1. High guidance accuracy: Guidance accuracy refers to the straightness of the moving parts moving along the guide rail, as well as the accuracy of the relative positions between the base planes related to it.

2. Sufficient rigidity: The external forces acting on the moving parts are borne by the guide rail surface, so the guide rail should have sufficient rigidity. Therefore, we often increase the width of the guide rail surface to reduce the specific pressure of the guide rail surface, and set up auxiliary guide rails to withstand external loads.

3. Smooth and lightweight guide rail movement: When working with a linear guide rail, it should be lightweight and labor-saving, with a uniform speed, and there should be no crawling phenomenon at low speeds.

4. The structural craftsmanship of the guide rail is good: while ensuring other requirements of the guide rail, the guide rail structure should be simple, easy to process, measure, assemble, and adjust, in order to reduce costs. Specific analysis must be conducted on the guide rails used by different devices, and corresponding design requirements must be proposed.

5. Good wear resistance: The wear resistance of the guide rail refers to the ability to maintain a certain level of accuracy even after long-term use. The guide rail may wear out during use, but the amount of wear should be minimal, and it should be able to automatically compensate or be easy to adjust after wear.

6. High adaptability to temperature changes: The linear guide rail should ensure that it can still work normally under the condition of working temperature changes.
