Planetary construction packs higher torque density into the same envelope compared to parallel-shaft reducers — the load is shared across multiple planet gears, which also lowers the noise floor to 65 dB at 1 m under no-load conditions. Continuous output torque is 1858.7 lbf.in (210 N.m) at 100 rpm and 30 °C, with a maximum intermittent rating of 2973.8 lbf.in (336 N.m) under the same conditions. The 9:1 ratio means the input motor sees roughly one-ninth of that output torque reflected back — a 2.3 N.m motor-side torque for the 210 N.m continuous case, before accounting for the 94 % mechanical efficiency. Torsional backlash is capped at 12 arcmin, and torsional rigidity is 13 N.m/arcmin. For a positioning axis, that backlash figure sets the repeatability floor — a 12 arcmin windup at the output translates to about 0.35 mm of linear play on a 100 mm lever arm, which matters for pick-and-place or indexing applications where the load reverses direction. ## Load limits and service life — the mechanical boundary conditions Rated service life is 30000 hours at 100 rpm and 30 °C, with the gearbox lubricated for life — no re-greasing interval to schedule. The shaft output seal carries an IP54 rating, meaning it resists dust ingress and splashing water but is not rated for pressurized washdown or submersion. Maximum axial force (Fa) on the output shaft is 2100 N at 100 rpm for the full 30000-hour life, or 2800 N if you accept a 10000-hour service window. Radial force (Fr) applied at mid-distance on the output shaft is 1500 N for 30000 hours, 2000 N for 10000 hours. These are the limits that govern overhung loads from belt drives or chain sprockets — exceed them and the output bearing life drops faster than the hour rating suggests. The housing is black anodized aluminium, the shaft is C45 steel — standard for this torque class. ## Obsolete — sourcing through independent channels Schneider Electric has marked the GBX1200090553F as obsolete. The part is available through independent surplus and broker channels — quantities are lot-specific and confirmed at RFQ. No pin-compatible or dimensionally identical direct replacement is listed by Schneider, so a BOM substitution would require a full mechanical re-evaluation of the mounting interface, shaft keyway, and load ratings. The 94 % efficiency figure and 210 N.m continuous rating remain the reference points for any replacement candidate — a substitute must match or exceed those at the same 120 mm housing diameter and 9:1 ratio to drop in without re-engineering the axis.","metaTitle":"Schneider Electric GBX1200090553F Planetary Gearbox","metaDescription":"Schneider Electric GBX1200090553F planetary gearbox, 9:1 reduction, 210 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":"9:1","lifecycle_stage":"current","Housing material":"Black anodized aluminium","Device short name":"GBX","Compatibility code":"GBX","Torsional rigidity":"13 N.m/arcmin","Maximum output torque":"2973.8 lbf.in (336 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":"1858.7 lbf.in (210 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/f0e2a50fe97dd6b9cad0afb989717f64.pdf","sourceUrl":"https://www.se.com/uk/en/product/GBX1200090553F/gearbox-with-straight-teeth-gbx-ø-120-mm-reduction-91-12arcmin-210-n-m/","alternativesUrl":"https://aoctrl.com/api/mcp/products/GBX1200090553F/alternatives.json"},"ai":{"faq":[{"question":"What is GBX1200090553F's continuous torque rating?","answer":"Continuous output torque is 1858.7 lbf.in (210 N.m) at 100 rpm and 30 °C.
