Maximum radial force Fr follows the same profile: 200 N at 100 rpm for 10,000 hours, 160 N for 30,000 hours, with the force applied at mid-distance from the output shaft. Torsional rigidity is 1 N·m/arcmin, and maximum torsional backlash is 30 arcmin — this is a commercial-grade positioning gearbox, not a zero-backlash precision stage. Rated service life is 30,000 hours at 100 rpm at 30 °C, lubricated for life with no maintenance interval for grease changes. ## Sourcing reality for an obsolete Schneider GBX gearbox With the GBX0400030402D marked obsolete by Schneider Electric, this part is sourced through independent distribution channels — quantities are confirmed at RFQ and are lot-specific. The gearbox operates in any mounting position over a -25 to 90 °C ambient range, with a C 45 steel shaft and black anodized aluminium housing.","metaTitle":"Schneider Electric GBX0400030402D Planetary Gearbox, 3:1","metaDescription":"Schneider Electric GBX0400030402D planetary gearbox, 3:1 ratio, 96% efficiency, 30 arcmin backlash.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Gear Reducers & Gearboxes"],"specifications":{"Efficiency":"96 %","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","Moment Of Inertia":"0.031 g.cm²","Mounting position":"Any position","Compatibility code":"GBX","Torsional rigidity":"1 N.m/arcmin","Service life in hours":"30000 h at 100 rpm at 30 °C","Additional information":"Lubricated for life","Maximum axial force Fa":"200 N at 100 rpm, during 10000 hour at 30°C 160 N at 100 rpm, during 30000 hour at 30°C","Maximum radial force Fr":"200 N at 100 rpm, force applied at mid-distance from output shaft during 10000 hour at 30 °C 160 N at 100 rpm, force applied at mid-distance from output shaft during 30000 hour at 30 °C","Gearbox external diameter":"40 mm","Product or component type":"Planetary gearbox","Maximum torsional backlash":"30 arc.min","Ambient Temperature For Operation":"-25...90 °C"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/c374b5990c213acf53c765391e8dc320.pdf","sourceUrl":"https://www.se.com/nl/en/product/GBX0400030402D/gearbox-with-straight-teeth-gbx-ø-40-mm-reduction-31-30arcmin-11-n-m/","alternativesUrl":"https://aoctrl.com/api/mcp/products/GBX0400030402D/alternatives.json"},"ai":{"faq":[{"question":"What is the efficiency of GBX0400030402D?","answer":"The listed efficiency is 96 % for this 3:1 straight-tooth planetary gearbox."},{"question":"What is the gearbox type and backlash on GBX0400030402D?","answer":"It is a straight-tooth planetary gearbox with a maximum torsional backlash of 30 arcmin."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/GBX0400030402D","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/GBX0400030402D when reusing this data.
