E-EABT-D100 Air Bearing Rotary Table

✅ Ultra-Precise Direct-Drive Air Bearing Design

• Air bearing technology eliminates mechanical friction and wear, ensuring ultra-smooth, maintenance-free operation for long-term stability.
• Direct-drive motor removes backlash and transmission errors. With a 7872-line encoder, it delivers 0.82 sec resolution (optional 1 Vpp for higher precision) and ≤±2 sec repeatability, meeting sub-arc-second accuracy demands.

• At 5 bar air pressure, axial load capacity reaches 210 N, and radial load capacity is 78 N, suitable for small precision workpieces and fixtures.
• High axial stiffness (102 N/µm) and radial stiffness (38 N/µm), combined with <0.8 µm axial/radial runout, ensure vibration-free, stable performance even at high speeds.

• Max speed up to 2000 rpm (encoder analog mode), with 0.68 Nm rated torque and 1.5 Nm peak torque, ideal for both high-speed positioning and medium-duty rotation tasks.
• Low air consumption of only 8 NL/min, reducing long-term operating costs. Compatible with standard 5 bar factory air supplies for easy integration.

• Compact footprint (110×110×68 mm) with a 100 mm tabletop, a Ø20 mm through-hole, and standard M4 mounting holes for quick installation into multi-axis systems or custom equipment.
• Economical pricing paired with high-end performance, making it a cost-effective air bearing solution for precision testing, optical inspection, and semiconductor applications.

2. Typical Applications

1. Optics & Photonics Testing

   Ideal for angle calibration, eccentricity measurement, and transmittance testing of lenses, prisms, and optical components. The <0.8 µm runout and ±2 sec repeatability guarantee consistent, accurate results for optical inspection systems.
2. Semiconductor & Precision Electronics

   Used for multi-station inspection and processing of wafers, chips, and PCBs. The direct-drive, zero-backlash design and high-speed capability meet the efficiency and precision requirements of semiconductor production lines, while the air bearing avoids contamination risks from traditional bearings.
3. Precision Machining & Metrology

   Suitable for indexing machining, profile inspection, and CMM applications for small precision parts. High axial/radial stiffness resists minor external forces during machining or measurement, ensuring workpiece positioning accuracy and improving product yield.
4. R&D & Academic Labs

   Perfect for high-precision rotation platforms in materials testing, physics experiments, and educational equipment. The compact form factor allows flexible experimental setups, and low air consumption adapts to laboratory air conditions, offering an optimal balance of performance and budget for research scenarios.
