The AF Series High-Precision Helical Planetary Gearbox is a premium inline motion control transmission component specifically engineered for demanding industrial automation, servo drives, and high-precision positioning systems. Utilizing advanced helical gear technology, the AF series provides a higher gear contact ratio and smoother meshing engagement compared to conventional spur planetary gearboxes. This design dramatically reduces operational noise and vibration under continuous high-speed duty while boosting torque density and delivering ultra-low backlash performance. Internal planetary gears are manufactured from high-strength alloy steel, subjected to rigorous carburizing, quenching, and precision tooth grinding to guarantee maximum surface hardness and exceptional wear resistance. Enclosed in a high-rigidity housing with a sturdy square output flange, the AF series provides superior structural mounting rigidity and high load-carrying capacity against external radial and axial forces. To satisfy broad industrial automation requirements—from precision laser processing to heavy-duty industrial manipulators—the series encompasses a complete range of standard frame sizes, including AF060, AF090, AF115, AF140, and AF180. With its exceptional transmission accuracy, robust stability, and long service life, the AF helical planetary gearbox is widely utilized in CNC machine tools, laser cutting equipment, industrial robotics, semiconductor manufacturing, and automated packaging lines.
