Linear guide is used in many lathes and automatic machines. Linear guide consists of slider and guide. Today we will briefly introduce the slider of linear guide.

直線導軌之所以被稱之為“直線”導軌，是因為它是用于直線往復運動的，可以在高負載的情況下實現無卡頓高精度的直線運動。其中，直線導軌的導軌用作支撐和引導運動部件，按照設定的方向做直線往復運動。

The reason why linear guide rail is called "linear" guide rail is that it is used for linear reciprocating motion and can realize high-precision linear motion without Caton under high load. The guide rail is used as the guiding part for the linear motion and the supporting part for the linear motion.

直線導軌應用的領域和行業非常廣泛，如電機機械，機器手、激光機、印刷機、雕刻機、點膠機、醫療設備、攝影行業等都可以將直線導軌作為工業配件，應用可以說是非常廣泛。

Linear guide rail is widely used in many fields and industries, such as electrical machinery, manipulator, laser machine, printing machine, engraving machine, dispensing machine, medical equipment, photography industry, etc. linear guide rail can be used as industrial accessories, which can be said to be very widely used.

南京春信自動化設備有限公司生產的直線導軌滑塊主要有法蘭型和四方型，其中四方型可分為高組裝和低組裝，法蘭型直線導軌滑塊和四方型直線導軌滑塊各有兩種不同的尺寸，為法蘭式標準型、法蘭式加長型、四方高組裝型分為標準型和加長型，四方低組裝型分為短型和標準型，都與相同尺寸的導軌相對應，客戶在選購時需要根據不同的使用場景來選擇對應合適的尺寸直線導軌產品。

The linear guide sliders produced by Nanjing Chunxin automation equipment Co., Ltd. mainly include flange type and square type. The square type can be divided into high assembly and low assembly. The flange type linear guide sliders and square type linear guide sliders have two different sizes: flange standard type, flange extended type and square high assembly type, which can be divided into standard type and extended type, Sifang low assembly type is divided into short type and standard type, which correspond to the guide rail of the same size. When purchasing, customers need to select the corresponding linear guide rail products of appropriate size according to different use scenarios.

通常情況下，直線導軌15-25大小的中小型導軌適用于小型設備，如機械手，30-45的直線導軌承載量較大，適用于大型的設備。

Generally, small and medium-sized linear guide rails with the size of 15-25 are suitable for small equipment, such as manipulator. The linear guide rail with the size of 30-45 has a large bearing capacity and is suitable for large equipment.
