直线导轨可分为：滚轮直线导轨，圆柱直线导轨，滚珠直线导轨，三种，是用来支撑和引导运动部件，按给定的方向做往复直线运动。依按摩擦性质而定，直线运动导轨可以分为滑动摩擦导轨、滚动摩擦导轨、弹性摩擦导轨、流体摩擦导轨等种类。
Linear guideways can be divided into three types: roller linear guideway, cylindrical linear guideway and ball linear guideway. They are used to support and guide moving parts to and fro in a given direction. According to the friction properties, linear motion guideways can be divided into sliding friction guideways, rolling friction guideways, elastic friction guideways, fluid friction guideways, etc.
滚珠丝杠是将回转运动转化为直线运动，或将直线运动转化为回转运动的理想的产品。滚珠丝杠是工具机械和精密机械上常使用的传动元件，其主要功能是将旋转运动转换成线性运动，或将扭矩转换成轴向反复作用力，同时兼具高精度、可逆性和效率高的特点。由于具有很小的摩擦阻力，滚珠丝杠被广泛应用于各种工业设备和精密仪器。滚珠丝杠由螺杆、螺母、钢球、预压片、反向器、防尘器组成。它的功能是将旋转运动转化成直线运动，这是螺杆的进一步延伸和发展，这项发展的重要意义就是将轴承从滑动动作变成滚动动作。
Ball screw is an ideal product to convert rotary motion into linear motion or linear motion into rotary motion. Ball screw is a transmission element commonly used in tool machinery and precision machinery. Its main function is to convert rotary motion into linear motion, or torque into axial repeated force. At the same time, it has the characteristics of high precision, reversibility and high efficiency. Due to the small friction resistance, ball screws are widely used in various industrial equipment and precision instruments. The ball screw consists of a screw, a nut, a steel ball, a prepress plate, a reverser and a dust-proof device. Its function is to convert rotary motion into linear motion, which is the further extension and development of screw. The important significance of this development is to change the bearing from sliding motion to rolling motion.
直线导轨机械行业中的领军工具，在机械式的工作中给人们带来了很大的便利，我们今天要讲的是直线导轨和滚珠丝杆大的区别是什么。
The leading tool in the linear guide machine industry has brought great convenience to people in the mechanical work. Today we want to talk about the big difference between linear guide and ball screw.
下面讲到的是直线导轨精确性如何来判断？
First of all, how to judge the accuracy of linear guide rail?
行走平行度主要是指将导轨用螺栓固定在基准面上，让滑块在导轨全长上运行的时候，滑块和导轨基准面之间的平行度误差。高度的成对相互差指的是组合在同平面上的各个滑块的高度尺寸的大值与小值之差。宽度的成对相互差指的是装在单支导轨上的每个滑块与导轨基准面之间的宽度尺寸的大值与小值之差。不同的设备可以选用不同精度的导轨。
Traveling parallelism mainly refers to the parallelism error between the sliding block and the guide rail datum plane when the guide rail is bolted to the datum plane and the sliding block runs on the full length of the guide rail. The height difference in pairs refers to the difference between the large value and the small value of the height dimensions of each slider combined on the same plane. The difference between pairs of widths refers to the difference between the large value and the small value of the width between each slider installed on a single guide rail and the guide rail datum plane. Different precision guides can be selected for different equipment.

直线导轨和滚珠丝杆区别：
Difference between linear guide and ball screw:
1.虽然同属直线传动设备，但是其工作原理、要求以及使用范围都不一样；
1. Although the same linear transmission equipment, its working principle, requirements and scope of use are different;
2.但两者的表现在直线传动方面表现却都非常出色，丝杆主要用于一些机床大型设备、雕刻机械等较为普遍，非常方便的把旋转的运动转换成直线运动，用起来非常方便，从而减少整个设备在旋转方面的磨损大大降低；
2. However, both of them are excellent in linear transmission. The screw rod is mainly used for some large machine tools and carving machines. It is very convenient to convert rotary motion into linear motion, which is very convenient to use, thus reducing the wear of the whole equipment in rotary motion;
3.直线导轨使用非常广泛但种类很多，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；也因工作条件的不同选用的直线导轨也是不同的，精密微型直线导轨LWL系列是一种超薄超轻型直线导轨。
3. Linear guideways are widely used but have many kinds. Square four row high bead guideways are used for some large machine tools, such as surface grinder, slicer, wire cutting, etc; The linear guideway selected is also different due to different working conditions. The precision miniature linear guideway LWL series is an ultra-thin and ultralight linear guideway.
适于精密测量仪器、半导体制造和检验设备、非标自动化机械设备以及其他精密直线运动为重要的应用场合等，因不同设备需要选择正确的导轨也是关重要的。
It is suitable for precision measuring instruments, semiconductor manufacturing and inspection equipment, non-standard automatic mechanical equipment and other applications where precision linear motion is very important. It is also crucial to select the correct guide rail for different equipment.
