BW/XW-IEC Series Vertical Cycloidal Gearbox with IEC Motor Flange combines a high-strength cycloidal pinwheel transmission structure with standardized IEC motor flange input design, providing an integrated drive solution with convenient motor installation, high torque capacity and reliable continuous operation. The vertical flange input structure simplifies equipment assembly and improves system integration efficiency, making it suitable for industrial applications requiring compact installation, high reduction ratio, stable low-speed output and heavy-duty transmission. With a typical output torque range of 100–60,000 N·m and motor power range of 0.12–75 kW, it is widely used in conveyors, mixers, crushers, mining equipment, chemical machinery and heavy industrial drive systems.
