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.

直线轴承重要用在主动化机械上比较多,像德国进口的机床,纸碗机,激光焊接机等等,当然直线轴承跟直线轴是配套用的.像直线导轨重要是用在精度请求比较高的机械结构上,滑块-使活动由曲线转变为直线 。

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：直线导轨的活动由钢球的转动来实现，不仅摩擦系数降落滑动导轨的1/50，动、静摩擦阻力曲差距亦变成很小，实现活动平稳，减少冲击跟振动，不易产生爬行景象，故能达到um级进给定位精度，有利于进步数控体系的响应速度跟灵敏度。

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.

大幅度降落驱动功率：因为直线导轨活动是摩擦力十分小，只有较小的能源，便能使机台活动，明显大幅度降落机台电力损耗量，且因摩擦产生的热量很小，是实用于高速，频繁启动跟换向的活动部件。

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.

润滑结构简单：直线导轨在滑块上装有注油孔，可直接以注油枪注入油脂，亦可连接供油管以主动供油机润滑，使其的磨耗降更少，使机台能长时光坚持精度。

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.

防尘、密封才干强：直线导轨防生机能良好，滑块的两端装有密封端盖，底部可选用密封底片，同时滑轨固定螺钉孔配有防生螺孔盖，避免灰尘的积聚，从而保障产品的寿命跟机能。

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.

装置便利、调换轻易：因为采取精巧的加工技巧，滑轨直线度高，滑轨中的装置螺孔误差小，装置便利，直线导轨存在调换性，可分辨调换滑块或滑轨，甚是直线导轨，即可使机台从新达到高精度。

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.

承载才干大、刚度强：直线导轨采取哥德式四点接角设计，公道比值的圆弧沟槽，不仅接触应力小，敏荷才干及刚度V型平面球点接触时亦大大进步。因为钢球收到对称四点束制，可同时载受四处各方面的负荷，且多少乎无偏移景象产生，因此刚性更强更能坚持高精度。

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.
