{"id":"nachi-robotics-sra166l","model_id":"SRA166L","name":"Nachi Robotics SRA166L","summary":"The Nachi SRA166L is a six-axis articulated industrial robot. It is intended for spot welding, machine tending, material handling, palletizing, and dispensing. The document lists a 166 kg payload, 2951 mm reach, ±0.15 mm position repeatability, and 980 kg robot mass.","study_notes":["The SRA series is designed for robotic spot welding in automotive applications.","The document specifies FD controllers for SRA series robots; no matching controller id is in the provided reference list.","The specification table lists SRA120EL-01, SRA133L-01, and SRA168L-01; the page title and additional information identify SRA166L with 166 kg payload and 2951 mm reach.","SRA series payloads range from 100 kg to 240 kg, with floor-mount, invert-mount, and long-reach models over 3 meters.","Hollow-arm SRA models route spot welding utilities internally: cooling water, weld power, signals, and servo gun cables.","Nachi's integrated spot weld timer is available in AC and DC versions; it is programmable from the robot teach pendant and stores weld results for traceability.","Pressure calibration supports up to 10 points for spot welding pressure accuracy.","The document states that the controller display shows axis labels J1 through J6."],"safety_notes":["Operating height limit: not higher than 1,000 m above sea level; at higher altitudes the permitted temperature is affected by height.","No condensation is allowed.","Explosion proof is not available.","Noise level is 79.6 dB, measured as A-weighted equivalent sound level under JB-Z 873-1 (ISO 11201) at maximum payload and maximum speed."],"sources":[{"url":"https://www.nachirobotics.com/product/sra166l/","title":"SRA166L","accessed":"2026-10-25"}],"verification":{"status":"source_checked","checked_at":"2026-10-25","values":8,"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":2951,"repeatability_mm":0.15,"weight_kg":980,"operating_temp_min_c":0,"operating_temp_max_c":45,"joints":[],"protocols":[],"standards":[],"error_codes":[]},"url":"https://machineschema.com/hardware/nachi-robotics-sra166l","license":"https://creativecommons.org/licenses/by/4.0/"}
