Application

While traditional bearings are still hampered by friction and vibration, granite air bearings—via the innovative integration of Grade 00 natural granite and high-precision air bearing technology—equip high-end manufacturing with a "smooth-running engine":

1.Inherent Superiority:Selected Grade 00 natural granite, featuring low thermal expansion, high rigidity and excellent shock absorption, suppresses deformation and vibration from the material source, ensuring the equipment remains as stable as a rock.

2.Frictionless High-tech:Air bearing technology generates a micron-scale air film, enabling "levitated" movement of bearing components. This completely eliminates wear and errors, achieving ultimate precision.

3.Full-scenario Adaptability:From semiconductor lithography and ultra-precision measurement to aerospace equipment, it fully meets the stringent requirements of high-end manufacturing for stability, precision and durability, setting a new benchmark for precision support systems.

Main Features

1.Outstanding Material Advantages: Adopting Grade 00 natural granite, this material features a low coefficient of thermal expansion, which can effectively minimize dimensional changes caused by temperature fluctuations. It also boasts high rigidity to withstand heavy loads without easy deformation, as well as excellent shock absorption performance to reduce the impact of external vibrations on bearing operation.

2.Frictionless Operation: By virtue of high-precision air bearing technology, a micron-scale air film is formed between the bearing and mating components, enabling the "levitated" movement of bearing parts. This completely eliminates contact-induced friction inherent in traditional bearings, avoids wear issues, and greatly improves operational precision.

3.Superior Precision Performance: Thanks to its frictionless design and the inherent stability of granite material, granite air bearings can achieve ultra-high motion precision. They meet the stringent precision requirements of ultra-precision manufacturing fields, such as accurate operation in semiconductor lithography and ultra-precision measurement scenarios.

4.Wide Adaptability: Fully compatible with diverse high-end manufacturing needs, these bearings play a vital role with their stable and precise performance across a range of sectors, from semiconductor and precision instrument manufacturing to aerospace equipment.
