That continuous rating is the figure to size against the driven load's running torque — the 70 N.m maximum output torque (at the same speed and temperature) covers intermittent peaks like acceleration or momentary overloads, not sustained duty. Efficiency is listed at 94 %, which means about 6 % of input power is lost as heat inside the gearbox. For a motor driving this gearbox at, say, 500 W input, the heat rejection is roughly 30 W — negligible in free air but worth considering if the gearbox is enclosed or mounted near temperature-sensitive components. ## Mechanical limits — shaft loads and service life The output shaft is C 45 steel and carries defined overhung load limits: maximum axial force Fa is 450 N for a 30,000-hour life at 100 rpm, or 600 N if you accept a shorter 10,000-hour life. Radial force Fr at mid-shaft is 340 N for the longer life, 500 N for the shorter. These are the limits for belt-pulley or chain-sprocket loads applied to the shaft — exceeding them shortens bearing life faster than the torque rating would suggest. Torsional rigidity is 2.5 N.m/arcmin — a measure of how much the output shaft twists under load. For positioning applications, the 20 arcmin maximum torsional backlash is the angular play between input and output when direction reverses; this matters for indexing or servo-driven axes where repeatability is critical. ## Lifecycle reality — obsolete, sourced to order Schneider Electric lists the GBX0600121403F as obsolete. The gearbox is lubricated for life and sealed to IP54 at the shaft output — the seal protects the bearing from dust and splash, but the housing itself is not rated for washdown. Ambient operating range is -25 to 90 °C, which covers most indoor industrial environments.","metaTitle":"Schneider Electric GBX0600121403F Planetary Gearbox, 12:1","metaDescription":"Schneider Electric GBX0600121403F planetary gearbox, 60 mm diameter, 12:1 reduction, 44 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":"58 dB 1 m, no-load","Gear box type":"Straight teeth","Housing Colour":"Black","Shaft material":"C 45","Reduction ratio":"12:1","lifecycle_stage":"current","Housing material":"Black anodized aluminium","Device short name":"GBX","Compatibility code":"GBX","Torsional rigidity":"2.5 N.m/arcmin","Maximum output torque":"619.6 lbf.in (70 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":"450 N 100 rpm, during 30000 hour at 30°C 600 N 100 rpm, during 10000 hour at 30°C","IP Degree of Protection":"Shaft output IP54","Maximum radial force Fr":"340 N 100 rpm, force applied at mid-distance from output shaft during 30000 hour at 30 °C 500 N 100 rpm, force applied at mid-distance from output shaft during 10000 hour at 30 °C","Continuous output torque":"389.4 lbf.in (44 N.m) 100 rpm 86 °F (30 °C)","Gearbox external diameter":"2.4 in (60 mm)","Product or Component Type":"Planetary gearbox","Maximum torsional backlash":"20 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/2383fdd52ed201b9dee99094f5f43aa3.pdf","sourceUrl":"https://www.se.com/nz/en/product/GBX0600121403F/gearbox-with-straight-teeth-gbx-ø-60-mm-reduction-121-20arcmin-44-n-m/","alternativesUrl":"https://aoctrl.com/api/mcp/products/GBX0600121403F/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy the GBX0600121403F and get a price?","answer":"No stock-holding claim is made — each order is verified against the supply channel."},{"question":"What is the continuous torque rating of the GBX0600121403F?","answer":"Continuous output torque is 44 N.m at 100 rpm and 30 °C ambient.
