called correlation dimension is an integral assembly dimension chain ring.

About Precision bearing Assembly Dimension Chain Definition
Closed loop assembly dimension chain is often imported bearing assembly precision or technical requirements. Because this requirement is met through the parts, components assembled before the final form and guaranteed, size, or position is a result of the relationship.

From the design point of view, is the lead assembly precision bearings and forming the basis for assembly dimension chain, which also determines the design and manufacture of precision parts basis. Identify with the precision of parts and the corresponding relevant dimensions, and draw the corresponding dimension chain diagram. And the accuracy of the relevant parts related parts called, the corresponding relevant dimensions, called correlation dimension is an integral assembly dimension chain ring.

The establishment of assembly dimension chain is the first step in solving the problem assembly accuracy, only when creating assembly dimension chain is correct, it makes sense to solve dimensional chain. Therefore, in the assembly dimension chain, this step is very important.Thrust bearing is installed correctly, the seat can automatically adapt to the rolling elements rolling, make sure to scroll down raceway body is located. If installed backwards, not only Backing bearings is not working properly, and each mating surface would be subjected to severe wear. As shaft ring and seat ring and the difference is not very obvious, the assembly should be careful not to mistake. In addition, the thrust bearing race with the bearing hole should be left between 0.2-0.5mm gap to compensate for parts processing, the error caused by mounting inaccuracy, when in operation bearing ring center offset, this gap would ensure its automatic adjustment, avoid touching the friction to operate normally. Otherwise, it will cause severe damage to the bearing.
