The 50 N.m continuous output torque at 100 rpm and 30 °C is the sustained load the gearbox can carry in service — not a peak or intermittent figure, so it governs the duty cycle for conveyor, indexing, or positioning applications. Rated efficiency is 94 %, which means 6 % of the input power is lost as heat inside the housing. In a compact 80 mm aluminium body, that thermal budget is tight — the gearbox relies on the anodised surface for convection cooling, not an external fan. Maximum output torque is 80 N.m at 100 rpm and 30 °C, but that figure assumes a 30000-hour service life. For a 10000-hour design life at the same speed and temperature, the allowable axial and radial loads increase — 1200 N axial force vs 900 N, and 950 N radial force vs 650 N. The service life target drives the load limit, not the other way around. ## Backlash, noise, and environmental fit Maximum torsional backlash is 9 arcmin — this is the angular play between input and output when the direction reverses. For a positioning axis that indexes to a stop, 9 arcmin at the output translates to about 0.13 mm of linear error at a 50 mm radius arm. If the application needs tighter positioning, a lower-backlash gearbox (e.g. 3 arcmin) would be the correct class. Noise level is 60 dB at 1 m, no-load — a moderate figure for a straight-tooth planetary. In a quiet production area (55 dB ambient), the gearbox will be audible; in a typical machine hall (75 dB+), it will not stand out. The straight-tooth design is inherently noisier than helical, but the trade-off is lower cost and no axial thrust load on the bearings. Shaft output is IP54 — the seal at the output shaft keeps out dust and splashing water, but the gearbox is not rated for washdown or hose-down cleaning. The housing itself is sealed, but the input shaft and breather (if present) are the ingress points to watch. Ambient operating range is -25 to 90 °C, which covers most indoor industrial environments but not ovens or freezers without derating. ## Obsolete — sourcing through independent channels Schneider Electric lists the GBX0800081004F as obsolete. The gearbox is available through independent surplus and broker channels — quantities are lot-specific and confirmed at RFQ. The gearbox is lubricated for life — no re-greasing interval. The C45 steel shaft and black anodised aluminium housing are standard for this class; the shaft material is machinable for custom keyways or flats if the application requires it.","metaTitle":"Schneider Electric GBX0800081004F planetary gearbox","metaDescription":"Schneider Electric GBX0800081004F planetary gearbox, 8:1 reduction, 50 N.m continuous torque, 94% efficiency.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Gear Reducers & Gearboxes"],"specifications":{"Efficiency":"94 %","Noise level":"60 dB 1 m, no-load","Gear box type":"Straight teeth","Housing Colour":"Black","Shaft material":"C 45","Reduction ratio":"8:1","lifecycle_stage":"current","Housing material":"Black anodized aluminium","Device short name":"GBX","Compatibility code":"GBX","Torsional rigidity":"6 N.m/arcmin","Maximum output torque":"708.06 lbf.in (80 N.m) 100 rpm 86 °F (30 °C)","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":"1200 N 100 rpm, during 10000 hour at 30°C 900 N 100 rpm, during 30000 hour at 30°C","IP Degree of Protection":"Shaft output IP54","Maximum radial force Fr":"650 N 100 rpm, force applied at mid-distance from output shaft during 30000 hour at 30 °C 950 N 100 rpm, force applied at mid-distance from output shaft during 10000 hour at 30 °C","Continuous output torque":"442.5 lbf.in (50 N.m) 100 rpm 86 °F (30 °C)","Gearbox external diameter":"3.1 in (80 mm)","Product or Component Type":"Planetary gearbox","Maximum torsional backlash":"9 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/5bb6fae326de1e97efcc87aa5a044955.pdf","sourceUrl":"https://www.se.com/nz/en/product/GBX0800081004F/gearbox-with-straight-teeth-gbx-ø-80-mm-reduction-81-9arcmin-50-n-m/","alternativesUrl":"https://aoctrl.com/api/mcp/products/GBX0800081004F/alternatives.json"},"ai":{"faq":[{"question":"What is the continuous output torque of GBX0800081004F?","answer":"50 N.m (442.5 lbf.in) at 100 rpm and 30 °C.
