It delivers 120 N·m (1062 lbf·in) continuous output torque at 100 rpm and 30 °C, with a maximum intermittent torque of 192 N·m (1699 lbf·in) under the same conditions. Rated torsional backlash is 14 arc-minutes — acceptable for general positioning but not for high-precision servo applications where sub-arc-min backlash is required. ## Efficiency, noise, and service life Efficiency is listed at 94%, meaning 6% of input power is lost as heat through the gear mesh and bearings. At 120 N·m output, the thermal loss is about 48 W — this gearbox runs warm but does not need external cooling in most duty cycles. Noise level is 60 dB at 1 m under no-load conditions — roughly the level of a quiet office conversation. Under load the noise will rise, but the straight-tooth design is inherently noisier than helical gearing at higher speeds. Service life is rated 30,000 hours at 100 rpm and 30 °C. The gearbox is lubricated for life, so no maintenance oil changes are needed over that interval. ## Mounting, shaft loads, and environmental limits Shaft output seal is rated IP54 — splash-proof but not submersible. The housing is black anodized aluminium; the output shaft is C45 carbon steel. Maximum axial force on the output shaft is 1200 N for a 10,000-hour life at 30 °C, derated to 900 N for the full 30,000-hour service life. Maximum radial force (mid-span on the shaft) is 950 N for 10,000 hours, 650 N for 30,000 hours. This covers most indoor industrial environments but not freezer or high-temp oven applications.","metaTitle":"Schneider GBX0800321402F Planetary Gearbox, 32:1, 120 N·m","metaDescription":"Obsolete Schneider GBX0800321402F planetary gearbox, 80 mm, 32:1 ratio, 120 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":"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/395027b767860dc73f4879047fa5592a.pdf","sourceUrl":"https://www.se.com/uk/en/product/GBX0800321402F/gearbox-with-straight-teeth-gbx-ø-80-mm-reduction-321-14arcmin-120-n-m/","alternativesUrl":"https://aoctrl.com/api/mcp/products/GBX0800321402F/alternatives.json"},"ai":{"faq":[{"question":"What is the continuous torque rating of the GBX0800321402F?","answer":"120 N·m (1062 lbf·in) at 100 rpm and 30 °C ambient.
