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.
Technical Parameters
  • 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
Standards
ISO 1179, ISO 5599, DIN 2353, ISO 1219
