Service life is rated 30,000 hours at 100 rpm and 30 °C; the axial and radial force ratings at that life are 2100 N (Fa) and 1500 N (Fr) respectively, both measured at 100 rpm and mid-span on the output shaft. ## Accuracy and stiffness specs Maximum torsional backlash is 8 arc.min — this sets the positioning repeatability floor for the load side. Torsional rigidity is 12 N.m/arcmin, meaning each 12 N.m of torque twist the output shaft by one arc-minute. The straight-tooth planetary design delivers 96 % efficiency across the ratio, with a noise floor of 65 dB at 1 m under no-load conditions. ## Construction and integration Housing is black anodized aluminium, 120 mm external diameter; shaft material is C 45 steel. The gearbox is lubricated for life and can be mounted in any position. Shaft output seal is rated IP54 — suitable for dry indoor environments with dust and light splash exposure, but not for washdown or submerged service. Operating ambient temperature range spans -25 to 90 °C, covering most industrial enclosure conditions without active cooling. ## Lifecycle and sourcing Schneider Electric lists this part as obsolete. No official successor or cross-reference is recorded from the manufacturer. Available through independent surplus and broker channels; quantities are lot-specific and confirmed at RFQ. No pin-compatible or footprint-equivalent direct replacement is documented.","metaTitle":"Schneider GBX1200050844D Planetary Gearbox, 5:1, 195 N.m","metaDescription":"Schneider Electric GBX1200050844D planetary gearbox, 5:1 ratio, 195 N.m continuous torque, 96% efficiency.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Gear Reducers & Gearboxes"],"specifications":{"Efficiency":"96 %","Noise level":"65 dB at 1 m, no-load","Gear box type":"Straight teeth","Housing colour":"Black","Shaft material":"C 45","Reduction ratio":"5:1","lifecycle_stage":"current","Housing material":"Black anodized aluminium","Device short name":"GBX","Moment Of Inertia":"1.53 g.cm²","Mounting position":"Any position","Compatibility code":"GBX","Torsional rigidity":"12 N.m/arcmin","Maximum output torque":"312 N.m","Service life in hours":"30000 h at 100 rpm at 30 °C","Additional information":"Lubricated for life","Maximum axial force Fa":"2100 N at 100 rpm, during 30000 hour at 30°C 2800 N at 100 rpm, during 10000 hour at 30°C","IP degree of protection":"Shaft output: IP54","Maximum radial force Fr":"1500 N at 100 rpm, force applied at mid-distance from output shaft during 30000 hour at 30 °C 2000 N at 100 rpm, force applied at mid-distance from output shaft during 10000 hour at 30 °C","Continuous output torque":"195 N.m","Gearbox external diameter":"120 mm","Product or component type":"Planetary gearbox","Maximum torsional backlash":"8 arc.min","Ambient Temperature For Operation":"-25...90 °C"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/085ed660f645edd61a532c89820fa2cb.pdf","sourceUrl":"https://www.se.com/nl/en/product/GBX1200050844D/gearbox-with-straight-teeth-gbx-ø-120-mm-reduction-51-8arcmin-195-n-m/","alternativesUrl":"https://aoctrl.com/api/mcp/products/GBX1200050844D/alternatives.json"},"ai":{"faq":[{"question":"What is the continuous torque rating of GBX1200050844D?","answer":"195 N.m continuous output torque, with a maximum of 312 N.m for intermittent peak loads.
