When installing the thrust bearing; check the straightness of the axial line of the shaft ring and the shaft. The method is to fix the dial gauge to the end face of the casing; make the contact of the watch top on the bearing shaft raceway to change the bearing; Pointer; if the pointer is yaw; clarify that the axial line and the middle line of the shaft are not straight. When the case hole is deep; it can also be checked with a long dial indicator.
When the thrust bearing device is correct; its seat can actively get used to rolling of the rolling body; ensure that the rolling body is located in the upper and lower ring raceways. If it is reversed; not only the bearing operation is not normal; and the cooperation faces will be severely worn. Because the shaft ring and The seat and the difference are not very significant; the device should be taken care of; do not make mistakes. In addition, there should be a gap of 0. 20.5 mm between the seat of the thrust bearing and the bearing housing hole; Errors in parts processing and device inaccuracies; when the bearing ring is offset in the middle during operation; this gap can ensure its active adjustment; prevent collisions; make it work normally; otherwise; it will cause severe damage to the bearing.
