SRA133H

SRA133H

The Nachi SRA133H is a high-speed spot-welding robot designed for automotive manufacturing and other demanding welding applications. Engineered with nearly 20 years of servo gun innovation, the SRA133H reduces cycle times, boosts productivity, and lowers operating costs. Its lightweight yet rigid structure enables faster motion with minimal vibration, while the advanced FD controller delivers maximum acceleration and precise weld quality. With 4th-generation servo gun control software, this robot achieves higher motor speeds and smooth electrode contact for consistent, reliable welds. The SRA133H sets the standard for spot welding automation—offering superior performance, efficiency, and return on investment compared to other industrial robots.

Description

Improved reliability for welding cables and hoses

The reliability is improved by stabilizing cable performance to avoid damage due to interference with peripheral equipment.

Shortened the startup time

We greatly decreased the time to check work programs because cables do not interfere with peripheral equipment.

Expanded the operating range of the wrist

Compared to the existing A-Trac, we expanded the operating range of J5 ±10° and J6 ±5° (payload class 210kg), increasing the range of linear movement 20%.

Improved accessibility
