Stainless steel thrust ball bearing assembly has two key points. One is the control of the pressing quality of the cage and the steel ball, the other is the control of the nominal height T of the bearing after assembly. In addition, because the shaft ring and seat ring can be separated, there is a management problem. It is to prevent the mixed assembly of imported bearing parts. M type stamping cage uses curved edge assembly die. After pressing, the steel ball is required to rotate flexibly in the pocket, but not to fall off from the pocket, and the movement of the steel ball in the pocket shall be checked according to the technical procedures. Too deep embossing of the solid cage will make the ball movement small, and the connection between the embossing convex part and the cage is too little and the strength is insufficient, which is prone to drop blocks, causing the cage to be scrapped. The size difference between the small thrust ball bearing ring and the inner diameter of the shaft ring is very small, and there is no obvious difference between the two sleeves. In order to prevent the phenomenon of mixing, that is, a set of bearings installed into the two are found to be seat rings or shaft rings. This requires certain measures. Usually with the aid of auxiliary tooling will draw ring, seat group to be distinguished, or in the nominal height of sampling with the inside diameter gauge check the inside diameter size, in order to check the inside diameter convenient, the seat ring is placed below, the shaft ring is placed above. If the inner diameter of the seat ring has obvious quenching, heating and oxidation color or does not go through grinding, it is not necessary to check the inner diameter size, and the difference between the shaft ring and the seat ring can be clearly seen, and it is not easy to mix.

When stainless steel thrust ball bearings operate at high speed, the contact Angle between the steel ball and the radial plane of the raceway will be affected by centrifugal force.
