Linear guides have the following features and advantages

1. High precision: The design and manufacturing precision of the linear guide is very high, which can provide extremely high positioning accuracy and repeatability.

2. High rigidity: Linear guide rails have high rigidity, can withstand large loads and torques, and maintain the stability of the mechanical system.

3. Low friction: Due to the use of balls or rollers between the guide rail and the slider, the friction is low, which can provide smooth movement and high efficiency.

4. Long life: The material and manufacturing process of the linear guide ensure its long service life and wear resistance.

5. Quick installation: Linear guide rails usually have a modular design and can be quickly installed into various mechanical systems.
