{"id":"nachi-robotics-sra250-01","model_id":"SRA250-01","name":"Nachi SRA250-01","summary":"The Nachi SRA250-01 is a six-axis articulated industrial robot with a 250 kg wrist payload and a 2,792 mm reach. It is floor-mounted and uses AC servo motors, with applications listed as machine tending, material handling, palletizing, and spot welding. The document states that it is paired with a Nachi FD controller and servo-gun software for spot welding.","study_notes":["The specification table lists the robot model as SRA250-01; the page title and additional information use SRA250.","Construction is articulated with six axes and AC servo motor drive.","Applications listed: machine tending, material handling, palletizing, and spot welding.","The document names a Nachi FD controller with 4th-generation servo gun software; this controller has no matching id in the reference list.","Wrist protection is IP67 equivalent; body protection is IP54 equivalent.","A hollow arm series is available for internal routing of spot-welding utilities such as cooling water, weld power, signals, and servo gun cables.","An integrated spot weld timer is available in AC and DC versions, with pressure calibration up to 10 points.","Forearm allowable load for the SRA250-01 column is listed as 20 kg (45 kg at maximum).","Position repeatability is stated to conform to JIS B 8432; noise is measured under JIS Z 8737-1 (ISO 11201)."],"safety_notes":["Explosion proof is not available.","Permitted height is not higher than 1.000 m above sea level; use at higher place affects the permitted temperature.","Operating humidity is 20 to 85 %RH with no dew condensation; installation-face vibration must not exceed 0.5 G (4.9 m/s²).","Noise is 79.6 dB(A) at maximum payload and maximum speed."],"sources":[{"url":"https://www.nachirobotics.com/product/sra250/","title":"SRA250","accessed":"2026-10-25"}],"verification":{"status":"source_checked","checked_at":"2026-10-25","values":30,"method":"llm_source_check"},"updated_at":"2026-10-25","type":"hardware","spec":{"category":"industrial_robot","manufacturer":"nachi-robotics","controllers":[],"axes":6,"payload_kg":250,"reach_mm":2792,"repeatability_mm":0.2,"weight_kg":1030,"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":100},{"name":"J2","range_min_deg":-80,"range_max_deg":60,"max_speed_deg_s":90},{"name":"J3","max_speed_deg_s":95},{"name":"J4","range_min_deg":-360,"range_max_deg":360,"max_speed_deg_s":125},{"name":"J5","range_min_deg":-130,"range_max_deg":130,"max_speed_deg_s":125},{"name":"J6","range_min_deg":-360,"range_max_deg":360,"max_speed_deg_s":190}],"protocols":[],"standards":[],"error_codes":[]},"url":"https://machineschema.com/hardware/nachi-robotics-sra250-01","license":"https://creativecommons.org/licenses/by/4.0/"}
