AT-FH right angle planetary gearbox – Up to 3200 Nm Precision

AT-FH Right Angle Planetary Gearbox – Up to 3200 Nm, High-Strength & Precision

Product Overview

The AT-F / AT-FH right angle planetary gearbox is engineered for high-precision motion control applications requiring compact design, strong load capacity, excellent torsional rigidity, and ultra-smooth operation. Designed with a 90-degree input structure using precision-ground helical bevel gears, these right-angle gear reducers deliver outstanding transmission efficiency, low noise characteristics, and long-term reliability in demanding industrial environments where continuous operation and positioning accuracy are critical.

Manufactured using SCM415 nickel-chromium alloy steel, carburized and hardened to HRC60, the gear sets offer exceptional wear resistance and strength. The combination of a high-efficiency planetary mechanism and a precision bevel gear stage makes this series ideal for robotic systems, servo-driven automation lines, CNC equipment, and applications where installation space is limited but top-tier performance is required.

The AT-F / AT-FH right angle planetary gearbox is available in multiple output configurations, including solid output shaft, dual output shaft, hollow shaft, hollow flange, shrink-disk type, and linear screw options, allowing flexible integration into different machine architectures. With gear ratios from 1:3 to 1:500, frame sizes ranging from 55 mm to 220 mm, and output torque up to 3200 Nm, this series delivers unmatched flexibility and reliable power transmission across a wide range of industrial automation and precision manufacturing applications.
