The continuous output torque is 260 N.m at 100 rpm and 30 °C, with a maximum intermittent torque of 416 N.m at the same speed — the ceiling before mechanical overload. Efficiency is listed at 94 %, which is typical for a single-stage planetary set with straight teeth — the remaining 6 % is heat dissipated in the gear mesh and bearings. The 30000-hour service life at rated load (100 rpm, 30 °C) assumes the input speed and torque stay within the continuous envelope; exceeding the maximum axial force of 2100 N or radial force of 1500 N at the output shaft will shorten that life. Maximum torsional backlash is 12 arcmin — this defines the lost motion between input and output when reversing direction. For positioning applications that need better than 0.2° repeatability, a lower-backlash gearbox (e.g. a precision planetary with 3-5 arcmin) would be a tighter fit. ## Sourcing a discontinued planetary gearbox This unit is sourced through independent surplus and overstock channels. Availability is lot-specific; quantities and condition (typically new-in-box, sealed) are confirmed at RFQ. The lubricated-for-life design means no oil-change schedule to verify on a stored unit — the grease charge is sealed for the service life. For a BOM that needs a drop-in replacement, the 120 mm diameter, 32:1 ratio, and 260 N.m continuous torque are the binding dimensions — any substitute must match the output shaft interface and mounting flange pattern. No pin-compatible alternative from the same family is documented. ## Installation constraints — IP54, shaft loads, and ambient range Shaft output protection is IP54 — the gearbox body is sealed against dust ingress and splashing water at the output shaft, but not submersion or high-pressure washdown. The housing is black anodized aluminium; the shaft is C45 carbon steel. Maximum axial force on the output shaft is 2100 N for the full 30000-hour life, or 2800 N if you accept a 10000-hour service interval. Radial force limits are 1500 N (30000 h) and 2000 N (10000 h), measured at mid-span on the output shaft at 100 rpm. Overhung loads from a belt drive or pinion must stay within these envelopes to avoid bearing fatigue. Ambient operating range is -25 to 90 °C — the grease and seals handle the cold end; the upper limit keeps the internal temperature below the lubricant degradation point. Noise at 1 m, no-load, is 65 dB — a moderate level for a planetary gearbox of this size.","metaTitle":"Schneider GBX1200320704F Planetary Gearbox, 32:1 Ratio","metaDescription":"Schneider Electric GBX1200320704F planetary gearbox, 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/f8ff29e8edb9865b72b2b5c19eab456f.pdf","sourceUrl":"https://www.se.com/ie/en/product/GBX1200320704F/gearbox-with-straight-teeth-gbx-ø-120-mm-reduction-321-12arcmin-260-n-m/","alternativesUrl":"https://aoctrl.com/api/mcp/products/GBX1200320704F/alternatives.json"},"ai":{"faq":[{"question":"What is the continuous torque rating of the GBX1200320704F?","answer":"Continuous output torque is 260 N.m at 100 rpm and 30 °C.
