Air Inlet Port: Flow Capacity 10-200 L/min at 6 bar

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

The air inlet port precisely regulates and distributes compressed air into the bearing to create a stable air film that separates surfaces, enabling frictionless motion with high precision.

Q: How do I select the correct air inlet port size for my application?

Select based on required airflow (L/min), operating pressure, bearing surface area, and load capacity. Consult manufacturer specifications matching your bearing's orifice count and pressure requirements.

Q: Can air inlet ports be used with different air bearing brands?

While some standardized ports are interchangeable, compatibility depends on thread specifications, pressure ratings, and flow characteristics. Always verify manufacturer specifications before cross-brand usage.

Component Specifications

Definition

The air inlet port is a critical component of air bearing pads, designed to precisely control and distribute compressed air into the bearing's porous media or orifice system. It functions as the entry point where regulated air pressure is introduced to generate a thin, stable air film that separates moving surfaces, enabling near-frictionless motion with micron-level precision. This component ensures consistent airflow characteristics essential for maintaining bearing stiffness, load capacity, and vibration damping in precision manufacturing applications.

Working Principle

Operates by receiving compressed air from the supply system and directing it through precisely engineered channels into the air bearing's distribution network. The port's geometry and internal features control flow rate, pressure distribution, and turbulence to create a uniform air film between bearing surfaces. Bernoulli's principle and viscous flow dynamics govern the formation of the supporting air cushion that eliminates mechanical contact and reduces friction to near-zero levels.

Materials

Typically manufactured from corrosion-resistant materials: 6061-T6 aluminum alloy (anodized), 304/316 stainless steel, or engineered polymers (PEEK, PTFE) for specific applications. Surface finish: Ra ≤ 0.8 μm for metal components. Operating temperature range: -20°C to +120°C for standard versions.
