Aerostatic Bearings: The Ultimate Guide to Frictionless Motion

Aerostatic bearings are a type of non-contact bearing that uses a pressurized air film to separate the bearing surfaces. This eliminates friction and wear, resulting in smooth, precise, and long-lasting operation.

| Benefits of Aerostatic Bearings |
|---|---|
| Zero Friction: No contact between surfaces eliminates friction and wear. |
| High Precision: Air film provides precise control over spacing and movement. |
| Long Life: No wear means extended lifespan, reducing maintenance costs. |

| Applications of Aerostatic Bearings |
|---|---|
| Precision Machining: High-precision spindles and slides. |
| Medical Imaging: MRI and CT scanners. |
| Semiconductor Manufacturing: Wafer handling and inspection. |

Success Stories of Aerostatic Bearing Applications

• Improved Product Quality in Precision Machining: A leading aerospace manufacturer reported a 30% increase in product quality after switching to aerostatic bearings on their grinding spindles.
• Reduced Maintenance Costs in Medical Imaging: A major hospital saved $500,000 in annual maintenance costs by installing aerostatic bearings in their MRI scanners.
