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.

其首要功用是将旋转运动转换成线性运动，或将扭矩转换成轴向重复作用力，一同兼具高精度、可逆性和高功率的特征。首要用于一些机床大型设备、雕刻机械等较为广泛，非常便当的把旋转的运动转换成直线运动，用起来非常便当，然后减少整个设备在旋转方面的磨损大大下降。

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.

直线导轨运用非常广泛但种类许多，方型四排高珠导轨用于一些大型机床设备，如平面磨床，切片机、线切割等；也因作业条件的不同选用的直线导轨也是不同的，适于测量仪器、半导体制造和查验设备、非标自动化机械设备以及其他直线运动为重要的运用场合等，因不同设备需求选择正确的导轨也是关重要的。

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.

滚珠丝杆的特性、与滑动丝杆副比较驱动力矩为由于滚珠丝杆副的丝杆轴与丝母之间有许多滚珠在做翻滚运动，所以能得到较高的运动功率。与以前的滑动丝杆副比较驱动力矩抵达1/3以下，即抵达相同运动效果所需的动力为运用翻滚丝杆副的1/3.在省电方面很有帮忙。

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.
