It delivers a continuous output torque of 700 N.m at 100 rpm and a maximum torque of 1120 N.m under the same conditions — the number that governs sizing for a servo or stepper-driven axis. Rated service life is 30,000 hours at 100 rpm and 30 °C ambient, with the gearbox lubricated for life — no oil changes, no maintenance schedule beyond the bearing check at the motor end. The housing is black anodized aluminium, the output shaft is C45 steel. ## Torque, backlash, and force limits — what they mean for fit Maximum torsional backlash is 10 arc-minutes — this is the lost motion at the output when the input reverses direction. For a positioning axis that needs better than 0.1° repeatability at the load, that backlash has to be accounted for in the controller's reversal compensation or the axis will overshoot on direction changes. Torsional rigidity is 41 N.m/arcmin — a measure of how much the gearbox winds up under load. At the continuous torque of 700 N.m, the wind-up is about 17 arc-minutes (700 ÷ 41). That's elastic deflection, not backlash; the controller can't compensate for it unless the load torque is known and the stiffness is in the servo tuning model. Maximum radial force on the output shaft is 4200 N at mid-shaft for the 30,000-hour life, or 6000 N for a 10,000-hour duty cycle. Axial force limits are 6000 N and 8000 N respectively. These numbers decide whether the gearbox can handle a belt-drive or pinion load without overloading the output bearings — a belt tension that exceeds 4200 N radial will shorten life below the 30,000-hour rating. Efficiency is 94 % at rated load — typical for a single-stage planetary with straight teeth. The noise level is 70 dB at 1 m, no-load, which is moderate for a 160 mm frame; in a quiet lab environment you'll hear it, but on a production floor it's below ambient. ## Obsolete — sourced through independent channels Schneider Electric lists the GBX1600400704F as obsolete. The part is available through independent surplus and broker channels — quantities are lot-specific and confirmed at RFQ. For a line-down replacement, the key dimensions to match are the 160 mm housing diameter, the 40:1 ratio, and the output shaft interface. The continuous torque of 700 N.m and the 10 arc-min backlash set the performance floor for any substitute. No pin-compatible direct cross-reference exists in the current Schneider catalog — a mechanical adaptation may be needed.","metaTitle":"Schneider Electric GBX1600400704F Planetary Gearbox, 40:1","metaDescription":"Schneider Electric GBX1600400704F planetary gearbox, 160 mm diameter, 40:1 ratio, 700 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":"70 dB 1 m, no-load","Gear box type":"Straight teeth","Housing Colour":"Black","Shaft material":"C 45","Reduction ratio":"40:1","lifecycle_stage":"current","Housing material":"Black anodized aluminium","Device short name":"GBX","Compatibility code":"GBX","Torsional rigidity":"41 N.m/arcmin","Maximum output torque":"9912.8 lbf.in (1120 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":"6000 N 100 rpm, during 30000 hour at 30°C 8000 N 100 rpm, during 10000 hour at 30°C","IP Degree of Protection":"Shaft output IP54","Maximum radial force Fr":"4200 N 100 rpm, force applied at mid-distance from output shaft during 30000 hour at 30 °C 6000 N 100 rpm, force applied at mid-distance from output shaft during 10000 hour at 30 °C","Continuous output torque":"6195.5 lbf.in (700 N.m) 100 rpm 86 °F (30 °C)","Gearbox external diameter":"6.3 in (160 mm)","Product or Component Type":"Planetary gearbox","Maximum torsional backlash":"10 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/8c7409495da0e2de495ef548efe6ff53.pdf","sourceUrl":"https://www.se.com/ie/en/product/GBX1600400704F/gearbox-with-straight-teeth-gbx-ø-160-mm-reduction-401-10arcmin-700-n-m/","alternativesUrl":"https://aoctrl.com/api/mcp/products/GBX1600400704F/alternatives.json"},"ai":{"faq":[{"question":"What is the lead time for GBX1600400704F?","answer":"Lead time is quoted per order against the specific quantity.
