Tianjin Uranus' heavy-duty hydraulic rotary actuator is built for demanding industrial applications, featuring a ductile iron housing (QT900-2) and forged steel gears. Capable of torque outputs from 10,000 to 500,000 N·m, it drives large rotating equipment like ship rudders, mining crushers, and wind turbine yaw systems. The design incorporates double-row tapered roller bearings to handle combined radial/axial loads, while the gear teeth undergo shot peening to enhance fatigue life (≥10⁷ cycles). A pressure-compensated flow divider ensures synchronized operation in multi-actuator systems. Request heavy-duty torque specifications or visit [https://www.uranustj.com/] for load capacity tables.
