SRA133H/SRA166H/SRA210H

NACHI ROBOT SRA SERIES - SPOT WELDING SRA133

Max Payload : 133 – 210 KG (wrist) 

 1. Improved reliability for welding cables and hoses

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

2. Shortened the startup time

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

3. 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%.

4. Improved accessibility

  • When compared to the existing A-Trac, we have decreased the interference range of the wrist 27%, making access to narrow places possible.

5. Speed

  • The hollow arm can also operate at the same high speeds as the SRA.
