The continuous output torque is 85 N.m, with a maximum intermittent rating of 136 N.m — the continuous figure governs the duty cycle in a servo or stepper application; the peak number covers acceleration and emergency stops. Efficiency is listed at 96 %, which means about 4 % of the input power is lost as heat in the gear mesh and bearings. For a 1 kW motor, that's 40 W of thermal load the housing must dissipate — the black anodised aluminium body handles that in free air up to 90 °C ambient, but a confined panel or high-duty cycle may need forced ventilation. Noise level is 60 dB at 1 m, no-load — that's roughly the sound of a quiet office printer. Under load the straight-tooth mesh will be louder than helical; if acoustic constraints are tight, a helical or spiral-bevel box would be quieter, but this part's straight teeth give lower backlash and higher stiffness for positioning. ## Mechanical limits — shaft loads, backlash, and service life Maximum torsional backlash is 12 arc.min — that's the lost motion at the output shaft when reversing direction. For a pick-and-place or indexing axis, this sets the repeatability floor; a 12 arc.min gap at the output translates to about 0.14 mm of linear error on a 100 mm lever arm. If the application needs tighter positioning, a low-backlash or zero-backlash gearbox would be needed. Radial and axial force limits are given at two service-life points. At 100 rpm and 30 °C, the maximum radial force Fr is 650 N for a 30,000-hour life, or 950 N for a 10,000-hour life. Axial force Fa is 900 N at 30,000 hours, 1200 N at 10,000 hours. These are forces applied at mid-distance from the output shaft — a belt drive or overhung load that shifts the force closer to the bearing will reduce the allowable load. Service life is rated at 30,000 hours at 100 rpm and 30 °C. The gearbox is lubricated for life — no oil changes or regreasing intervals. The IP54 rating at the shaft output means it's protected against dust ingress and splashing water, but not against hose-down or immersion; the seal at the output shaft is the wet-end barrier. ## Obsolete — sourcing through independent channels Schneider Electric lists this gearbox as obsolete. The part is available through independent surplus and broker channels — quantities are lot-specific and confirmed at RFQ. No pin-compatible direct replacement exists from Schneider; a functional replacement would require checking the mounting flange, shaft diameter, and ratio against a current GBX or BSH series box. For volume or scheduled requirements, we can source against a blanket order.","metaTitle":"Schneider GBX0800030842D Planetary Gearbox, 3:1, 85 N.m","metaDescription":"Schneider Electric GBX0800030842D planetary gearbox, 3:1 ratio, 85 N.m continuous torque, 96% efficiency.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","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":"3:1","lifecycle_stage":"current","Housing material":"Black anodized aluminium","Device short name":"GBX","Moment Of Inertia":"0.77 g.cm²","Mounting position":"Any position","Compatibility code":"GBX","Torsional rigidity":"6 N.m/arcmin","Maximum output torque":"136 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":"85 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/6db563bd4a6d2663b716d2a137de9c6c.pdf","sourceUrl":"https://www.se.com/nl/en/product/GBX0800030842D/gearbox-with-straight-teeth-gbx-ø-80-mm-reduction-31-12arcmin-85-n-m/","alternativesUrl":"https://aoctrl.com/api/mcp/products/GBX0800030842D/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/GBX0800030842D","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/GBX0800030842D when reusing this data.
