This is the compact frame size in the family, sized for servo or stepper motor output stages where envelope matters. Continuous output torque is 115 N.m at 100 rpm and 30 °C — this is the rating for sustained duty. The maximum output torque of 184 N.m at the same speed and temperature covers acceleration peaks and occasional overloads, but the continuous figure governs the thermal steady-state selection. Efficiency is listed at 94 %, which means 6 % of the input power is lost as heat inside the gearbox. For a 115 N.m continuous load at 100 rpm (roughly 1.2 kW mechanical output), the heat rejection is about 77 W — enough to raise the housing temperature above ambient but well within the aluminium housing's dissipation capacity at the rated operating range of -25 to 90 °C. ## Backlash, service life, and load limits — the fit constraints Maximum torsional backlash is 9 arc.min. For positioning applications, this is the lost motion at the output shaft when reversing direction — a standard-precision grade for general indexing and conveying, not for sub-arcminute positioning stages. Service life is 30000 hours at 100 rpm and 30 °C, lubricated for life with no maintenance interval. The gearbox is sealed — no oil changes or regreasing. The IP54 rating on the shaft output means the seal keeps out dust and splashing water, but the gearbox is not rated for washdown or submersion. Maximum axial force (Fa) is 1200 N at 100 rpm for a 10000-hour life, derating to 900 N for the full 30000-hour target. Maximum radial force (Fr) at mid-shaft is 950 N for 10000 hours, derating to 650 N for 30000 hours. These are the bearing load limits — overshoot them and the service life shortens faster than the linear derating suggests. ## Obsolete — sourcing through independent channels Schneider Electric lists the GBX0800041403F as obsolete. The gearbox is available through independent distribution and surplus channels. Quantities are lot-specific — confirmed at RFQ against the BOM line. For a replacement evaluation, the critical fit parameters are the 80 mm housing diameter, the 4:1 ratio, the 115 N.m continuous torque, and the 9 arc.min backlash class. Any substitute must match the input shaft interface and mounting pattern — these are not documented in the spec record and must be verified against the existing installation.","metaTitle":"Schneider Electric GBX0800041403F Planetary Gearbox, 4:1","metaDescription":"Schneider Electric GBX0800041403F planetary gearbox, 80 mm diameter, 4:1 reduction, 115 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":"60 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":"6 N.m/arcmin","Maximum output torque":"1628.5 lbf.in (184 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":"1200 N 100 rpm, during 10000 hour at 30°C 900 N 100 rpm, during 30000 hour at 30°C","IP Degree of Protection":"Shaft output IP54","Maximum radial force Fr":"650 N 100 rpm, force applied at mid-distance from output shaft during 30000 hour at 30 °C 950 N 100 rpm, force applied at mid-distance from output shaft during 10000 hour at 30 °C","Continuous output torque":"1017.8 lbf.in (115 N.m) 100 rpm 86 °F (30 °C)","Gearbox external diameter":"3.1 in (80 mm)","Product or Component Type":"Planetary gearbox","Maximum torsional backlash":"9 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/45d0474dff3e2b3c766c0692a1fc4f97.pdf","sourceUrl":"https://www.se.com/nz/en/product/GBX0800041403F/gearbox-with-straight-teeth-gbx-ø-80-mm-reduction-41-9arcmin-115-n-m/","alternativesUrl":"https://aoctrl.com/api/mcp/products/GBX0800041403F/alternatives.json"},"ai":{"faq":[{"question":"What is the continuous torque rating of the GBX0800041403F?","answer":"Continuous output torque is 115 N.m (1017.8 lbf.in) at 100 rpm and 30 °C.
