13.1. Product features (1) The slide rail and slider move relative to each other through the cyclic rolling of steel balls. The end caps and bottom seals at both ends can effectively prevent dust and other foreign objects from entering the interior of the slider. Lubricating the steel ball circulation track through a nozzle provides sufficient and convenient lubrication. (2) Adopting a four row circular arc O-shaped arrangement design, it can withstand greater torque while possessing high rigidity and high load capacity. (3) The friction mode of the linear sliding rail is rolling friction, with a friction coefficient reduced to 1/40 of the sliding rail, and the difference between dynamic and static friction is very small. Therefore, the linear sliding rail has good follow-up performance, which is beneficial for improving the response speed and sensitivity of the CNC system. It can achieve seamless motion and has high positioning accuracy. (4) The friction resistance of the linear sliding rail is small, lubrication is convenient and effective, and the contact surface wear is low, so the accuracy and performance are stable and long-lasting. (5) Due to the small frictional resistance, the driving power and mechanical structure can be reduced, thereby achieving miniaturization, high-speed, and low energy consumption of the equipment. (6) The linear slide rail is installed on the processed plane according to certain assembly steps, and can achieve high accuracy without special treatments such as scraping and grinding. The slide rail slider is interchangeable, easy to replace, and does not affect the accuracy of use. In order to effectively prevent cutting or foreign objects from entering the interior of the slider through bolt holes, which affects the operating accuracy and service life of the linear slide rail, users can choose LS dustproof steel strip series products. The dustproof steel strip is made of stainless steel and is clamped on the slide rail, effectively preventing the accumulation of foreign objects in the installation hole. Advantages of dust-proof steel belt: (a) All installation holes on one slide rail only require one dust-proof belt; (b) The dust belt can be disassembled and used again; (c) 2627 is easy and fast to install; (d) To avoid jamming of a slide rail due to improper installation of multiple dust caps; (e) Combined with the sealing element on the slider, it has better dust prevention effect
