六角的

The yolk-sphere crystals possess an orthorhombic lattice and the lipovitellin molecular particles in the crystalline body are arrayed in pseudohex-agonal pattern.

卵黄球结晶体呈斜方点阵,组成结晶体的卵黄高磷蛋白分子排列呈拟六角形列阵。

With greater axial and radial load rating capacity, good replaceability of components. The shaft can be adjusted through external hexogan then to adjust the axial part dimension.

承径的承载能力都比较大，各件可替换性强。承通过心外六角来整芯位置进而达到整侧滚轮尺寸的目的。
