Linear guide rail is a device designed to support and guide moving parts so that they can perform reciprocating linear motion in a specific direction. Compared with linear bearings, linear guide rails have higher rated load capacity and motion accuracy in moving components of the same volume, while also being able to withstand certain torque loads.

1. Slide rails and sliders: Slide rails are the main supporting components of linear guide rails, while sliders are responsible for sliding on the slide rails to achieve linear motion. The design and material selection of slide rails and sliders directly affect the load-bearing capacity and motion accuracy of the guide rails.

‌2. Steel balls and steel ball retainers: Steel balls roll between sliders and slide rails to reduce friction and achieve low-friction linear motion. Steel ball retainers are used to fix steel balls to prevent them from falling off.

‌3. Lubrication system: Including self-lubricating components, oil nozzles, oil pipe joints, etc., to ensure the smooth operation of the guide rails and extend their service life.

4. Dustproof system: such as SUS304 quick-install dustproof steel belt, oil scraper, bottom sealing dustproof sheet, etc., are used to prevent dust and impurities from entering the guide rail and affecting its performance.

1. High precision and good reproducibility: linear guide rail adopts smooth rolling motion, small friction coefficient, small difference between static friction and dynamic friction, no idling and slipping even in micro-feeding, and can achieve μm-level positioning accuracy with good reproducibility.

2. Low friction resistance, long-term accuracy: The rolling friction resistance of linear guide rail can be reduced to 1/20~1/40 of the friction resistance of sliding guide rail, the lubrication structure is simple and the effect is excellent, the wear of friction contact surface is the lowest, so the walking accuracy can be maintained for a long time.

3. High load bearing capacity: linear guide rail is optimized in design, can bear radial, reverse radial and lateral loads at the same time, and can improve its rigidity and load capacity by applying preload and increasing the number of sliders.

‌4. Suitable for high-speed applications‌: Due to the low friction resistance, the driving horsepower requirement for the equipment is low, and the energy saving effect is significant, especially suitable for mechanical equipment that needs to run at high speed‌.

‌5. Easy to assemble and interchangeable‌: The linear guide rail is easy to install. It only needs to be assembled on the milled or ground mounting surface to reproduce the accuracy, and the slider is interchangeable. It can be arbitrarily installed on the same model of slide rails to maintain the same smoothness and accuracy, which is convenient for assembly and maintenance‌.

‌1. Rust prevention‌: During installation and use, ensure that your hands are clean and avoid direct contact with sweat or water stains on the guide rails. In summer or humid environments, apply mineral oil to the guide rails regularly to prevent rust‌.

‌2. Environmental cleanliness‌: It is very important to keep the guide rails and their surroundings clean. Even if tiny dust enters the guide rails, it will increase wear, vibration and noise. Therefore, ensure that the working environment is clean and avoid the intrusion of dust and impurities‌.

‌3. Correct installation‌: When installing the guide rail, professional tools should be used to avoid using a hammer to directly hit the guide rail. Strong stamping and pressure transmission through the roller body are prohibited. Be careful during installation to ensure that the guide rail fits tightly with the installation surface.

4. Lubrication maintenance‌: Regularly check and maintain the lubrication status of the guide rail to ensure that it will not be damaged due to lack of lubrication during operation. Proper lubrication can reduce friction and extend the service life of the guide rail.

5. Avoid excessive load‌: During use, the rated load of the guide rail should be avoided to prevent damage to the guide rail or affect its accuracy. Reasonably design the load distribution and motion path to ensure that the guide rail operates within a safe range.

6. Regular inspection‌: Regularly check the operating status of the guide rail, including lubrication, wear and noise level. Find problems in time and perform maintenance or replace damaged parts to ensure the stable operation of the guide rail.
