How to test thin thrust bearings after assemble?

The thin thrust bearings is fitted with a set cage that can reliably fix and guide a large number of needle rollers,thin thrust bearings provide very high stiffness in a very small axial space.In applications where the surfaces of adjacent machine parts can be used as raceways, thin thrust bearings take up less space than traditional thrust washers
How to test thin thrust bearings after assemble?

When installing thin thrust bearings, the perpendicularity of shaft ring and shaft centerline should be checked.The method is to fix the dial meter on the end face of the case, make the contact head of the meter rotate the bearing on the raceway of the bearing shaft ring, and observe the pointer of the dial meter while the pointer is tilted, indicating that the shaft ring and the shaft centerline are not vertical.

When the hole of the shell is deep, the extended dial meter head can be used to check that the thin thrust bearings is installed correctly. The seat ring can automatically adapt to the rolling of the rolling body to ensure that the rolling is located in the raceway of the upper and lower rings.If mounted upside down, not only is the thrust bearing working abnormal, but also the mating surfaces will be seriously worn.
As the shaft ring and seat ring and the difference is not very obvious, the assembly should be extra careful. When the center of the bearing ring is deviated in operation, the clearance can ensure its automatic adjustment to avoid contact friction and make it run normally.Otherwise, severe bearing damage will be caused.
