Air-bearing turntable
The air-floating turntable is a high-precision rotary platform featuring gas-lubricated bearings for wear-free, low-friction, non-contact operation with ultra-high rotational accuracy and stable rigidity. Its core components include the air bearing, torque motor, and encoder assembly. Gas flows through throttle orifices to form a supporting air film, enabling precise matching between the inner and outer rings of the bearing. Customizable in structure and materials, it supports selection of compatible motors, optical gratings, read heads, and drivers, or can be adapted to integrate customer-provided components.
Ultra-high rotational precisionNo mechanical contact or friction, minimal end-face and radial runout errors, high coaxiality accuracy. Meets micrometer- and nanometer-level precision rotation requirements.
Ultimate smooth motionUniformly suspended and supported by air film; runs smoothly at low speeds without crawling or stalling, and rotates at high speeds without vibration. Motion is seamless throughout with no lag.
Wear-free, long-lastingZero physical contact wear: dust-free, loss-free operation with no long-term precision degradation, significantly reducing equipment maintenance costs.
Stable and balancedUniform gas supply across the entire area ensures sufficient air-film stiffness and excellent load adaptability, maintaining consistent rotation accuracy under both heavy and light load conditions.
Clean and quiet operationNo mechanical friction noise or wear debris; ideal for cleanrooms, laboratories, and other high-precision, ultra-clean environments.
