AT-FC Right Angle Precision Planetary Gearbox 15

Product Overview

The AT-FC right angle precision planetary gearbox is a high-strength, 90-degree gear reducer designed for applications requiring compact installation, excellent torque density, and precise motion control. Utilizing high-precision spiral bevel gears made from nickel-chromium alloy steel (SCM415, hardened to HRC60), the AT-F right-angle gearbox delivers exceptional durability, rigidity, and long-term accuracy.

The AT-FC right angle precision planetary gearbox combines a highly efficient planetary reduction mechanism with a precision-cut right-angle spiral bevel gear stage, ensuring smooth operation, low noise, and minimal transmission error. With a wide reduction ratio range (single stage 1:3 to 1:10; double stage 1:12 to 1:100), the AT-F/AT-FC right angle precision planetary gearbox offers flexibility for a broad spectrum of industrial automation systems.

Designed for space-constrained applications, the AT-FC right angle precision planetary gearbox offers a compact frame size range from 55 mm to 220 mm, while still delivering output torque from 15 Nm up to 1600 Nm. Output configurations include single shaft, dual shaft, hollow shaft, hollow flange, keyless tapered shaft, and linear screw-driven types — making the AT-FC “hollow clamp output” series ideal for equipment requiring direct shaft-through output or easy coupling to machine load.

The AT-FC right angle precision planetary gearbox supports mounting on five different faces, enabling flexible machine layout and simplifying equipment integration. With a motor compatibility range of 50 W to 15 kW, this series is widely used in servo systems, CNC machinery, robotics, packaging lines, conveying automation, and high-precision manufacturing.
