🛞 High-Torque Rotary Table for Heavy-Duty Robotic Welding (EasternGear EGRT Positioner Series)


A New Standard in Precision Positioner Systems
The EGRT Series from EasternGear is a high-torque rotary table optimized for heavy-duty robotic welding automation.
Available in three models—EGRT-2500, EGRT-5000, and EGRT-7500—this lineup supports payloads of 2.5 tons, 5 tons, and 7.5 tons respectively, and is engineered to meet the demands of high-precision applications across diverse industrial environments.


Core Technology: Barrel-Cam Type Globoid Worm Gear System
The defining feature of the EGRT series is its globoid (barrel-type) worm gear drive system.
Unlike conventional cylindrical worm gears, the globoid gear enables wide surface contact, allowing for higher torque transmission, enhanced durability, precise motion control, and compact form factors—all in one.
This makes it especially effective for integration with precision welding equipment and collaborative robotics.


Powerful Torque Meets Precision Control
The EGRT Series supports up to 8,000 kg·m of torque with a repeatability of ±60 arcseconds.
It is ideally suited for precision spot welding, automated fixture positioning, and robotic arm synchronization, while the ±360° continuous rotation supports flexible and dynamic process design.


Optimized Design for Smart Factories
Despite its slim housing, the EGRT series maintains a high-rigidity structure, making it ideal for high-performance welding automation in tight spaces.
It contributes to enhanced productivity and efficiency in multi-axis control systems within the automotive, industrial robotics, and heavy machinery sectors.


Design Flexibility with Complete Turnkey Solutions
EasternGear's globoid worm technology ensures low backlash and stable performance even under high torque.
This provides exceptional design flexibility across various use cases while improving system reliability and longevity in complex robotic setups and industrial production lines.
Backed by decades of worm drive expertise, the EGRT series delivers not just a rotary table, but a next-generation high-precision robotic automation solution.
