· Features: It integrates a precision hollow structure with a high-rigidity rotary table, enabling 360° continuous rotation with high positioning accuracy (typically within ±5 arcseconds). Equipped with a preloaded cross roller bearing, it ensures stable rotation and strong radial/axial load capacity. The hollow bore design allows cables, pipes, or workpieces to pass through, optimizing space utilization.

· Material Introduction: The rotary table and base are constructed from high-strength cast iron or alloy steel (quenched and tempered) to enhance rigidity; the precision gear set (if gear transmission is adopted) is made from carburized and quenched alloy steel (e.g., 17CrNiMo6) for wear resistance; cross roller bearings are fabricated from high-carbon chromium bearing steel (SUJ2) for long service life.

· Advantages: The hollow structure eliminates spatial interference, making it ideal for through-hole applications. High positioning accuracy and repeatability (≤±3 arcseconds) meet the demands of precision automation. The integrated design reduces assembly errors, while the cross roller bearing ensures low rotational backlash and smooth operation even under heavy loads.

· Applications: Suitable for robotic welding and handling systems, precision indexing worktables in CNC machining, vision inspection stations in automated production lines, semiconductor wafer handling equipment, laser marking/engraving machines, and rotary positioning units in medical device automation.
