USP-Mx Ultra-High Precision Air Bearing Rotary Stages

Short Description:

Ultra-High Precision & Unmatched Motion Stability

  • Delivers industry-leading axial runout as low as 25nm and radial runout as low as 30nm across the series, with the largest M250/M200 models maintaining 25nm axial runout for ultra-smooth rotation.
  • Achieves exceptional repeat positioning accuracy down to ±0.2 arcseconds (M200/M250), ensuring sub-micron level positioning consistency for the most demanding metrology and manufacturing applications.
  • All runout and accuracy data is verified via lion standard ball + spindle error analyzer in a controlled laboratory environment, guaranteeing reliable, traceable performance.
  • Axial runout and radial runout are measured in a laboratory environment using a Lion standard ball + spindle error analyzer.
  • Load capacity is measured under 0.5 MPa gauge pressure.
  • Stiffness is measured under central load with 0.5 MPa gauge pressure.
  • Maximum speed can only be achieved with optional motor, grating ruler resolution, and corresponding driver support.

. High Rigidity & Robust Load Capacity

  • Boasts superior axial stiffness up to 1320N/μm and radial stiffness up to 300N/μm (M250 model), delivering exceptional rigidity to resist deflection under heavy loads and maintain precision during dynamic operation.
  • Supports a wide range of load capacities: axial load from 360N to 4320N and radial load from 120N to 720N, making it suitable for both light-weight high-speed tasks and heavy-duty industrial applications.
  • Rigidity and load capacity are tested under 0.5MPa gauge pressure (center load condition), ensuring real-world performance matches specification.

High-Speed Rotation & Flexible Customization

  • Offers a broad speed range, with the compact M80 model reaching a maximum speed of 15,000rpm, ideal for high-speed inspection, wafer processing, and micro-manufacturing.
  • Equipped with direct drive motors or brushless motors (fully customizable) to match specific application requirements, eliminating gear backlash and enabling silent, maintenance-free operation.
  • Low Friction, Zero Wear & Long Service Life

    • Utilizes advanced air bearing technology to create a completely non-contact, frictionless support between the rotor and stator, eliminating mechanical wear, lubrication needs, and particle generation.
    • Ensures ultra-smooth, vibration-free rotation, critical for high-precision optical inspection, semiconductor manufacturing, and metrology equipment where contamination and vibration are prohibited.
    • Significantly reduces maintenance costs and extends service life compared to traditional mechanical bearing rotary stages.

     Compact, Modular Design & Wide Compatibility

    • Features a compact, integrated mechanical design with a through-hole structure, easy to integrate into automated production lines, inspection systems, and scientific research equipment.
    • Available in 5 standard models (M80/M100/M150/M200/M250) with bearing diameters from 80mm to 250mm, covering a full range of application scenarios from micro-precision to heavy-duty industrial use.
    • Optimized air consumption (18L to 40L/min) ensures energy efficiency while maintaining stable air film support, reducing operational costs.
    • Additional Unique Features (English)

      • Non-Contact, Contamination-Free Operation: Perfect for cleanroom environments (semiconductor, biotech, optics) where mechanical contact and lubricants are forbidden.
      • Ultra-Low Motion Error: Minimizes tilt, wobble, and error motion, enabling sub-nanometer level motion accuracy for ultra-precision machining and metrology.
      • Customizable Solutions: Supports tailored motor types, encoder resolutions, and interface configurations to meet specific customer requirements.
      • High Stability Under Dynamic Loads: Maintains precision even during high-speed rotation and heavy load applications, ensuring consistent performance across all operating conditions.
