This gearbox is sourced through independent surplus and broker channels — quantities are lot-specific, confirmed at RFQ. Do not plan a new BOM around it without verifying availability first. ## Torque ratings and what they mean for the load The continuous output torque is 260 N.m at 100 rpm and 30 °C ambient. This is the rating that governs steady-state duty — sizing the gearbox so the driven load stays below this figure avoids premature wear. The maximum output torque is 416 N.m under the same conditions, which covers peak overloads during starting or momentary jams. The 32:1 reduction ratio means input speed is divided by 32; match the motor's rated speed to the required output speed with this ratio. ## Service life, backlash, and mechanical limits Rated service life is 30,000 hours at 100 rpm and 30 °C. The gearbox is lubricated for life — no scheduled grease change. Maximum torsional backlash is 12 arc.min, which sets the positioning repeatability floor for indexing or servo-follower applications. Torsional rigidity is 13 N.m/arcmin — wind-up under load is predictable and linear within the elastic range. Maximum axial force on the output shaft is 2100 N for the 30,000-hour life target, or 2800 N if the application accepts a 10,000-hour service life. Maximum radial force is 1500 N at 30,000 hours, 2000 N at 10,000 hours, with the force applied at mid-distance from the output shaft. These limits govern belt-drive overhung loads and direct-coupling axial thrust. ## Efficiency, noise, and environmental fit Efficiency is listed at 94 % — the 6 % loss is thermal, so the housing must dissipate about 6 % of the transmitted power. Noise level is 65 dB at 1 m, no-load, which is typical for a straight-tooth planetary stage. The housing is black anodized aluminium with a 120 mm external diameter. Shaft output is rated IP54 — splash-resistant at the seal face but not submersible. Ambient operating range is -25 to 90 °C. Shaft material is C 45 carbon steel.","metaTitle":"Schneider Electric GBX1200320553F Planetary Gearbox, 32:1","metaDescription":"Schneider Electric GBX1200320553F planetary gearbox, 120 mm diameter, 32:1 reduction, 260 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":"32:1","lifecycle_stage":"current","Housing material":"Black anodized aluminium","Device short name":"GBX","Compatibility code":"GBX","Torsional rigidity":"13 N.m/arcmin","Maximum output torque":"3681.9 lbf.in (416 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":"2301.2 lbf.in (260 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/dd603d56b648c257d0b608a0df34733d.pdf","sourceUrl":"https://www.se.com/ie/en/product/GBX1200320553F/gearbox-with-straight-teeth-gbx-ø-120-mm-reduction-321-12arcmin-260-n-m/","alternativesUrl":"https://aoctrl.com/api/mcp/products/GBX1200320553F/alternatives.json"},"ai":{"faq":[{"question":"What is the continuous output torque of GBX1200320553F?","answer":"The continuous output torque is 260 N.m at 100 rpm and 30 °C ambient.
