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. |
