Planetary construction gives it higher torque density and better load sharing than a parallel-shaft box of the same size — the 210 N.m continuous output torque at 100 rpm comes from a package that fits where a helical gearbox wouldn't. Rated for 30,000 hours service life at 100 rpm and 30 °C ambient, with the maximum output torque peaking at 336 N.m under the same conditions. That continuous-versus-maximum spread — 210 N.m vs 336 N.m — tells you the duty cycle margin: intermittent peak loads up to 60% over continuous are fine, but sustained operation above 210 N.m will shorten the 30,000-hour life target. ## Torque, backlash, and stiffness — the fit decisions Maximum torsional backlash is 12 arc-minutes, which sets the positioning repeatability floor. For a pick-and-place axis indexing through a 9:1 ratio, that 12 arc-min at the output translates to roughly 1.3 arc-min at the motor — enough that a servo system with high-resolution encoder may need backlash compensation in the drive tuning. The torsional rigidity of 13 N.m/arcmin means the gearbox winds up 0.08 arc-min per N.m of load torque; in a rigidly coupled system with frequent reversals, that windup shows up as lost motion unless the controller accounts for it. Axial and radial force limits are specified at 100 rpm: 2100 N axial (Fa) and 1500 N radial (Fr) for the 30,000-hour life, stepping up to 2800 N and 2000 N respectively if you accept a 10,000-hour service life. The radial force assumes the load is applied at mid-distance from the output shaft — an overhung load closer to the housing face can take higher Fr, but a sprocket or pulley mounted further out reduces the allowable force. These numbers govern bearing life, not tooth strength; exceeding them wears the output bearings before the gears. ## Efficiency, noise, and environmental fit 94% efficiency at rated load means about 6% of the input power becomes heat. For a 210 N.m output at 100 rpm (roughly 2.2 kW mechanical), that's about 130 W of heat to dissipate through the black anodized aluminium housing. In a sealed enclosure with no airflow, that heat builds — the -25 to 90 °C operating range gives headroom, but a duty cycle above 60% may need ventilation. Noise level is 65 dB at 1 m, no-load — straight-cut teeth are inherently noisier than helical, so this is the gearbox you spec when cost and simplicity matter more than quiet operation. The IP54 rating on the shaft output means it's protected against splashing water and dust ingress from most directions, but not against pressurized washdown or immersion. Lubricated for life with no maintenance interval — one less line item on the PM schedule. ## Sourcing an obsolete gearbox — what that means For a one-off MRO swap or a short production run, the gearbox is available to order through our sourcing desk — we quote against your BOM quantity and confirm availability at quote time. No stock-holding claim; each order is sourced individually from the independent channel.","metaTitle":"Schneider Electric GBX1200090702F Planetary Gearbox","metaDescription":"Schneider Electric GBX1200090702F planetary gearbox, 9:1 reduction, 210 N.m continuous torque at 100 rpm, 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":"9:1","lifecycle_stage":"current","Housing material":"Black anodized aluminium","Device short name":"GBX","Compatibility code":"GBX","Torsional rigidity":"13 N.m/arcmin","Maximum output torque":"2973.8 lbf.in (336 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":"1858.7 lbf.in (210 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":"12 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/d258cc71389267c2f956e97b08adf8ea.pdf","sourceUrl":"https://www.se.com/nz/en/product/GBX1200090702F/gearbox-with-straight-teeth-gbx-ø-120-mm-reduction-91-12arcmin-210-n-m/","alternativesUrl":"https://aoctrl.com/api/mcp/products/GBX1200090702F/alternatives.json"},"ai":{"faq":[{"question":"What is the continuous torque rating of the GBX1200090702F at 100 rpm?","answer":"210 N.m (1858.7 lbf.in) continuous output torque at 100 rpm and 30 °C ambient.
