Thrust bearing test after installation, the in installed thrust bearings when the first to test the verticality of the shaft washer and shaft centerline. The test method is: the dial gauge fixed in the end face of the tank shell, touch the top of the head of the table the upper rotating bearing raceways in the bearing shaft washer, then observe the dial indicator pointer, if the vertical shaft washer and shaft centerline so pointer yaw. Dial gauge pointer long tank shell hole deeper, you can also choose to be tested with the lengthening of the dial gauge head.
    The seat can automatically adapt to the rolling element rolling, rolling element is located in the upper and lower ring raceway, the thrust bearing is installed correctly. If the thrust bearing is installed backwards, if there is such a situation. The bearing is not working properly, would be subjected to severe wear and bearing mating surfaces. Shaft ring and seat the difference is not very obvious, so the assembly should take extra care. Moreover, 0.2-0.5mm gap left between the installed thrust bearing seat and bearing holes should this gap to compensate for parts processing, installation the imprecision caused the error, if there is an accident, when the operation of the bearing sleeve offset of the center of the ring, this gap can generate a significant role, to ensure its automatic adjustment of to avoid touching friction, bearing normal operation. Without this gap will cause intense damage of the bearing. Resulting in bearing damage can not be used.
