EtG-ForceDrive
High-Torque Servo Reducer
EasternGear’s High-Torque Servo Reducers are engineered based on powerful torque and unrivaled durability, delivering peak performance in heavy-duty environments such as heavy machinery and large-scale industrial equipment. Through innovative Globoid design technology, we maximize power efficiency while dramatically enhancing space utilization for large drive units with a more compact structural design.
◆ Key Features
- [High Load Capacity] Superior Power via Simultaneous Surface Contact
By distributing loads across multiple teeth through simultaneous surface contact, our reducers achieve over 200% more durability compared to standard worm reducers while minimizing wear and heat generation.
- [Exceptional Torque Density] 30% More Compact
Delivers the same performance as conventional worm reducers with a size reduction of 30% or more. This allows for the construction of powerful power transmission systems in confined spaces while reducing the overall weight of the equipment.
- [Energy Optimization] High Transmission Efficiency up to 95%
Our design minimizes dynamic friction, improving efficiency by more than 10% compared to typical worm gears. This reduces operating costs for large-scale facilities by minimizing energy loss and maintains consistent efficiency even in harsh conditions like high heat and humidity.
- [Global Standard Reliability] ANSI/AGMA 6135-A02 Compliance
Based on verified data and precision machining technology, we meet the stringent quality requirements of the global market, ensuring stable operation over the long term.
◆ Applications
- Heavy Industry & Construction: High-torque drive units for excavators, large cranes, winches, etc.
- Automated Manufacturing Lines: High-load handling processes for EV body transport and large presses.
- Plant Equipment: Continuous heavy-load devices in steel mills, mining equipment, etc.
- Energy & Infrastructure: High-rigidity drive units for solar trackers, dam sluice gate controls, etc.
