來自圓弧溝槽的DF(45-°45)°組合，在安裝的時候，即由鋼珠的彈性變形及接觸點的轉移，即使安裝面多少有些偏差，也能被線軌滑塊內部吸收，產生自動調心能力之效果而而得到高精度穩定的平滑運動。

The DF (45-degree 45)degree combination from the arc groove can be absorbed by the rail slider even if the installation surface is somewhat deviated from the elastic deformation of the steel ball and the transfer of the contact point during installation, which can produce the effect of automatic alignment ability and obtain high precision and stable smooth motion.

具有互換性

Interchangeability

由于對生產制造精度嚴格管控，直線導軌尺寸能維持在一定的水準內，且滑塊有保持器的設計以防止鋼珠脫落，因此部份系列精度具可互換性，客戶可依需要訂購導軌或滑塊，亦可分開儲存導軌及滑塊，以減少儲存空間。

Due to strict control of manufacturing accuracy, the dimension of linear guideway can be maintained at a certain level, and the slider has retainer design to prevent steel beads from falling off. Therefore, some series of accuracy can be interchangeable. Customers can order guideways or sliders as needed, and can store guideways and sliders separately to reduce storage space.

所有方向皆具有高剛性

High rigidity in all directions

運用四列式圓弧溝槽，配合四列鋼珠等45度之接觸角度，讓鋼珠達到理想的兩點接觸構造，能承受來自上下和左右方向的負荷；在必要時更可施加預壓以提高剛性。

Using quadrilateral arc groove and 45 degree contact angle of four rows of steel beads, the steel beads can reach the ideal two-point contact structure, which can withstand loads from the upper and lower directions and from the left and right directions. When necessary, preloading can be applied to improve rigidity.
