That 60% torque headroom above the continuous rating means it can handle transient overloads during acceleration or stall recovery without immediately tripping the upstream drive — provided the duty cycle stays within the 30000-hour service life envelope at 30 °C ambient. Efficiency sits at 94 %, which is typical for a single-stage planetary with straight-cut teeth at this ratio. The remaining 6 % is gear mesh and bearing loss, dissipated through the black anodised aluminium housing; at 230 N.m and 100 rpm the thermal loss is about 240 W, well within the housing's natural convection capacity at 30 °C ambient. ## Backlash and stiffness for positioning Maximum torsional backlash is 12 arcmin — that is the total lost motion across the gear train measured at the output shaft. For a 15:1 reducer, 12 arcmin at the output corresponds to roughly 0.8 arcmin at the input, which is acceptable for indexing or positioning applications that do not require zero-backlash servo-grade accuracy. The torsional rigidity of 13 N.m/arcmin means the output shaft deflects about 0.08° under full continuous torque — a stiffness figure that matters when the load has significant inertia and the drive is accelerating or decelerating through the gear train. The straight-tooth planetary design inherently produces more noise than helical gearing — the datasheet lists 65 dB at 1 m, no-load, which is audible but within typical industrial enclosure limits. In a quiet environment like a cleanroom or packaging line, the gearbox may need acoustic cladding or a sound-dampening enclosure to keep the floor noise below 70 dB. ## Sourcing reality — obsolete, but available Schneider Electric lists the GBX1200150553F as obsolete. The part is sourced through independent surplus and broker channels; quantities are lot-specific and confirmed at RFQ. No pin-compatible or footprint-equivalent replacement exists from Schneider — any substitution requires a mechanical re-design of the mounting interface and possibly the input/output shaft connections. For a BOM that already carries this gearbox, the 30000-hour service life at rated load means a unit installed today still has years of usable life remaining, but spares procurement should be treated as a last-time-buy decision. ## Mechanical interface and environmental limits The output shaft is C45 carbon steel, and the housing is black anodised aluminium. The shaft output seal carries IP54 protection — splash-resistant, not submersible, and not rated for washdown. In a dusty or wet environment, the gearbox should be mounted with the output shaft pointing downward or shielded from direct spray. Ambient operating range is -25 to 90 °C. The unit is lubricated for life — no oil changes or regreasing intervals. Maximum axial force on the output shaft is 2100 N for the full 30000-hour life, or 2800 N if the application accepts a shorter 10000-hour life. Maximum radial force is 1500 N at mid-span for 30000 hours, or 2000 N for 10000 hours. These are the limits that govern bearing life; exceeding them accelerates wear and reduces the service life below the datasheet figure.","metaTitle":"Schneider Electric GBX1200150553F Planetary Gearbox, 15:1","metaDescription":"Schneider Electric GBX1200150553F planetary gearbox, 15:1 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":"15:1","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/c0b8c839c6015c257770b2f3adc24e90.pdf","sourceUrl":"https://www.se.com/ca/en/product/GBX1200150553F/gearbox-with-straight-teeth-gbx-ø-120-mm-reduction-151-12arcmin-230-n-m/","alternativesUrl":"https://aoctrl.com/api/mcp/products/GBX1200150553F/alternatives.json"},"ai":{"faq":[{"question":"What is the continuous torque rating of the GBX1200150553F?","answer":"Continuous output torque is 230 N.m at 100 rpm and 30 °C ambient.
