The 3:1 reduction ratio sets the speed/torque tradeoff: input speed is three times output speed. Rated service life is 30,000 hours at 100 rpm and 30 °C — this is the L10 life under continuous rated load. If your duty cycle runs at higher speed or temperature, derate the life accordingly; the gearbox is lubricated for life, so no oil-change interval extends the service window. ## Mechanical limits — shaft loads and backlash Maximum axial force on the output shaft is 1200 N for a 10,000-hour life at 100 rpm and 30 °C, dropping to 900 N for the full 30,000-hour rating. Maximum radial force (applied at mid-shaft) is 950 N for 10,000 hours or 650 N for 30,000 hours. These are the bearing load limits — exceeding them shortens service life or causes premature failure. Maximum torsional backlash is 9 arc-minutes — this is the angular play between input and output under reversing load. For positioning applications (indexing, pick-and-place), this sets the repeatability floor; if your system needs tighter than 9 arc-min, this gearbox is not the fit. Torsional rigidity is 6 N.m/arcmin — the stiffness under load before windup. A higher number means less angular deflection per unit torque, which matters for servo-driven axes where the gearbox stiffness contributes to the overall system bandwidth. ## Efficiency, noise, and environmental fit Listed efficiency is 94 % — this is the power transmission efficiency at rated load and speed. For a 3:1 planetary stage, this is typical; the 6 % loss is mostly gear mesh friction and bearing drag, dissipated as heat within the black anodized aluminium housing. Noise level is 60 dB at 1 m, no-load — this is the acoustic emission from the straight-cut gear teeth under no-load spin. Under load, noise will increase; straight teeth are inherently noisier than helical, so if the gearbox runs in an operator-occupied area, factor in the sound level. Shaft output is rated IP54 — the housing seals against dust ingress and splashing water at the output shaft. The gearbox body itself is not fully sealed; the IP rating applies to the shaft exit point. Ambient operating range is -25 to 90 °C, covering most indoor industrial environments.","metaTitle":"Schneider Electric GBX0800031404F planetary gearbox, 3:1","metaDescription":"Schneider Electric GBX0800031404F planetary gearbox, 3:1 ratio, 85 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":"3:1","lifecycle_stage":"current","Housing material":"Black anodized aluminium","Device short name":"GBX","Compatibility code":"GBX","Torsional rigidity":"6 N.m/arcmin","Maximum output torque":"1203.7 lbf.in (136 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":"752.3 lbf.in (85 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/f360b5a69e1f61e5df93a57f7f3e9659.pdf","sourceUrl":"https://www.se.com/ca/en/product/GBX0800031404F/gearbox-with-straight-teeth-gbx-ø-80-mm-reduction-31-9arcmin-85-n-m/","alternativesUrl":"https://aoctrl.com/api/mcp/products/GBX0800031404F/alternatives.json"},"ai":{"faq":[{"question":"What is the continuous output torque of the GBX0800031404F?","answer":"85 N.m at 100 rpm and 30 °C.
