Engineered for high-torque applications, our hydraulic rotary actuator generates up to 1,000,000 N·m using a planetary gear reduction system. The multi-stage gear train (efficiency ≥92%) reduces input speed while amplifying torque, with each gear tooth case-hardened (depth 1.5 mm, 60 HRC). The housing is fabricated from quenched and tempered steel (34CrNiMo6) with finite element optimized ribs for rigidity. Used in heavy machinery like tunnel boring equipment and offshore platform cranes, it features a lubrication system with oil debris monitoring. A thermal management system prevents overheating during continuous operation. Request high-torque performance curves or visit [https://www.uranustj.com/] for offshore application details.
