It delivers a continuous output torque of 155 N.m at 100 rpm and a maximum output torque of 248 N.m under the same conditions — the continuous figure is the one to size against for steady-state duty cycles. Rated efficiency is 94 %, meaning about 6 % of input power is lost as heat in the gear mesh and bearings. For a servo or stepper motor application, that heat stays inside the housing — the lubricated-for-life grease handles it without a maintenance interval. Torsional rigidity is 12 N.m/arcmin, and maximum torsional backlash is 8 arc.min. In a positioning axis, the 8 arc.min of lost motion at reversal is the figure to budget into the overall system accuracy — the rigidity number governs how much windup you get under load before the output shaft moves. ## Load ratings and service life Service life is 30000 hours at 100 rpm and 30 °C ambient — that is about 3.4 years of continuous running. The axial and radial force limits are given at two life points: 2100 N axial and 1500 N radial for the full 30000-hour life, or 2800 N axial and 2000 N radial if you accept a 10000-hour life. These forces are applied at mid-distance from the output shaft; a longer overhung load reduces the allowable radial force. The shaft output carries an IP54 degree of protection — sealed against dust ingress and splashing water, but not submersion. The housing itself is not separately rated; the IP54 applies to the shaft exit seal. Ambient operating range is -25 to 90 °C, which covers most indoor industrial enclosures and unheated warehouses. Noise level is 65 dB at 1 m, no-load — this is the gear mesh whine under no torque. Under load the noise will rise slightly with the tooth contact stress, but the straight-tooth design is inherently noisier than helical at the same reduction. For a noise-sensitive installation (cleanroom, lab, packaging near operators), factor in an enclosure or acoustic damping. ## Sourcing reality — obsolete, quoted to order Schneider Electric lists the GBX1200040553F as obsolete. The part is available through independent surplus and broker channels — quantities are lot-specific and confirmed at RFQ. The shaft material is C45 steel, and the housing is black anodized aluminium. The gearbox external diameter is 120 mm. These dimensions and the 4:1 reduction ratio are the critical fit parameters for replacing an existing unit in a motion-control axis — confirm the mounting flange pattern and shaft keyway dimensions against the original before committing.","metaTitle":"Schneider Electric GBX1200040553F Planetary Gearbox, 4:1","metaDescription":"Schneider Electric GBX1200040553F planetary gearbox, 4:1 reduction, 155 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":"4:1","lifecycle_stage":"current","Housing material":"Black anodized aluminium","Device short name":"GBX","Compatibility code":"GBX","Torsional rigidity":"12 N.m/arcmin","Maximum output torque":"2195.0 lbf.in (248 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":"1371.9 lbf.in (155 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":"8 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/ebc10af0b984158ca77c20f8ad9693f2.pdf","sourceUrl":"https://www.se.com/ie/en/product/GBX1200040553F/gearbox-with-straight-teeth-gbx-ø-120-mm-reduction-41-8arcmin-155-n-m/","alternativesUrl":"https://aoctrl.com/api/mcp/products/GBX1200040553F/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/GBX1200040553F","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/GBX1200040553F when reusing this data.
