Neugart WPLN & WPLQE Precision Line Right-Angle Planetary Gearboxes
The Neugart WPLN & WPLQE Precision Line Right-Angle Series (featured model: WPLN090 1-Stage 1:5 Ratio) is Neugart's top-tier, high-precision 90° drive platform, engineered specifically for demanding CNC machine tools, industrial robotics, semiconductor manufacturing, and dynamic positioning servo axes with strict space limitations. By pairing a high-precision ground **spiral bevel input stage with helical planetary gear stages**, the WPLN (precision round output flange) and WPLQE (heavy-load square output flange) series operate with ultra-quiet smoothness and deliver dynamic transmission efficiency up to **96%**. Equipped with robust preloaded tapered roller bearings on the output, these units absorb massive radial and axial shaft loads directly while maintaining total shaft rigidity under high accelerations. Featuring ultra-low torsional backlash (**<2 to <5 arcmin**), the WPLN/WPLQE series is available across 5 modular frame sizes (070, 090, 115, 142, 190) covering ratios from 3:1 to 100:1 with continuous output torques up to **1,800 Nm**. WE DRIVE HONGKONG LIMITED provides technical sourcing, ratio verification, and custom PCS motor adapter selection for Neugart WPLN & WPLQE precision right-angle planetary gearboxes worldwide.
