1. Load Capacity: Determines the maximum weight that the guide rail can support without compromising performance.
- Dynamic Load Rating: Indicates the load that the guide rail can handle at a specific velocity without significantly reducing its service life.
- Static Load Rating: Represents the maximum load that the guide rail can withstand without permanent deformation.
2. Accuracy: Measures the deviation from a perfectly straight path.
- Positioning Error: The maximum deviation from the desired position at any point along the travel distance.
- Running Parallelism: The deviation from perfect parallelism between the guide rails.
3. Stiffness: Resistance to deformation under load.
- Linear Stiffness: Indicates the amount of deflection per unit of load applied in the linear direction.
- Torsional Stiffness: Measures the resistance to twisting under load.
4. Travel Length: The maximum distance that the moving component can traverse along the guide rail.
5. Speed: The maximum velocity at which the guide rail can operate without compromising accuracy or stability.
6. Environmental Conditions: Factors such as temperature, humidity, and dust can affect the performance and durability of the guide rail.
