Available through independent surplus and broker channels. Quantities are lot-specific and confirmed at RFQ — no stock-holding claim is made here. ## Torque ratings that define the fit Continuous output torque is 38 N.m at 100 rpm at 30 °C — this is the thermal steady-state limit for the gearbox in a servo or motion-control drivetrain. Maximum output torque is 61 N.m at 100 rpm at 30 °C, representing the peak overload capacity before mechanical damage. The 4:1 reduction ratio means the input torque is one-quarter of these output values, less efficiency losses. Service life is rated at 30000 hours at 100 rpm and 30 °C — a reliability floor for MRO planning in continuous-duty applications like conveyors or indexing tables. ## Mechanical stiffness and load capacity Torsional rigidity is 2.3 N.m/arcmin — this stiffness figure matters for positioning accuracy in servo applications where windup under load affects the encoder feedback loop. Maximum axial force Fa is 450 N at 100 rpm over 30000 hours, or 600 N over 10000 hours. Maximum radial force Fr is 340 N at 100 rpm over 30000 hours, or 500 N over 10000 hours, with force applied at mid-distance from the output shaft. These limits govern the bearing life when the gearbox drives an overhung load such as a pulley or sprocket. The shaft output seal is rated IP54, meaning protection against dust ingress and splashing water — suitable for indoor industrial environments but not washdown or outdoor exposure. ## Efficiency, noise, and environmental envelope Efficiency is listed at 96 % — this is the mechanical efficiency at rated load, meaning 4 % of input power is lost as heat. For a 38 N.m continuous output at 100 rpm (approximately 400 W output), the heat loss is roughly 16 W, which the black anodized aluminium housing dissipates without forced cooling. Noise level is 58 dB at 1 m, no-load — this is the acoustic emission from the straight-tooth planetary mesh without load. Under load the noise typically increases by 3–6 dB depending on the torque and speed. The gearbox is lubricated for life, so no relubrication interval needs to be scheduled — a maintenance-free advantage for hard-to-access installations. Moment of inertia is 0.093 g.cm² — this low reflected inertia is typical for a planetary gearbox of this frame size and is compatible with servo motor sizing without excessive acceleration torque penalties.","metaTitle":"Schneider Electric GBX0600040851G Planetary Gearbox, 4:1","metaDescription":"Schneider Electric GBX0600040851G planetary gearbox, 60 mm frame, 4:1 reduction, 38 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":"58 dB at 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","Moment Of Inertia":"0.093 g.cm²","Mounting position":"Any position","Compatibility code":"GBX","Torsional rigidity":"2.3 N.m/arcmin","Maximum output torque":"61 N.m at 100 rpm at 30 °C","Service life in hours":"30000 h at 100 rpm at 30 °C","Additional information":"Lubricated for life","Maximum axial force Fa":"450 N at 100 rpm, during 30000 hour at 30°C 600 N at 100 rpm, during 10000 hour at 30°C","IP degree of protection":"Shaft output: IP54","Maximum radial force Fr":"340 N at 100 rpm, force applied at mid-distance from output shaft during 30000 hour at 30 °C 500 N at 100 rpm, force applied at mid-distance from output shaft during 10000 hour at 30 °C","Continuous output torque":"38 N.m at 100 rpm at 30 °C","Gearbox external diameter":"60 mm","Product or component type":"Planetary gearbox","Maximum torsional backlash":"16 arc.min","Ambient Temperature For Operation":"-25...90 °C"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/f59bd171ad0d103cf5bf321b93c79ec1.pdf","sourceUrl":"https://www.se.com/sg/en/product/GBX0600040851G/gearbox-with-straight-teeth-gbx-ø-60-mm-reduction-41-16arcmin-38-n-m/","alternativesUrl":"https://aoctrl.com/api/mcp/products/GBX0600040851G/alternatives.json"},"ai":{"faq":[{"question":"What is the continuous output torque of GBX0600040851G?","answer":"The continuous output torque is 38 N.m at 100 rpm at 30 °C.
