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.

直线导轨之所以被称之为“直线”导轨，是因为它是用于直线往复运动的，可以在高负载的情况下实现无卡顿高精度的直线运动。其中，直线导轨的导轨用作支撑和引导运动部件，按照设定的方向做直线往复运动。

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.

直线导轨应用的领域和行业非常广泛，如电机机械，机器手、激光机、印刷机、雕刻机、点胶机、医疗设备、摄影行业等都可以将直线导轨作为工业配件，应用可以说是非常广泛。

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.

南京春信自动化设备有限公司生产的直线导轨滑块主要有法兰型和四方型，其中四方型可分为高组装和低组装，法兰型直线导轨滑块和四方型直线导轨滑块各有两种不同的尺寸，为法兰式标准型、法兰式加长型、四方高组装型分为标准型和加长型，四方低组装型分为短型和标准型，都与相同尺寸的导轨相对应，客户在选购时需要根据不同的使用场景来选择对应合适的尺寸直线导轨产品。

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.

通常情况下，直线导轨15-25大小的中小型导轨适用于小型设备，如机械手，30-45的直线导轨承载量较大，适用于大型的设备。

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.
