The maximum output torque reaches 416 N.m under the same conditions — this is the peak overload the gearbox can transmit before the straight-tooth mesh or bearings yield. Rated service life is 30000 hours at 100 rpm and 30 °C, with the gearbox lubricated for life — no oil-change interval to schedule. The operating ambient range spans -25 to 90 °C, which covers most indoor machine-tool and conveyor applications but may require derating above 30 °C for the torque figures. Efficiency is listed at 94 %, meaning 6 % of the input power is lost as heat in the gear mesh and bearings. For a motor driving a 260 N.m load at 100 rpm output (about 2.7 kW input), the heat rejection is roughly 160 W — enough to warm the black anodized aluminium housing but within the rated ambient if airflow is not blocked. ## Backlash, rigidity, and overhung load limits — the positioning constraints Maximum torsional backlash is 12 arc.min — this is the angular play between input and output when the direction reverses. For a positioning axis that indexes and holds, 12 arc.min at the output translates to about 0.35 mm of linear error on a 100 mm lever arm; if your application needs tighter repeatability, a gearbox with lower backlash (e.g., 3–5 arc.min) would be required. Torsional rigidity is 13 N.m/arcmin — the stiffness of the gear train under load. At the continuous torque of 260 N.m, the elastic wind-up is about 20 arc.min (260 ÷ 13), which adds to the backlash when the load is applied. This combined positioning error matters for servo-driven indexing tables or pick-and-place gantries. Maximum radial force (Fr) on the output shaft is 1500 N at 100 rpm for the 30000-hour life, rising to 2000 N for a 10000-hour life. Axial force (Fa) limits are 2100 N and 2800 N respectively. These forces must be applied at mid-distance from the output shaft — a belt drive or pinion mounted further out creates a bending moment that reduces the allowable radial load. The shaft material is C 45 medium-carbon steel, which is standard for this torque class. ## Obsolete — sourcing through independent channels Schneider Electric lists the GBX1200160551F as obsolete. The part is available through independent surplus and broker channels — quantities are lot-specific and confirmed at RFQ. For a machine-tool rebuild or MRO replacement, the 120 mm housing diameter, 16:1 ratio, and 260 N.m continuous torque define the form-fit-function envelope. Any substitute must match the output shaft dimensions, mounting flange pattern, and input bore to avoid a mechanical rework. The IP54 shaft output seal means the gearbox is splash-resistant but not washdown-rated — suitable for dry indoor environments with occasional coolant mist.","metaTitle":"Schneider Electric GBX1200160551F planetary gearbox, 16:1","metaDescription":"Schneider Electric GBX1200160551F planetary gearbox, 16:1 ratio, 260 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":"16:1","lifecycle_stage":"current","Housing material":"Black anodized aluminium","Device short name":"GBX","Compatibility code":"GBX","Torsional rigidity":"13 N.m/arcmin","Maximum output torque":"3681.9 lbf.in (416 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":"2301.2 lbf.in (260 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/917240b33279ab38a2073784bb447fa6.pdf","sourceUrl":"https://www.se.com/ca/en/product/GBX1200160551F/gearbox-with-straight-teeth-gbx-ø-120-mm-reduction-161-12arcmin-260-n-m/","alternativesUrl":"https://aoctrl.com/api/mcp/products/GBX1200160551F/alternatives.json"},"ai":{"faq":[{"question":"What is the noise level of GBX1200160551F?","answer":"The noise level is 65 dB measured at 1 m under no-load conditions.
