The AL Series High-Precision Round Flange Helical Planetary Gearbox is a premium inline motion control transmission component specifically designed for demanding industrial automation, servo drive systems, and high-precision positioning machinery. Featuring advanced helical planetary gearing technology, the AL series provides a significantly higher gear contact ratio and smoother meshing engagement compared to traditional spur planetary gearboxes. This engineered design dramatically reduces operational noise and mechanical vibration under continuous high-speed operation, while significantly boosting torque density and delivering ultra-low backlash performance. Internally, the planetary gears are manufactured from premium alloy steel, subjected to strict carburizing, quenching, and tooth-profile precision grinding to guarantee maximum surface hardness, exceptional wear resistance, and long-term positioning accuracy. Enclosed in a robust blue-anodized housing with a high-precision round output flange, the AL series offers outstanding structural rigidity, superior concentricity, and robust loading capacity against heavy radial and axial forces. To satisfy diverse load requirements across automated lines—from compact precision positioning stages to heavy-duty industrial manipulators—the series encompasses a full range of standard frame sizes, including AL070, AL090, AL120, AL155, and AL205. With its exceptional transmission precision, reliable long-term durability, and outstanding cost performance, the AL round flange helical planetary gearbox is widely applied in CNC machine tools, industrial robotics, automated packaging equipment, laser cutting systems, and semiconductor manufacturing lines.
