Advantages of Ceramic Center Rod
- High Mechanical Strength: Because ceramics offer excellent rigidity, the center rod provides reliable structural support under compression or tension.
- Outstanding Wear and Abrasion Resistance: As a result, it resists surface degradation in contact with other moving or abrasive components.
- Thermal and Chemical Stability: Therefore, it operates effectively in high-temperature and corrosive environments without degradation.
- Electrical Insulation: Thanks to its non-conductive nature, it can be used safely in high-voltage and electronic applications.
- Dimensional Precision: Consequently, it is ideal for applications requiring tight tolerances and consistent alignment.
- Material Inertness: This allows for safe use in sensitive environments, including medical, semiconductor, and analytical systems.
