This page explains how Air Bearing is classified within Machinery and Equipment Manufacturing. Technical values and manufacturer relationships are research references; confirm the current specification and supplier evidence for each order.
A non-contact bearing that uses a thin film of pressurized air to support loads with minimal friction.
Technical details and manufacturing context for Air Bearing
| Parameter | Typical range | Notes & selection driver |
|---|---|---|
| Load Capacity | 50–5000 N | Depends on bearing size and air pressure |
| Operating Pressure | 0.4–0.8 MPa | Below 0.4 MPa insufficient stiffness |
| Air Consumption | 10–100 L/min | Higher for larger bearings |
| Radial Runout | 0.1–1.0 µm | Precision grade determines valueISO 1101 |
| Axial Stiffness | 50–500 N/µm | Critical for machining accuracy |
| Max Speed | 10000–100000 rpm | Limited by air film stability |
| Operating Temperature | -20–80 °C | Exceeding range affects air viscosity |
| Air Supply Purity | 0.1–1.0 µm | Particle size; oil-free requiredISO 8573-1 |
| Bearing Material | Al2O3 | Alumina ceramic standard |
| Outer Diameter | 10–200 mm | Standard sizes availableISO 15 |
| Bore Diameter | 5–100 mm | Matches shaft sizeISO 15 |
| Weight | 0.1–10 kg | Depends on size and material |

A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
Common materials include porous carbon, ceramic, stainless steel, and aluminum alloy. The choice depends on application requirements such as stiffness, weight, and environmental compatibility. Verify material suitability with the manufacturer.
The reference range is 0.4–0.8 MPa. Below 0.4 MPa, stiffness may be insufficient. Always confirm the required pressure for your specific model and application.
Air supply purity is critical. The reference particle size is 0.1–1.0 µm, and the air must be oil-free. Contaminants can clog orifices or porous media, degrading performance and causing premature failure. Use appropriate filtration per ISO 8573-1.
Common failure modes include loss of air film due to pressure drops, contamination, or excessive load, to solid contact and damage. Also, exceeding operating temperature or speed limits can affect air viscosity and stability. Regular monitoring and maintenance are essential.
