来自圆弧沟槽的DF(45-°45)°组合，在安装的时候，即由钢珠的弹性变形及接触点的转移，即使安装面多少有些偏差，也能被线轨滑块内部吸收，产生自动调心能力之效果而而得到高精度稳定的平滑运动。

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.

具有互换性

Interchangeability

由于对生产制造精度严格管控，直线导轨尺寸能维持在一定的水准内，且滑块有保持器的设计以防止钢珠脱落，因此部份系列精度具可互换性，客户可依需要订购导轨或滑块，亦可分开储存导轨及滑块，以减少储存空间。

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.

所有方向皆具有高刚性

High rigidity in all directions

运用四列式圆弧沟槽，配合四列钢珠等45度之接触角度，让钢珠达到理想的两点接触构造，能承受来自上下和左右方向的负荷；在必要时更可施加预压以提高刚性。

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.
