The 25:1 reduction ratio delivers 110 N.m continuous output torque at 100 rpm (30 °C), with a maximum intermittent torque of 176 N.m for short-duration overloads. Torsional rigidity is 6.5 N.m/arcmin, and maximum backlash is 14 arcmin — figures that matter for positioning accuracy in indexing or pick-and-place axes. The shaft output carries an IP54 seal, adequate for splash exposure in a clean or lightly dusty environment. ## Load ratings and service life Rated service life is 30 000 hours at 100 rpm and 30 °C. At that same speed and temperature, the maximum axial force (Fa) is 900 N for 30 000 hours or 1200 N for 10 000 hours; maximum radial force (Fr) applied at mid-distance on the output shaft is 650 N for 30 000 hours or 950 N for 10 000 hours. These are the numbers to check against the actual overhung load and thrust from the driven mechanism. Efficiency is listed at 94 %, and the gearbox is lubricated for life — no maintenance schedule for oil changes. Noise level is 60 dB at 1 m, no-load, which is quiet enough for most production-floor environments without an enclosure. The housing is black anodised aluminium; the output shaft is C45 carbon steel. Ambient operating range is -25 to 90 °C. ## Sourcing — obsolete, quoted to order Schneider Electric lists the GBX0800250551F as obsolete. For a legacy install that needs this exact gearbox — same 80 mm frame, 25:1 ratio, and 14 arcmin backlash — the only channel is independent surplus or broker stock.","metaTitle":"Schneider Electric GBX0800250551F planetary gearbox, 25:1","metaDescription":"Schneider Electric GBX0800250551F planetary gearbox, 25:1 ratio, 110 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":"25:1","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":"1557.7 lbf.in (176 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":"973.6 lbf.in (110 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/deb38f48cf04754a13e4d55fb325ace3.pdf","sourceUrl":"https://www.se.com/ca/en/product/GBX0800250551F/gearbox-with-straight-teeth-gbx-ø-80-mm-reduction-251-14arcmin-110-n-m/","alternativesUrl":"https://aoctrl.com/api/mcp/products/GBX0800250551F/alternatives.json"},"ai":{"faq":[{"question":"What is the continuous output torque of the GBX0800250551F?","answer":"The continuous output torque is 110 N.m (973.6 lbf.in) at 100 rpm and 30 °C.
