Neugart PLN & PSN Precision Line Inline Planetary Gearboxes
The Neugart PLN & PSN Precision Line Planetary Gearbox Series (featured model: PLN090 1-Stage 1:5 Ratio) is Neugart's flagship ultra-precision inline drive platform, engineered specifically for high-end CNC machine tools, robotics, printing presses, semiconductor manufacturing, and dynamic servo positioning axes. Built with precision-ground **helical gearing**, the PLN (round output flange) and PSN (square output flange) series deliver exceptionally smooth running, minimal noise emissions, and dynamic transmission efficiency reaching up to **98%**. Featuring preloaded tapered roller output bearings, these gearheads absorb extreme radial (up to 21,500 N) and axial forces directly, maintaining rigid shaft alignment under severe acceleration loads. Offering ultra-low torsional backlash (**<1 to <3 arcmin**), PLN/PSN units are available across 5 modular frame sizes (070, 090, 115, 142, 190) covering 1-stage (3:1 to 10:1) and 2-stage (12:1 to 100:1) reduction ratios with continuous torque ratings up to **1,800 Nm**. WE DRIVE HONGKONG LIMITED provides technical sourcing, ratio calculations, and custom PCS motor adapter selection for Neugart PLN & PSN precision planetary gearboxes worldwide.
