Basic Concepts of Air Bearing
Air bearings operate on the principle of air pressure. A thin layer of air is pressurized between two surfaces, creating a cushion that eliminates physical contact and allows for frictionless motion.
| Concept | Explanation |
|---|---|
| Aerostatic bearings | Air pressure is constantly supplied to maintain the air film. |
| Aerodynamic bearings | Air flow is generated by the motion of the surfaces, creating the air film. |
| Thrust bearings | Used to support axial loads. |
| Radial bearings | Used to support radial loads. |
