Its 25:1 reduction ratio pairs with a continuous output torque of 230 N.m at 100 rpm and 30 °C, and a maximum output torque of 368 N.m under the same conditions. Efficiency is listed at 94 %, which is typical for a single-stage planetary of this ratio. The 65 dB noise level at 1 m, no-load is moderate — audible in a quiet machine shop but not intrusive on a production floor with background ambient noise. ## Mechanical limits that set the application envelope The gearbox carries a 30000-hour service life at 100 rpm and 30 °C, and is lubricated for life — no maintenance oil changes, but the life figure assumes clean, rated load conditions. Maximum axial force on the output shaft is 2100 N for the 30000-hour target, rising to 2800 N if you accept a 10000-hour life. Radial force limits follow the same pattern: 1500 N for 30000 hours, 2000 N for 10000 hours, with the force applied at mid-distance from the output shaft. Torsional rigidity is 13 N.m/arcmin, and maximum torsional backlash is 12 arc.min. For a positioning axis, the 12 arc.min backlash means the output shaft can rotate up to 0.2° before the load engages — acceptable for conveyor drives or indexing tables, but too loose for a servo positioning stage that needs single-arcminute repeatability. The housing is black anodized aluminium, the shaft is C 45 steel, and shaft output protection is IP54 — splash-resistant but not washdown-rated. ## Obsolete — sourcing through independent channels Schneider Electric lists the GBX1200251003F as obsolete. The part is available through independent surplus and broker channels — quantities are lot-specific, and availability is confirmed at RFQ time.","metaTitle":"Schneider Electric GBX1200251003F Planetary Gearbox, 25:1","metaDescription":"Schneider Electric GBX1200251003F planetary gearbox, 25:1 ratio, 230 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":"65 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":"13 N.m/arcmin","Maximum output torque":"3257.07 lbf.in (368 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":"2100 N 100 rpm, during 30000 hour at 30°C 2800 N 100 rpm, during 10000 hour at 30°C","IP Degree of Protection":"Shaft output IP54","Maximum radial force Fr":"1500 N 100 rpm, force applied at mid-distance from output shaft during 30000 hour at 30 °C 2000 N 100 rpm, force applied at mid-distance from output shaft during 10000 hour at 30 °C","Continuous output torque":"2035.7 lbf.in (230 N.m) 100 rpm 86 °F (30 °C)","Gearbox external diameter":"4.7 in (120 mm)","Product or Component Type":"Planetary gearbox","Maximum torsional backlash":"12 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/dc5044b8ec7f59520db6b22f354ea13c.pdf","sourceUrl":"https://www.se.com/ca/en/product/GBX1200251003F/gearbox-with-straight-teeth-gbx-ø-120-mm-reduction-251-12arcmin-230-n-m/","alternativesUrl":"https://aoctrl.com/api/mcp/products/GBX1200251003F/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/GBX1200251003F","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/schneider/GBX1200251003F when reusing this data.
