Planetary construction packs higher torque density than a parallel-shaft reducer of the same envelope — the load is shared across multiple planet gears. Continuous output torque is 50 N.m at 100 rpm and 30 °C ambient; maximum intermittent torque reaches 80 N.m under the same conditions. The 94 % efficiency means roughly 6 % of the input power is lost as heat — negligible for sizing the motor but relevant if the gearbox is enclosed in a small cabinet without airflow. Backlash is 9 arc.min maximum — a standard-precision grade suitable for indexing tables, conveyor drives, and general positioning where the load doesn't reverse direction under high frequency. For a servo axis requiring less than 5 arc.min, this unit would need a preloaded or low-backlash variant from the same family. ## Load limits and service life — the numbers that govern the replacement interval Rated service life is 30,000 hours at 100 rpm and 30 °C — that's about 3.4 years of continuous 24/7 operation. The gearbox is lubricated for life, so no re-greasing schedule; when the grease degrades past the 30,000-hour mark, the unit is replaced, not serviced. Maximum axial force on the output shaft is 1200 N for a 10,000-hour life target, derated to 900 N if you need the full 30,000 hours. Radial force at mid-span on the output shaft is 650 N for 30,000 hours, 950 N for 10,000 hours — these are the bearing limits, not the shaft bending strength, so an overhung load like a belt pulley needs a separate outboard bearing support. Torsional rigidity is 6 N.m per arcmin — meaning a steady 50 N.m load twists the output shaft about 8.3 arcmin before the gear teeth deflection is added. For a positioning axis, this stiffness plus the 9 arc.min backlash sets the total lost motion at roughly 17 arc.min under full continuous load. ## Obsolete — sourcing reality and what replaces it Schneider Electric lists the GBX0800081403F as obsolete. BPH, BSH) that use different mounting interfaces and shaft dimensions. No pin-compatible drop-in replacement exists from Schneider's current catalog — a mechanical re-design of the mounting bracket and coupling will be required to use a modern equivalent. The IP54 rating on the shaft output means the gearbox is splash-proof from the output side but not sealed for washdown — suitable for dry indoor environments like conveyor drives in a warehouse or packaging line, not for food-processing zones with high-pressure cleaning.","metaTitle":"Schneider Electric GBX0800081403F Planetary Gearbox, 8:1","metaDescription":"Schneider Electric GBX0800081403F planetary gearbox, 8:1 ratio, 50 N.m continuous torque, 94% efficiency, 9 arc.min 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":"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/3a8504513321dafbfac1db734d131275.pdf","sourceUrl":"https://www.se.com/us/en/product/GBX0800081403F/gearbox-with-straight-teeth-gbx-ø-80-mm-reduction-81-9arcmin-50-n-m/","alternativesUrl":"https://aoctrl.com/api/mcp/products/GBX0800081403F/alternatives.json"},"ai":{"faq":[{"question":"What is the closest replacement for GBX0800081403F in the Schneider GBX family?","answer":"No pin-compatible successor is published.
