There are many kinds of linear guideways, which can be used in low speed or high speed. Due to the special design structure of the linear slide rail, it can bear the load in the upper, lower, left and right directions at the same time, unlike the sliding guide, which can only carry large load in the direction of parallel contact surface. In the use of linear guide, especially in high load, uninterrupted, reciprocating motion, it is necessary to pay attention to the timely lubrication of sliding block and slide rail. In the case of insufficient lubrication, the service life and accuracy of linear guide rail will be greatly affected.

直线导轨分为直线导轨和直线轴承。是专门为做直线往返运动而制作生产的。直线导轨较多用在自动化设备上，比如进口的机床和对精确要求高的自动焊接设备都大量采用直线导轨。直线轴承被越来越广泛的运用到电子设备、食品机械、包装机械、医疗机械、印刷机械、纺织机械、机械、仪器、机器人、工具机械、数控机床、汽车及数字化三维坐标测量设备等精密设备或特殊机械行业之中。

Linear guide is divided into linear guide and linear bearing. It is specially made for straight-line back and forth movement. Linear guideway is widely used in automation equipment, such as imported machine tools and automatic welding equipment with high precision requirements. Linear bearing is more and more widely used in electronic equipment, food machinery, packaging machinery, medical machinery, printing machinery, textile machinery, machinery, instruments, robots, tool machinery, CNC machine tools, automobiles and digital three-dimensional coordinate measuring equipment and other precision equipment or special machinery industry.

它即可适用于低速运动也可适用于高速运动，且具备高承载能力，同时由于直线导轨运动形式为滚动摩擦，移动时的摩擦力非常小，只需较小的动力便能使带负载滑块运行，尤其是在床台的工作方式为经常往返运行时，更是能明显降低能耗，提率。

It can be applied to low-speed movement and high-speed movement, and has high load-bearing capacity. At the same time, because the linear guide rail motion form is rolling friction, the friction force is very small when moving, only a small power is needed to make the sliding block with load to run, especially when the working mode of the bed table is often back and forth, it can significantly reduce energy consumption and improve efficiency.

运用直线导轨应注意以下事项：

Attention should be paid to the following matters when using linear guide rail:

1 防止锈蚀：直接用手拿取直线导轨时，要充分洗去手上的汗液，并涂以矿物油后再进行操作，在旱季和夏日特别要注意防锈。

1. Prevent corrosion: when directly taking the linear guide rail by hand, it is necessary to fully wash off the sweat on the hand, and apply high-quality mineral oil before operation. Pay special attention to rust prevention in dry season and summer.

2 装置东西要适宜：直线导轨运用适宜、精确的装置东西尽量运用专用东西，竭力防止运用布类和短纤维之类的东西。

2. The installation should be suitable: the linear guide rail should be used with appropriate and accurate devices, and special things should be used as far as possible, and the use of cloth and staple fiber should be avoided.

3 坚持环境清洗：坚持直线导轨及其周围环境的清洗即使是肉眼看不见的细小尘埃进入导轨，也会添加导轨的磨损，振荡和噪声。

Adhere to environmental cleaning: adhere to the cleaning of linear guide and its surrounding environment, even if the invisible fine dust enters the guide rail, it will also add wear, vibration and noise of the guide rail.

4 装置要认真仔细：直线导轨在运用装置时要认真仔细，不允许强力冲压，不允许用锤直接敲击导轨，不允许经过翻滚体传递压力。

4. The device should be careful: when using the linear guide rail, it is not allowed to press forcefully, not to knock the guide rail directly with a hammer, and not to transmit pressure through the rolling body.
