That 96 % figure means only 4 % of the input power is lost as heat in the gear mesh, so the gearbox runs cool enough to skip forced cooling in most servo-driven axes. Straight-tooth planetary design with 30 arcmin maximum torsional backlash. For positioning applications, that backlash is the lost motion between input and output when the direction reverses — 30 arcmin is a standard-precision class, suitable for general indexing and conveyor positioning but not for zero-backlash cam-follower or high-gain servo loops. ## Service life and load limits — 30000 h at 100 rpm Rated service life is 30000 hours at 100 rpm output speed and 30 °C ambient — that is about 3.4 years of continuous 24/7 operation before the grease degrades and gear wear accumulates. The gearbox is lubricated for life, so no maintenance refill interval; the 30000 h figure is the replacement trigger, not a service reminder. Maximum axial force on the output shaft is 200 N at 100 rpm for the 10000-hour rating, dropping to 160 N for the full 30000-hour life. Radial force follows the same pattern: 200 N at mid-span for 10000 h, 160 N for 30000 h. These are the load limits that govern bearing life — a belt-drive or overhung pinion that exceeds 160 N radial will shorten the gearbox life below the datasheet figure. ## Mounting and environment — any position, wide temperature range Mountable in any position — the planetary design and lifetime grease charge mean no oil level to maintain, so the gearbox can be installed shaft-up, shaft-down, or sideways without derating. Housing is black anodized aluminium with C 45 steel shafts — the anodized surface resists corrosion in humid panel environments, and the C 45 shafts provide adequate hardness for keyed or clamped couplings within the 200 N force envelope.","metaTitle":"Schneider Electric GBX0400040401D Planetary Gearbox, 4:1","metaDescription":"Schneider Electric GBX0400040401D planetary gearbox, 40 mm diameter, 4:1 reduction, 96% efficiency, 30 arcmin backlash, 30000 h life.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Gear Reducers & Gearboxes"],"specifications":{"title":"GBX0400040401D","Efficiency":"96 %","Noise level":"55 dB at 1 m, no-load","description":"gearbox with straight teeth GBX- Ø 40 mm- reduction 4:1- < 30arcmin- 15 N.m","Gear box type":"Straight teeth","Housing colour":"Black","Shaft material":"C 45","Reduction ratio":"4:1","lifecycle_stage":"current","Housing material":"Black anodized aluminium","Device short name":"GBX","Moment Of Inertia":"0.022 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,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/15afa7f95c4964deb40e85a52870df8a.pdf","sourceUrl":"https://www.se.com/nl/en/product/GBX0400040401D/gearbox-with-straight-teeth-gbx-ø-40-mm-reduction-41-30arcmin-15-n-m/"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/GBX0400040401D","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/GBX0400040401D when reusing this data.
