The DF (45- ° 45) ° combination from the circular arc groove can be absorbed by the wire rail slider even if there is some deviation on the mounting surface due to the elastic deformation of the steel ball and the transfer of the contact point during the installation of the linear guide rail, so as to produce the effect of automatic centering and obtain high-precision, stable and smooth movement.

1、具有互換性；；由于對(duì)生產(chǎn)制造精度嚴(yán)格管控，直線導(dǎo)軌尺寸能維持在一定的水準(zhǔn)內(nèi)，且滑塊有保持器的設(shè)計(jì)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(gòu)導(dǎo)軌或滑塊，亦可分開(kāi)儲(chǔ)存導(dǎo)軌及滑塊，以減少儲(chǔ)存空間。

1. Interchangeable;; Due to the strict control over the manufacturing accuracy, the size of the linear guide rail can be maintained within a certain level, and the slider is designed with a retainer to prevent the steel ball from falling off. Therefore, some series of accuracy are interchangeable. Customers can order the guide rail or slider as required, or store the guide rail and slider separately to reduce the storage space.

直線導(dǎo)軌組裝；2、所有方向皆具有高剛性

Linear guide rail assembly; 2. High rigidity in all directions

運(yùn)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(dá)到理想的兩點(diǎn)接觸構(gòu)造，能承受來(lái)自上下和左右方向的負(fù)荷；在必要時(shí)更可施加預(yù)壓以提高剛性。

The four row circular arc groove is used to match the 45 degree contact angle of the four rows of steel balls, so that the steel balls can reach the ideal two-point contact structure and can bear the load from the up and down and left and right directions; If necessary, preloading can be applied to improve rigidity.
