■ Features For PLFS Series Planetaty Gearbox ( Spur Gear )

The PLFS Series Inline Planetary Gearbox is a high-performance coaxial motion control solution engineered for precision integration with AC servo motors and stepper motors. Featuring a straight-through inline architecture and a sturdy square output flange, this series enhances overall structural rigidity and mounting stability while achieving power transmission efficiency exceeding 95%. Internal precision planetary gears undergo rigorous carburizing, quenching, and tooth profile modification, ensuring maximum torque output, reduced wear, and quiet, low-vibration operation during continuous duty. To meet broad industrial automation requirements—from light positioning stages to heavy-duty automation—the series encompasses a complete range of frame sizes, including PLFS060, PLFS090, PLFS120, and PLFS160. With its high concentricity, durable build quality, and exceptional cost performance, the PLFS planetary gearbox is widely applied in packaging machinery, CNC equipment, automated assembly lines, industrial robotics, and precision drive systems.
