Hollow Rotary Platform Gear Reducer

• 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.

Medical and Testing Industry: Suitable for patient rotating tables in medical imaging equipment (such as MRI and ultrasonic testing), sample turntables in laboratory automated testing, and positioning units of surgical navigation robots. This scenario requires stable operation (vibration ≤0.01mm), high cleanliness (corrosion-resistant materials are required for some scenarios), and compliance with medical device safety standards.

Laser and Optical Industry: Suitable for rotary worktables of laser marking machines (for full-circumference marking of circular workpieces) and lens rotation adjustment mechanisms of optical detection equipment. In this scenario, the hollow hole can be compatible with optical paths or lens cables, and maintain positioning accuracy even at high speeds (up to 300rpm).

One Of The Best Rack and Pinion Manufacturers In China
Kunshan Devotec Automation Co., Ltd. was established in 2012, but its origins trace back to an initial investment by the German company WMH HERION in Qingdao, Shandong Province in 2007. Since then, we have accumulated extensive experience in engineering, manufacturing, and quality control. As a specialist in drive technology, Kunshan Devotec Automation focuses on the production of high-precision gear racks, gears, pinions, gearboxes, linear guideways, and other linear transmission components.
