The continuous output torque is rated at 115 N.m, with a maximum peak of 184 N.m — the margin between these two figures defines the overload headroom for acceleration and deceleration events in servo or stepper applications. At 100 rpm and 30 °C ambient, the service life is 30000 hours, and the gearbox is lubricated for life — no maintenance schedule for oil changes. The 96 % efficiency means only 4 % of input power is lost as heat, which keeps thermal rise manageable even in continuous-duty cycles. ## Sourcing reality — obsolete, sourced through independent channels Schneider Electric lists this GBX0800040842D as obsolete. No official successor or cross-reference is recorded from the manufacturer. The part is available through independent surplus and broker channels — quantities are lot-specific and confirmed at RFQ. No pin-compatible or direct bolt-in replacement is documented by Schneider, so a substitution would require verifying the mounting interface, shaft dimensions, and torque curve against the application. For a BOM freeze or legacy machine rebuild, the GBX0800040842D can be quoted to order against the required quantity. ## Mechanical limits that govern the fit The gearbox mounts in any position — horizontal, vertical, or angled — which simplifies integration into existing machine frames. The output shaft is C45 steel, and the housing is black anodized aluminium, giving a corrosion-resistant exterior suitable for dry indoor environments. Shaft output protection is IP54, meaning it resists dust ingress and splashing water at the seal — not rated for washdown or submerged service, but adequate for typical machine-tool or conveyor environments. The torsional backlash is 12 arcmin maximum, and torsional rigidity is 6 N.m/arcmin — these numbers matter for positioning accuracy in pick-and-place or indexing axes where lost motion at reversal must be budgeted. Maximum axial force on the output shaft is 1200 N at 100 rpm for a 10000-hour life, derating to 900 N for the full 30000-hour service life. Maximum radial force is 950 N at 100 rpm for 10000 hours, derating to 650 N for 30000 hours — these limits apply with the force applied at mid-distance from the output shaft. The moment of inertia reflected to the input is 0.52 g.cm², which is low enough that it does not dominate the servo tuning for most small to medium motor loads. ## Temperature envelope and noise floor The noise level is 60 dB at 1 m under no-load — this is a moderate figure; in a quiet assembly cell it will be audible but not intrusive, while in a noisy production hall it will be masked by surrounding equipment.","metaTitle":"Schneider Electric GBX0800040842D planetary gearbox","metaDescription":"Schneider Electric GBX0800040842D planetary gearbox. 4:1 reduction, 115 N.m continuous torque, 96% efficiency, 60 dB noise.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Gear Reducers & Gearboxes"],"specifications":{"Efficiency":"96 %","Noise level":"60 dB at 1 m, no-load","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":"0.52 g.cm²","Mounting position":"Any position","Compatibility code":"GBX","Torsional rigidity":"6 N.m/arcmin","Maximum output torque":"184 N.m","Service life in hours":"30000 h at 100 rpm at 30 °C","Additional information":"Lubricated for life","Maximum axial force Fa":"1200 N at 100 rpm, during 10000 hour at 30°C 900 N at 100 rpm, during 30000 hour at 30°C","IP degree of protection":"Shaft output: IP54","Maximum radial force Fr":"650 N at 100 rpm, force applied at mid-distance from output shaft during 30000 hour at 30 °C 950 N at 100 rpm, force applied at mid-distance from output shaft during 10000 hour at 30 °C","Continuous output torque":"115 N.m","Gearbox external diameter":"80 mm","Product or component type":"Planetary gearbox","Maximum torsional backlash":"12 arc.min","Ambient Temperature For Operation":"-25...90 °C"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/11cb871f228577fcecdb1d8ac70cfa1b.pdf","sourceUrl":"https://www.se.com/ie/en/product/GBX0800040842D/gearbox-with-straight-teeth-gbx-ø-80-mm-reduction-41-12arcmin-115-n-m/","alternativesUrl":"https://aoctrl.com/api/mcp/products/GBX0800040842D/alternatives.json"},"ai":{"faq":[{"question":"What is the continuous torque rating of the GBX0800040842D?","answer":"The continuous output torque is 115 N.m, with a maximum peak torque of 184 N.m.
