Efficiency is listed at 94 %, which is typical for a single-stage planetary with straight teeth. The 6 % loss shows up as heat in the housing — the black anodized aluminium body (120 mm diameter) acts as the heat sink, so mounting orientation and airflow matter if the duty cycle is high. ## Load limits and service life Rated service life is 30,000 hours at 100 rpm and 30 °C — that is the L10 bearing life under the rated radial and axial loads. The maximum radial force Fr is 1500 N applied at mid-span on the output shaft for the full 30,000-hour life; it can handle 2000 N if you accept a 10,000-hour life. Maximum axial force Fa follows the same pattern: 2100 N for 30,000 hours, 2800 N for 10,000 hours. Torsional rigidity is 12 N.m/arcmin — this tells you how many arc-minutes the output shaft twists per N.m of applied torque. Combined with the maximum torsional backlash of 8 arc.min, it defines the positioning repeatability for a pick-and-place or indexing axis. Straight teeth inherently have more backlash than helical, so if zero-backlash is required this is not the gearbox for that application. ## Lifecycle reality — obsolete, sourced through surplus Schneider Electric lists the GBX1200030553F as obsolete. This part is available through independent surplus and broker channels — quantities are lot-specific and confirmed at RFQ. The 30,000-hour service life means a unit sourced today could still cover a decade of single-shift operation, but once the surplus stock is gone there is no factory replenishment. The gearbox is lubricated for life — no oil-change schedule, which simplifies maintenance but also means the lubricant condition is the wear limit. Shaft output IP54 keeps dust and splash out of the output seal, but the motor-side input is not separately rated — the motor itself provides the primary seal at that interface.","metaTitle":"Schneider Electric GBX1200030553F Planetary Gearbox, 3:1","metaDescription":"Schneider Electric GBX1200030553F planetary gearbox, 3:1 ratio, 115 N.m continuous torque, 94% efficiency, IP54 shaft output.","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":"3:1","lifecycle_stage":"current","Housing material":"Black anodized aluminium","Device short name":"GBX","Compatibility code":"GBX","Torsional rigidity":"12 N.m/arcmin","Maximum output torque":"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":"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":"1017.8 lbf.in (115 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/e88ff93ff43819314ad9ac3636ae0764.pdf","sourceUrl":"https://www.se.com/nz/en/product/GBX1200030553F/gearbox-with-straight-teeth-gbx-ø-120-mm-reduction-31-8arcmin-115-n-m/","alternativesUrl":"https://aoctrl.com/api/mcp/products/GBX1200030553F/alternatives.json"},"ai":{"faq":[{"question":"What is the continuous torque rating of GBX1200030553F?","answer":"115 N.m continuous at 100 rpm and 30 °C.
