The continuous output torque is 115 N.m at 100 rpm and 30 °C, with a maximum intermittent torque of 184 N.m under the same conditions — the gap between continuous and peak tells you the thermal margin for short overloads during acceleration or reversing cycles. Rated service life is 30,000 hours at 100 rpm and 30 °C, which is roughly 3.4 years of continuous operation at that speed. The gearbox is lubricated for life, so no field maintenance on the oil — the housing is sealed at the factory. Efficiency is listed at 94 %, meaning about 6 % of input power is lost to friction and churning losses in the gear mesh. For a 115 N.m output at 100 rpm, that's roughly 1.2 kW input to deliver 1.13 kW at the shaft — the heat rejection is modest but needs to be considered in a sealed enclosure. ## Mechanical limits — axial and radial load capacity Maximum axial force (Fa) is 2100 N at 100 rpm for the full 30,000-hour service life, or 2800 N if you accept a shorter 10,000-hour life. Radial force (Fr) applied at mid-span on the output shaft is 1500 N for 30,000 hours, or 2000 N for 10,000 hours. These are the bearing limits — exceeding them shortens life non-linearly. Torsional rigidity is 12 N.m per arcminute of wind-up, and maximum torsional backlash is 8 arcminutes. For positioning applications, that backlash is the lost motion between input and output when reversing direction — 8 arcmin at the output translates to roughly 0.13° of positioning uncertainty before the load picks up. The shaft output seal is rated IP54, meaning dust-protected and splash-resistant — fine for most industrial environments but not for washdown or submerged service. Ambient operating range is -25 to 90 °C, which covers most indoor factory conditions without derating. ## Lifecycle status — obsolete, sourced through independent channels Schneider Electric has marked the GBX1200030704F as obsolete. No official successor or cross-reference is recorded from the manufacturer — the GBX series has been superseded by newer planetary gearbox families with different mounting interfaces and ratios. Available through independent surplus and broker channels. Quantities are lot-specific and confirmed at RFQ. The gearbox is a mechanical component with no firmware or electronics — condition is visual and dimensional, so a used or NOS unit is typically serviceable if the seals and bearings check out. No pin-compatible direct replacement exists from Schneider Electric's current catalog. A functional replacement would require matching the 120 mm housing diameter, 3:1 ratio, 115 N.m continuous torque, and the output shaft dimensions — expect a different bolt pattern or keyway, meaning a mounting plate adapter.","metaTitle":"Schneider Electric GBX1200030704F planetary gearbox","metaDescription":"Schneider Electric GBX1200030704F planetary gearbox, straight teeth, 3:1 reduction, 115 N.m continuous torque, 94% efficiency.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Gear Reducers & Gearboxes"],"specifications":{"Efficiency":"94 %","Noise level":"65 dB 1 m, no-load","Gear box type":"Straight teeth","Housing Colour":"Black","Shaft material":"C 45","Reduction ratio":"3:1","lifecycle_stage":"current","Housing material":"Black anodized aluminium","Device short name":"GBX","Compatibility code":"GBX","Torsional rigidity":"12 N.m/arcmin","Maximum output torque":"1628.5 lbf.in (184 N.m) 100 rpm 86 °F (30 °C)","Nbr. of units in pkg.":"1","Service life in hours":"30000 h 100 rpm 86 °F (30 °C)","Additional information":"Lubricated for life","Maximum axial force Fa":"2100 N 100 rpm, during 30000 hour at 30°C 2800 N 100 rpm, during 10000 hour at 30°C","IP Degree of Protection":"Shaft output IP54","Maximum radial force Fr":"1500 N 100 rpm, force applied at mid-distance from output shaft during 30000 hour at 30 °C 2000 N 100 rpm, force applied at mid-distance from output shaft during 10000 hour at 30 °C","Continuous output torque":"1017.8 lbf.in (115 N.m) 100 rpm 86 °F (30 °C)","Gearbox external diameter":"4.7 in (120 mm)","Product or Component Type":"Planetary gearbox","Maximum torsional backlash":"8 arc.min","Ambient Temperature For Operation":"-13...194 °F (-25...90 °C)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/aed772fa543d03f55f4c5e07a91b7b83.pdf","sourceUrl":"https://www.se.com/ie/en/product/GBX1200030704F/gearbox-with-straight-teeth-gbx-ø-120-mm-reduction-31-8arcmin-115-n-m/","alternativesUrl":"https://aoctrl.com/api/mcp/products/GBX1200030704F/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy GBX1200030704F and how do I get a price?","answer":"No stock-holding claim; each lot is sourced per request."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/GBX1200030704F","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/schneider/GBX1200030704F when reusing this data.
