- Manufacturer: [Nachi Robotics](https://machineschema.com/manufacturer/nachi-robotics.md)

## Safety

- Explosion proof is not available.
- Humidity limit is 20–85% RH with no dew condensation allowed.
- Installation-face vibration must not exceed 0.50 (4.9 m/s²).
- Permitted installation height is not higher than 1,000 m above sea level; higher altitude affects permitted temperature.

## Study notes

- Uses an AC servo drive system and articulated construction.
- Applications listed: machine tending, material handling, palletizing, spot welding, dispensing.
- Paired with Nachi FD controllers; no matching FD controller id is available in the reference list.
- Hollow arm routes pneumatic, power, and servomotor cables internally, eliminating external dress packages.
- SRA-H series payloads range from 100 kg to 220 kg and include floor-mount, invert-mount, and long-reach models over 3 m.
- J3 and J4 rows list alternative ranges; the document does not clearly assign them to SRA100H-01 versus SRA133HL-01.
- J2 range is listed as -1.40 to +1.05 rad but also as -60° to +60°; the source values are inconsistent.
- JIS B 8422 compliant; sound level measured per JIS Z 9737-1 (ISO 11201).
- Table lists 2,954 mm maximum reach for SRA133HL-01; additional information lists 2,654 mm reach for SRA100H.
- Wrist payload column also lists 133 kg for SRA133HL-01; SRA100H-01 is 100 kg.
- Forearm/Foresim load is listed as 20 kg.
