From the design point of view

About roller 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 China roller bearing 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.
