Product Overview
The AT-C series right angle servo gearbox is a premium right-angle gear reducer designed for high-performance automation systems that demand precision, compact size, and exceptional torque density. Combining a spiral bevel gear transmission with a high-efficiency planetary stage, this servo reducer delivers outstanding accuracy, rigidity, and reliability even under continuous industrial operation.
Engineered using SCM415 nickel-chromium alloy steel, carburized and hardened to HRC60, the spiral bevel gears provide superior wear resistance and load-carrying strength. These materials and processing techniques follow widely accepted gear-engineering guidelines from recognized institutions like the American Gear Manufacturers Association (AGMA), ensuring the AT-C Series aligns with global industry expectations for performance and durability.
To further support engineering calculations and application validation, resources such as Engineering Toolbox’s gear formulas and Machine Design’s power transmission insights offer additional technical reference points that many automation engineers rely on when evaluating gear reducers. The AT-C Series follows these same engineering principles, helping users choose the right gearbox based on torque, speed, inertia, and efficiency requirements.
With a combination of ≥98% transmission efficiency, low backlash (≤6 arcmin), and a 20,000-hour service life, this 90-degree servo gearbox is built for long-term productivity. The compact structure is especially useful in machines where motor alignment must be rotated to fit tight installation spaces. The right-angle configuration also simplifies cable routing and reduces the overall machine footprint without compromising output torque or stability.
The hollow output with clamp-type locking offers flexible installation, superior concentricity, and highly stable torque transfer. This makes the AT-C Series particularly suitable for applications with frequent starts and stops, heavy loads, and demanding positional accuracy—common in CNC processing, robotics, and precision automation. Its dual-stage planetary mechanism ensures smooth, vibration-free motion even at high-speed operation, while the reinforced internal bearing system supports torsional rigidity under fluctuating loads, extending the gearbox’s operational lifespan. The AT-C Series also integrates seamlessly with a wide range of servo motors and automated systems, providing engineers with versatile options for performance tuning and machine optimization.
With frame sizes ranging from 55 mm to 220 mm and output torques from 15 Nm up to 1600 Nm, the AT-C series right angle servo gearbox provides excellent adaptability across multi-industry automation needs. Available gear ratios include 1-stage (3–10:1) and 2-stage (12–100:1) configurations, giving users the flexibility to tailor performance to speed or torque requirements.
