Air inlet fitting: Temperature Range -20°C to 120°C

Q: What is the primary function of an air inlet fitting in air bearing systems?

The air inlet fitting regulates and distributes compressed air to the bearing pad, maintaining precise pressure and flow rates necessary for creating a stable air film that enables frictionless movement.

Q: How do I select the right air inlet fitting for my application?

Consider operating pressure requirements, flow rate needs, connection type compatibility with existing systems, material compatibility with your environment, and required filtration level based on air quality.

Q: What maintenance is required for air inlet fittings?

Regular inspection for leaks, periodic filter replacement (every 6-12 months depending on air quality), seal inspection, and cleaning of internal passages to prevent clogging from contaminants.

Component Specifications

Definition

A specialized pneumatic fitting designed to connect compressed air supply lines to air bearing pads, featuring precise flow control, pressure regulation, and filtration capabilities to ensure consistent air film formation. This component maintains specific pressure differentials and flow rates required for non-contact levitation in precision industrial applications.

Working Principle

Operates by receiving compressed air from the main supply, regulating pressure through integrated valves or orifices, filtering particulates, and distributing controlled airflow to the bearing pad's porous media or orifice array to create a uniform air film that separates moving surfaces with minimal friction.

Materials

Typically manufactured from corrosion-resistant materials: 316 stainless steel (body), brass (connectors), PTFE or Viton (seals), aluminum alloys (housing). Surface finish: Ra ≤ 0.8 μm for sealing surfaces.

Parameter	Typical range	Notes & selection driver
Flow Rate	5-50 L/min (adjustable)
Leak Rate	< 0.1 mL/min at 0.5 MPa
Connection Type	NPT, BSPP, or quick-disconnect
Filtration Rating	5 μm (standard), 1 μm (optional)
Temperature Range	-20°C to 120°C
Operating Pressure	0.2-0.8 MPa
