Linear guide rail and ball screw are very different. Although they belong to linear transmission equipment, their operation principle, requirements and application scale are different, but their performance in linear transmission is very excellent. Ball screw is a transmission element often used in east-west machinery and machinery. It is composed of screw, nut, steel ball, prepress, reverser and dustproof device.

其首要功用是將旋轉運動轉換成線性運動，或將扭矩轉換成軸向重復作用力，一同兼具高精度、可逆性和高功率的特征。首要用于一些機床大型設備、雕刻機械等較為廣泛，非常便當的把旋轉的運動轉換成直線運動，用起來非常便當，然后減少整個設備在旋轉方面的磨損大大下降。

Its primary function is to convert rotary motion into linear motion or torque into axial repeated force, which has the characteristics of high precision, reversibility and high power. It is mainly used for some machine tools, large equipment, engraving machinery, etc. it is very convenient to convert the rotating motion into linear motion, which is very convenient to use, and then reduce the wear of the whole equipment in rotation, greatly reducing the wear of the whole equipment.

直線導軌運用非常廣泛但種類許多，方型四排高珠導軌用于一些大型機床設備，如平面磨床，切片機、線切割等；也因作業條件的不同選用的直線導軌也是不同的，適于測量儀器、半導體制造和查驗設備、非標自動化機械設備以及其他直線運動為重要的運用場合等，因不同設備需求選擇正確的導軌也是關重要的。

Linear guide rail is widely used, but there are many kinds. Square four row high bead guide rail is used in some large machine tools and equipment, such as plane grinder, slicer, wire cutting, etc; Due to different operating conditions, the linear guide rail selected is also different. It is suitable for measuring instruments, semiconductor manufacturing and inspection equipment, non-standard automatic mechanical equipment and other important application occasions of linear motion. It is also important to select the correct guide rail due to different equipment needs.

滾珠絲桿的特性、與滑動絲桿副比較驅動力矩為由于滾珠絲桿副的絲桿軸與絲母之間有許多滾珠在做翻滾運動，所以能得到較高的運動功率。與以前的滑動絲桿副比較驅動力矩抵達1/3以下，即抵達相同運動效果所需的動力為運用翻滾絲桿副的1/3.在省電方面很有幫忙。

The characteristics of the ball screw and the driving torque compared with the sliding screw pair are that there are many balls rolling between the screw shaft and the screw nut of the ball screw pair, so higher motion power can be obtained. Compared with the previous sliding screw pair, the driving torque reaches less than 1 / 3, that is, the power required to achieve the same motion effect is 1 / 3 of that of the rolling screw pair Very helpful in saving electricity.
