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.

直線導軌分為直線導軌和直線軸承。是專門為做直線往返運動而制作生產的。直線導軌較多用在自動化設備上，比如進口的機床和對精確要求高的自動焊接設備都大量采用直線導軌。直線軸承被越來越廣泛的運用到電子設備、食品機械、包裝機械、醫療機械、印刷機械、紡織機械、機械、儀器、機器人、工具機械、數控機床、汽車及數字化三維坐標測量設備等精密設備或特殊機械行業之中。

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.

它即可適用于低速運動也可適用于高速運動，且具備高承載能力，同時由于直線導軌運動形式為滾動摩擦，移動時的摩擦力非常小，只需較小的動力便能使帶負載滑塊運行，尤其是在床臺的工作方式為經常往返運行時，更是能明顯降低能耗，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.

運用直線導軌應注意以下事項：

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

1 防止銹蝕：直接用手拿取直線導軌時，要充分洗去手上的汗液，并涂以礦物油后再進行操作，在旱季和夏日特別要注意防銹。

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 裝置東西要適宜：直線導軌運用適宜、精確的裝置東西盡量運用專用東西，竭力防止運用布類和短纖維之類的東西。

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 堅持環境清洗：堅持直線導軌及其周圍環境的清洗即使是肉眼看不見的細小塵埃進入導軌，也會添加導軌的磨損，振蕩和噪聲。

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 裝置要認真仔細：直線導軌在運用裝置時要認真仔細，不允許強力沖壓，不允許用錘直接敲擊導軌，不允許經過翻滾體傳遞壓力。

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.
