Technical details and manufacturing context for Bearing Pad/Orifice Plate

Definition
The Bearing Pad/Orifice Plate is a critical component within an Air Bearing System, serving as the interface between the bearing surface and the moving element. It incorporates precisely machined orifices that regulate the flow of compressed air, creating a thin film of air that enables frictionless motion and precise positioning in industrial applications.
Working Principle
Compressed air is supplied to the bearing pad, which distributes it through multiple small orifices. The air exits through these orifices, creating a pressurized air film between the pad and the opposing surface. The orifice plate controls the airflow rate and pressure distribution, maintaining a consistent gap for smooth, low-friction movement.
Common Materials
Stainless Steel, Aluminum Alloy, Ceramic
Technical Parameters
  • Overall dimensions including thickness, width, and length of the bearing pad/orifice plate assembly (mm) Customizable
Components / BOM
  • Bearing Surface
    Provides smooth contact area for air film formation
    Material: Stainless Steel
  • Orifice Array
    Distributes compressed air through precisely sized holes
    Material: Stainless Steel
  • Mounting Holes
    Secures the plate to the bearing assembly
    Material: Same as base material
Engineering Reasoning
0.1-10 bar differential pressure across orifice
15 bar differential pressure causing plastic deformation of orifice edges
Design Rationale: Orifice edge erosion due to cavitation at pressure differentials exceeding 10 bar, where local pressure drops below vapor pressure of air (approximately 0.02 bar at 20°C), causing bubble formation and collapse with microjet impacts exceeding 1000 MPa
Risk Mitigation (FMEA)
Trigger Particulate contamination exceeding 5 μm diameter in airflow
Mode: Orifice clogging leading to pressure imbalance and bearing instability
Strategy: Installation of dual-stage filtration with 1 μm absolute rating upstream
Trigger Thermal cycling between -20°C and 80°C at 5 cycles/hour
Mode: Differential thermal expansion between pad material (aluminum, α=23.1×10⁻⁶/K) and orifice plate (stainless steel, α=17.3×10⁻⁶/K) causing microcracks
Strategy: Use of matched coefficient of expansion materials or flexible mounting with silicone elastomer (shear modulus 0.5 MPa)
