The ESTUN ER20B-2300-HI is a long-reach, high-performance 6-axis industrial robot in the Small Load Series, engineered to combine extended working envelope, high payload capacity, and robust motion control for demanding automation applications. With a 20 kg payload and a 2,300 mm reach, this robot delivers stable, precise motion and excellent repeatability — ideal for tasks such as material handling, palletizing, loading/unloading, machine tending, and large-area transfer in modern manufacturing lines.
Designed with a reinforced mechanical structure and optimized dynamic performance, the ER20B-2300-HI supports heavy-duty cycles with high operational stability and precision, enabling integrators to cover large production areas without multiple robot stations.
The ER20B-2300-HI and ER20-2300-HI share the same 20 kg payload, 2,300 mm reach, and 6-axis configuration, but the “B” suffix typically indicates a variant with reinforced body structure or optimized kinematics tailored for smoother dynamic performance and enhanced rigidity within similar size-class articulated robots. Both variants belong to the Small Load Series but may have minor differences in weight distribution or joint design that impact cycle stability and ease of debugging in larger workspaces.
Payload & Reach: Both models lift up to 20 kg at 2,300 mm reach.
Configuration: Both are 6-axis articulated robots for general industrial automation.
Series Positioning: The “B” variant highlights differences in design refinement and intended industrial use, such as enhanced rigidity or motion smoothness under load.
