Granite Air Bearing: Micron-level Precision for High-end Manufacturing
The granite air bearing is a core functional component made of high-precision natural granite. Integrated with air-floating support technology, it achieves contactless, low-friction and high-precision motion.
The granite substrate boasts prominent advantages including high rigidity, wear resistance, excellent thermal stability and non-deformation after long-term use, which ensures micron-level positioning accuracy and operational stability of equipment under harsh working conditions. -
Granite Air Bearing
The granite air bearing is made of granite material with an extremely low thermal expansion coefficient. Combined with air bearing technology, it has the advantages of high precision, high rigidity, frictionlessness and low vibration, and is suitable for precision equipment.

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.
