Granite Air Bearing
The core characteristics of granite air bearings can be summarized from three dimensions: material, performance, and application adaptability:
Material Property Advantages
- High rigidity & low thermal expansion coefficient: Granite has excellent physical stability, which reduces the impact of temperature changes on precision.
- Wear-resistant & low vibration: After precision machining of the stone surface, combined with the air film, operational vibration can be further reduced.
Enhanced Air Bearing Performance
- Contactless & wear-free: Air film support eliminates mechanical friction, resulting in an extremely long service life.
- Ultra-high precision: By combining the uniformity of the air film with the geometric accuracy of granite, motion errors can be controlled at the micrometer/nanometer level.
Application Adaptability Advantages
- Suitable for high-precision equipment: Ideal for scenarios with strict precision requirements, such as lithography machines and precision measuring instruments.
- Low maintenance cost: There are no mechanical wear parts; only clean compressed air needs to be ensured.
