It delivers 120 N.m continuous output torque at 100 rpm, with a maximum of 192 N.m before mechanical limits are reached. The 94% efficiency means about 6% of input power is lost as heat inside the housing — for a 120 N.m output at 100 rpm (roughly 1.26 kW mechanical), that's about 75 W of heat to manage. The black anodized aluminium housing sheds that passively in most panel-mount or machine-frame installations. With 14 arcmin maximum torsional backlash and 6.5 N.m/arcmin torsional rigidity, this gearbox sits in the precision class for indexing and positioning applications — not servo-grade (sub-arcmin), but tight enough for most pick-and-place, rotary indexing, and conveyor positioning where the load doesn't reverse direction rapidly. ## Load ratings and service life — sizing the gearbox for the duty cycle The continuous torque rating of 120 N.m at 100 rpm and 30 °C ambient gives a 30000-hour service life. Push it to 192 N.m maximum torque and the life drops — the axial and radial force ratings are also time-dependent: 1200 N axial for 10000 hours, 900 N for 30000 hours at 100 rpm. Radial load capacity at the output shaft is 650 N at mid-span for 30000 hours, or 950 N for 10000 hours. If you're driving a belt or chain, that side-load eats into the torque capacity — the combined load must stay inside the envelope. The shaft output seal is rated IP54, so it handles dust and splashing water but not washdown or submersion. The C45 steel output shaft is standard for this class — hard enough for keyed or clamped couplings, but not case-hardened for extreme wear environments. Noise level is 60 dB at 1 m no-load, which is typical for straight-tooth planetary gears; helical gears would be quieter but cost more. ## Obsolete — sourcing through independent distribution The GBX0800321403F is marked obsolete by Schneider Electric. For a line-down replacement or BOM fill, the part is sourced through independent surplus and new-old-stock channels. If you're planning a machine build and need a current-production alternative, the closest functional match would be another planetary gearbox in the same 80 mm frame size with 32:1 ratio and 120 N.m continuous torque — but the mounting flange, input shaft dimensions, and keyway must be verified against your motor and load interface.","metaTitle":"Schneider GBX0800321403F planetary gearbox, 32:1, 120 N.m","metaDescription":"Schneider Electric GBX0800321403F planetary gearbox, 80 mm, 32:1 ratio, 120 N.m continuous torque, 94% efficiency, 14 arcmin backlash.","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":"32:1","lifecycle_stage":"current","Housing material":"Black anodized aluminium","Device short name":"GBX","Compatibility code":"GBX","Torsional rigidity":"6.5 N.m/arcmin","Maximum output torque":"1699.3 lbf.in (192 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":"1062.09 lbf.in (120 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":"14 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/7aaccace4d2215eaabbc1d51ce2f523c.pdf","sourceUrl":"https://www.se.com/ca/en/product/GBX0800321403F/gearbox-with-straight-teeth-gbx-ø-80-mm-reduction-321-14arcmin-120-n-m/","alternativesUrl":"https://aoctrl.com/api/mcp/products/GBX0800321403F/alternatives.json"},"ai":{"faq":[{"question":"What is GBX0800321403F's continuous torque rating and service life?","answer":"Continuous output torque is 120 N.m at 100 rpm and 30 °C, with a rated service life of 30000 hours under those conditions.
