Maximum torsional backlash is 24 arcmin — a standard-grade figure for positioning where the load doesn't reverse under torque (pick-and-place, rotary indexing tables). Service life is 30,000 hours at 100 rpm and 30 °C, lubricated for life — no oil-change interval to schedule, but the life clock ticks faster above that speed or temperature. ## Sourcing and lifecycle — obsolete, quoted to order Sourced through independent distribution channels; quantities and condition (new-old-stock / pulls) confirmed at RFQ against your BOM line. No pin-compatible or bolt-in alternative is documented by Schneider — if you need a drop-in, the 40 mm flange and the 3:1 ratio are the dimensions to match against a current-series candidate. ## Shaft loads and mounting — C 45 steel, black anodized housing Maximum axial force is 200 N at 100 rpm for 10,000 hours at 30 °C, or 160 N for the full 30,000-hour life — same derating applies to radial force (200 N / 160 N, force applied at mid-span on the output shaft). Torsional rigidity is 1 N·m/arcmin — the wind-up under rated load is predictable enough for open-loop positioning, but a servo loop with encoder feedback would correct the residual compliance.","metaTitle":"Schneider GBX0400031003F Planetary Gearbox, 3:1, 94% Eff","metaDescription":"Schneider Electric GBX0400031003F planetary gearbox, 3:1 reduction, 94% efficiency, 40mm diameter.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Gear Reducers & Gearboxes"],"specifications":{"Efficiency":"94 %","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":"1 N.m/arcmin","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":"200 N 100 rpm, during 10000 hour at 30°C 160 N 100 rpm, during 30000 hour at 30°C","Maximum radial force Fr":"200 N 100 rpm, force applied at mid-distance from output shaft during 10000 hour at 30 °C 160 N 100 rpm, force applied at mid-distance from output shaft during 30000 hour at 30 °C","Gearbox external diameter":"1.6 in (40 mm)","Product or Component Type":"Planetary gearbox","Maximum torsional backlash":"24 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/2a842e8737c1e0b675dca6a9dfd5b228.pdf","sourceUrl":"https://www.se.com/ie/en/product/GBX0400031003F/gearbox-with-straight-teeth-gbx-ø-40-mm-reduction-31-24arcmin-11-n-m/","alternativesUrl":"https://aoctrl.com/api/mcp/products/GBX0400031003F/alternatives.json"},"ai":{"faq":[{"question":"What is the closest alternative to GBX0400031003F in the same family?","answer":"Schneider does not list a direct successor for this 40 mm, 3:1 planetary gearbox.
