged and cannot be used.
