A linear guide is composed of guide surface, guide body, rollers, and other parts. Its main characteristics are as follows:

1. High precision: Linear guides have high precision and can meet the requirements of high-precision motion control.

2. Smooth movement: The rolling friction coefficient of the linear guide is small, and the movement is smooth, which can reduce vibration and noise.

3. High load capacity: Linear guides have strong load-bearing capacity and are suitable for heavy-duty applications.

4. Wear resistance: The linear guide rail is made of high wear-resistant materials, which have good wear resistance performance.

5. Easy to install and maintain: The linear guide rail structure is simple, easy to install, and has low maintenance costs.

6. Good anti vibration performance: Linear guides have good anti vibration performance and can work stably in vibration environments.

7. Suitable for various motion modes: Linear guides can adapt to various motion modes such as linear motion and curved motion.

8. Adjustable centering: Linear guides have adjustable centering, which can automatically compensate for guide rail errors and improve accuracy.

In short, linear guides are widely used in various machinery and automation equipment due to their excellent performance, and are essential key components in modern manufacturing.
