ESTUN ER20-1780

by ESTUN Robotics

The ESTUN ER20-1780 is a 20kg payload 6-axis industrial robot arm from ESTUN Robotics, China's largest publicly listed robot manufacturer. With 1,780mm reach and ±0.05mm repeatability, the ER20 handles welding, machine tending, and material handling tasks in automotive, electronics, and general manufacturing. ESTUN uses its own servo motors and controllers — a rare vertical integration advantage among Chinese robot manufacturers — delivering consistent quality at $18,000–$28,000, roughly 40% below FANUC M-20iD and ABB IRB 4600 equivalents. The ProMotion controller supports visual programming, offline simulation, and integration with EtherCAT, PROFINET, and ROS ecosystems. ESTUN has installed over 30,000 industrial robots across China, Southeast Asia, and Europe, with service centers in Germany, Japan, and India.
