1. High positioning accuracy when using the linear guide rail as the linear guide, because the friction mode of the linear guide rail is rolling friction, not only the friction coefficient is reduced to 1 / 50 of the sliding guide, but also the gap between dynamic friction and static friction becomes very small. Therefore, when the bed moves, there will be no sliding phenomenon, and the ultra-high precision level (UM) can be achieved.

2、磨耗少能長時間維持精度傳統的滑動引導，無可避免的會因油膜逆流作用造成平臺運動精度不好，且因運動時潤滑不充份，導致運行軌道接觸面的磨損，嚴重影響精度，而滾動導引的磨耗非常小，故機臺能長時間維持精度。

2. Less wear can maintain the accuracy for a long time. The traditional sliding guidance will inevitably cause poor motion accuracy of the platform due to the countercurrent effect of oil film, and the insufficient lubrication during movement will lead to the wear of the contact surface of the running track, which seriously affects the accuracy. However, the wear of rolling guidance is very small, so the machine can maintain the accuracy for a long time.

3、使用高速度運動且大幅降低機臺所需驅動馬力由于直線導軌移動摩擦力非常小，只需較小動力便能讓床臺運行，尤其是在床臺的工作方式為經常性往返運動時，更能明顯降低機臺點力損耗量，且因其摩擦產生的熱度較小，可適用于高速運行。

3. Use high-speed movement and greatly reduce the driving horsepower required by the machine. Because the moving friction of the linear guide rail is very small, the bed can be operated with less power. Especially when the working mode of the bed is regular round-trip movement, it can significantly reduce the point force loss of the machine, and the heat generated by its friction is small, so it is suitable for high-speed operation.

4、可同時承受上下左右的負荷由于直線導軌特殊的束制結構設計，可同時承受上下左右方向的負荷，不想滑動導引在平行接觸面方向可承受的側向負荷輕，易造成機臺運行精度不好。

4. It can bear up, down, left and right loads at the same time. Due to the special beam structure design of the linear guide rail, it can bear the loads in the up, down, left and right directions at the same time. It does not want to slide and guide. The lateral load that can be borne in the direction parallel to the contact surface is light, which is easy to cause poor operation accuracy of the machine.

5、組裝容易并具互換性組裝時只要銑削或研磨床臺上導軌之裝配面，并依建議之步驟將導軌，滑塊分別特定扭力固定于機臺上，既能重視加工時的高精度，傳統的滑動導引，則須對運行軌道加以鏟花，既費事又費時，且一旦機臺精度良，又必須在鏟花一次，直線導軌具有互換性，可分別更換滑塊或導軌是直線導軌組，機臺即可重新獲得高精密度的引導。

5. The assembly is easy and interchangeable. During assembly, as long as the assembly surface of the guide rail on the machine table is milled or grinded, and the specific torque of the guide rail and sliding block are fixed on the machine table according to the recommended steps, it can not only pay attention to the high precision during processing, but also the traditional sliding guidance, the running track must be scratched, which is both time-consuming and time-consuming. Once the machine table precision is good, it must be scratched again, The linear guide rail is interchangeable. The sliding block or guide rail can be replaced to the linear guide rail group respectively, and the machine can regain high-precision guidance.

6、潤滑結構簡單滑動引導若潤滑不足，將會照成接觸面金屬直接摩擦損耗床臺，而滑動導引要潤滑充足并不容易，需要在床臺適當的位置鉆孔供油，直線導軌則已在裝置油嘴，可直接以注油槍打入油脂，亦可換上專用油管接頭鏈接供油油管，以自動供油機潤滑。

6. The lubrication structure is simple. If the sliding guide is not lubricated enough, it will cause direct friction loss of the metal on the contact surface of the bed. However, it is not easy for the sliding guide to be lubricated enough. It is necessary to drill holes at the appropriate position of the bed for oil supply. The linear guide rail has been installed at the oil nozzle of the device, and the grease can be directly injected with the oil gun. It can also be replaced with a special oil pipe joint to link the oil supply pipe to lubricate the automatic oil supply machine.
