There are many categories of linear guide rail, which can be applied to low-speed movement or high-speed movement. Due to the special design structure of the linear slide rail, it can bear the loads in the up, down, left and right directions at the same time. Unlike the sliding guide, it can only bear large loads in the direction parallel to the contact surface. When using the linear guide rail, especially in the case of high load, uninterrupted and reciprocating motion, it is necessary to timely lubricate the slider and slide rail. In the case of insufficient lubrication, the service life and accuracy of the 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準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高精設備或特殊機械行業之中。

Linear guide rail is divided into linear guide rail and linear bearing. It is specially made for straight-line reciprocating motion. Linear guideways are mostly used in automatic equipment, such as imported machine tools and automatic welding equipment with high accuracy requirements. Linear bearings are more and more widely used in high-precision equipment or special machinery industries, such as 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.

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，提高很多效率。

It can be applied to both low-speed and high-speed movements, and has high bearing capacity. At the same time, because the linear guide rail movement is in the form of rolling friction, the friction during movement is very small, and only a small amount of power is required to make the loaded slider run, especially when the working mode of the bed table is frequent round-trip operation, it can significantly reduce energy consumption and improve a lot of efficiency.
