Thrust Bearing’s Testing After Installation

When fix the thrust bearing, squareness of ring and axis should be tested. The method is that keep the dial gauge on the surface of the end of case, make the contactor touching the bearing ring and turn the bearing, observe the dial gauge, if the needle isn’t in the middle, that shows the ring and axis in not vertical. When tha bore of case is deeper, it can be tested by lengthen dial gauge.

When the thrust bearings fix right, the seat ring can cooperate the rolling of rolling body by itself to make sure the rolling body in the roller path. If it fixed opposite, not only the bearing cannot work normally, but also the other cooperations will be attition badly. Because the seat ring and bearing ring donot have the visible distinction, so it should be careful about the installation, never make it wrong. Furthermore, it should have 0.2-0.5mm clearance between seat ring and bore, in order to redeem the error from the process and installation of elements. If the center of bearing ring is excursion during operating, this clearance can automatic adjust its distance to avoid attrition then make it operate commonly. Otherwise, it will make bearing’s damage acutly.
