The linear guide rail is used to support and lead the moving parts. Linear guide rail, also known as slide rail, linear guide rail and linear slide rail, is used in linear back and forth vivid occasions. It has higher rated load than linear bearing, and may bear certain torque at the same time. It can realize high-precision linear movement under high load.

直線軸承重要用在主動化機械上比較多,像德國進口的機床,紙碗機,激光焊接機等等,當然直線軸承跟直線軸是配套用的.像直線導軌重要是用在精度請求比較高的機械結構上,滑塊-使活動由曲線轉變為直線 。

Linear bearings are mainly used in active machinery, such as machine tools imported from Germany, paper bowl machines, laser welding machines and so on. Of course, linear bearings and linear shafts are used together. For example, linear guide rails are mainly used in mechanical structures with high accuracy requirements, and the slider makes the movement change from curve to straight line.

高工作精度：直線導軌的活動由鋼球的轉動來實現，不僅摩擦系數降落滑動導軌的1/50，動、靜摩擦阻力曲差距亦變成很小，實現活動平穩，減少沖擊跟振動，不易產生爬行景象，故能達到um級進給定位精度，有利于進步數控體系的響應速度跟靈敏度。

High working accuracy: the linear guide's movement is realized by the rotation of the steel ball, not only the friction coefficient drops to 1 / 50 of the sliding guide, but also the dynamic and static friction resistance curve gap becomes very small, realizing smooth movement, reducing impact and vibration, not easy to produce crawling scene, so it can achieve um level feed positioning accuracy, which is conducive to improving the response speed and sensitivity of the CNC system.

大幅度降落驅動功率：因為直線導軌活動是摩擦力十分小，只有較小的能源，便能使機臺活動，明顯大幅度降落機臺電力損耗量，且因摩擦產生的熱量很小，是實用于高速，頻繁啟動跟換向的活動部件。

Driving power of large range landing: because the friction force of linear guide rail is very small, only a small amount of energy can make the machine move, significantly reduce the power consumption of the machine, and the heat generated by friction is very small. It is a kind of active part used in high speed, frequent starting and reversing.

潤滑結構簡單：直線導軌在滑塊上裝有注油孔，可直接以注油槍注入油脂，亦可連接供油管以主動供油機潤滑，使其的磨耗降更少，使機臺能長時光堅持精度。

The lubrication structure is simple: the linear guide is equipped with an oil injection hole on the sliding block, which can directly inject grease with the oil injection gun, or connect the oil supply pipe to lubricate with the active oil supply machine, so as to reduce the wear and make the machine stick to the accuracy for a long time.

防塵、密封才干強：直線導軌防生機能良好，滑塊的兩端裝有密封端蓋，底部可選用密封底片，同時滑軌固定螺釘孔配有防生螺孔蓋，避免灰塵的積聚，從而保障產品的壽命跟機能。

Dust proof and sealing ability: the linear guide rail has good anti dust performance, the two ends of the slide block are equipped with sealing end caps, and the bottom can choose sealing negative film. At the same time, the fixed screw hole of the slide rail is equipped with anti screw hole cap, so as to avoid the accumulation of dust, so as to ensure the service life and function of the product.

裝置便利、調換輕易：因為采取精巧的加工技巧，滑軌直線度高，滑軌中的裝置螺孔誤差小，裝置便利，直線導軌存在調換性，可分辨調換滑塊或滑軌，甚是直線導軌，即可使機臺從新達到高精度。

The device is convenient and easy to change: because of the exquisite processing skills, the straightness of the slide rail is high, the error of the device screw hole in the slide rail is small, the device is convenient, and the linear guide rail has the interchangeability. It can distinguish whether to change the slide or the slide rail, or even the linear guide rail, so that the machine can achieve high precision again.

承載才干大、剛度強：直線導軌采取哥德式四點接角設計，公道比值的圓弧溝槽，不僅接觸應力小，敏荷才干及剛度V型平面球點接觸時亦大大進步。因為鋼球收到對稱四點束制，可同時載受四處各方面的負荷，且多少乎無偏移景象產生，因此剛性更強更能堅持高精度。

Large bearing capacity and strong rigidity: the linear guide rail adopts the Gothic four point angle design, and the arc groove with reasonable ratio not only has small contact stress, but also greatly improves the load sensitive ability and rigidity of v-plane ball point contact. Because the steel ball received symmetrical four-point bundle system, it can carry all kinds of loads at the same time, and there is almost no offset phenomenon, so it is more rigid and can adhere to high precision.
