■ Features For PLFK Series Planetaty Gearbox ( Spur Gear )
The PLFK Series Inline Planetary Gearbox is a high-precision coaxial motion control solution engineered for direct integration with AC servo motors and stepper motors. Featuring a straight-through inline architecture, this series directly aligns input and output drive axes, achieving high power transmission efficiency exceeding 95% along with excellent torsional rigidity. Internal spur planetary gears undergo advanced carburizing, quenching, and tooth profile modification to guarantee high torque density, smooth engagement, and quiet operation during demanding continuous duty cycles. To fit broad industrial requirements—ranging from light positioning stages to heavy-duty automated machinery—the series offers a comprehensive size range including PLFK060, PLFK090, PLFK120, PLXK142, and PLFK160. Equipped with a sturdy square output flange, the PLFK inline planetary gearbox serves as a reliable drive component for CNC equipment, packaging lines, printing machines, and industrial robotics.
