Air Bearing Rotary Stage

Product Description

The Air Bearing Rotary Stage is an ultra-precision rotational platform based on air bearing technology, using compressed air as the lubricating medium. The pressurized air forms a thin film that averages out errors, creating a micrometer-scale air layer between the rotor and base to achieve frictionless, wear-free, and high-precision rotational motion. It serves as a critical device in advanced manufacturing, metrology, and scientific research.

  • Continuous high acceleration with zero-friction silent operation;
  • Stable rotational accuracy and high repeatability;
  • High load capacity and strong carrying capability;
  • High rigidity with uniform and stable air-flotation force distribution.
