{"id":"nachi-robotics-sra166h-01","model_id":"SRA166H-01","name":"Nachi Robotics SRA166H-01","summary":"The Nachi SRA166H-01 is a six-axis articulated industrial robot with a 166 kg wrist payload and 2,654 mm reach. It is floor-mounted and uses an AC servo drive system, intended for spot welding, machine tending, material handling, and palletizing. It is paired with a Nachi FD controller for motion and servo-gun control.","study_notes":["Six-axis articulated robot with AC servo drive and floor mounting.","Uses a Nachi FD controller with 4th-generation servo gun control software for spot welding.","Hollow-arm design routes welding cables and hoses internally to improve cable reliability and reduce interference with peripheral equipment.","For SRA166H-01, allowable static wrist load torque is 960 N·m at J4 and J5, and 520 N·m at J6.","For SRA166H-01, allowable wrist moment of inertia is 100 kg·m² at J4 and J5, and 50 kg·m² at J6.","Position repeatability conforms to JIS B 8432; noise is measured per JIS Z 8737-1 (ISO 11201).","Applications listed are machine tending, material handling, palletizing, and spot welding."],"safety_notes":["Operating ambient conditions: 0–45 °C, 20–85% RH without condensation, and vibration not more than 0.5G (4.9 m/s²).","Permitted height is not higher than 1,000 m above sea level; above that, permitted temperature is affected by height.","A-weighted equivalent sound level is 79.6 dB while operating at maximum speed with rated load."],"sources":[{"url":"https://www.nachirobotics.com/product/sra166h/","title":"SRA166H","accessed":"2026-10-25"}],"verification":{"status":"source_checked","checked_at":"2026-10-25","values":32,"method":"llm_source_check"},"updated_at":"2026-10-25","type":"hardware","spec":{"category":"industrial_robot","manufacturer":"nachi-robotics","controllers":[],"axes":6,"payload_kg":166,"reach_mm":2654,"repeatability_mm":0.15,"weight_kg":1100,"operating_temp_min_c":0,"operating_temp_max_c":45,"joints":[{"name":"J1","range_min_deg":-180,"range_max_deg":180,"max_speed_deg_s":115},{"name":"J2","range_min_deg":-80,"range_max_deg":60,"max_speed_deg_s":105},{"name":"J3","range_min_deg":-146.5,"range_max_deg":150,"max_speed_deg_s":115},{"name":"J4","range_min_deg":-210,"range_max_deg":210,"max_speed_deg_s":175},{"name":"J5","range_min_deg":-125,"range_max_deg":125,"max_speed_deg_s":171},{"name":"J6","range_min_deg":-210,"range_max_deg":210,"max_speed_deg_s":280}],"protocols":[],"standards":[],"error_codes":[]},"url":"https://machineschema.com/hardware/nachi-robotics-sra166h-01","license":"https://creativecommons.org/licenses/by/4.0/"}
