Continuous output torque is 700 N.m and the maximum torque ceiling is 1120 N.m, which is the sizing number to use when calculating worst-case acceleration shocks rather than the steady-state figure. Torsional rigidity is listed at 41 N.m/arcmin and maximum torsional backlash is 10 arc.min, so positioning applications need to budget that backlash into the reversal error — at the output shaft that is roughly 0.058 mm of lost motion per metre of travel before closed-loop correction kicks in. ## Shaft loads, seals, and the duty envelope The maximum radial load is 4200 N over the 30000 h service life at mid-shaft and 6000 N over a 10000 h life — the lower figure is what governs if you actually run to the rated life at 100 rpm. Maximum axial force Fa is 6000 N over 30000 h and 8000 N over 10000 h, so a direct-coupled screw or heavy pulley needs to be checked against the 10000 h figure if the loading runs high. The shaft output is sealed to IP54, which keeps casual dust and drips out but is not a washdown rating — outdoor or food-grade duty needs an enclosure or a cover shield over the output seal. Operating ambient range is -25 to 90 °C and the unit is lubricated for life, so there is no scheduled oil change to roll into maintenance planning — the 30000 h figure is the practical overhaul interval at 100 rpm and 30 °C. ## Efficiency, acoustics, and what they cost Listed efficiency is 94 %, which for a planetary stage with straight-cut gearing sets a per-stage loss floor; from that figure plus the duty cycle the heat rejection into the cabinet can be sized rather than measured. Noise level is 70 dB at 1 m no-load, so at full load with the motor coupled the cabinet acoustic treatment needs to be designed around that baseline rather than the drive-only noise figure. ## Sourcing posture for the BOM line Mounting position is listed as any position, which matters for retrofit cabinets where the gearbox has to follow the existing shaft alignment rather than the preferred orientation.","metaTitle":"Schneider Electric GBX1600251082D planetary gearbox, 25:1","metaDescription":"Schneider Electric GBX1600251082D planetary gearbox, 25:1 reduction, 700 N.m continuous torque, 160 mm frame.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Gear Reducers & Gearboxes"],"specifications":{"title":"GBX1600251082D","Efficiency":"94 %","Noise level":"70 dB at 1 m, no-load","description":"gearbox with straight teeth GBX- Ø 160 mm- reduction 25:1- < 10arcmin- 700 N.m","Gear box type":"Straight teeth","Housing colour":"Black","Shaft material":"C 45","Reduction ratio":"25:1","lifecycle_stage":"current","Housing material":"Black anodized aluminium","Device short name":"GBX","Moment Of Inertia":"5.81 g.cm²","Mounting position":"Any position","Compatibility code":"GBX","Torsional rigidity":"41 N.m/arcmin","Maximum output torque":"1120 N.m","Service life in hours":"30000 h at 100 rpm at 30 °C","Additional information":"Lubricated for life","Maximum axial force Fa":"6000 N at 100 rpm, during 30000 hour at 30°C 8000 N at 100 rpm, during 10000 hour at 30°C","IP degree of protection":"Shaft output: IP54","Maximum radial force Fr":"4200 N at 100 rpm, force applied at mid-distance from output shaft during 30000 hour at 30 °C 6000 N at 100 rpm, force applied at mid-distance from output shaft during 10000 hour at 30 °C","Continuous output torque":"700 N.m","Gearbox external diameter":"160 mm","Product or component type":"Planetary gearbox","Maximum torsional backlash":"10 arc.min","Ambient Temperature For Operation":"-25...90 °C"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/db3f4dd8cab2d94ab0f79f230fc8b581.pdf","sourceUrl":"https://www.se.com/ie/en/product/GBX1600251082D/gearbox-with-straight-teeth-gbx-ø-160-mm-reduction-251-10arcmin-700-n-m/"},"ai":{"faq":[{"question":"Where can I source GBX1600251082D and how is it quoted?","answer":"No stock-on-hand or ship-date number is asserted on-page."},{"question":"What is the listed noise level for GBX1600251082D at no-load?","answer":"70 dB at 1 m, no-load — cabinet acoustic treatment should be designed against that baseline with the motor coupled."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/GBX1600251082D","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/schneider/GBX1600251082D when reusing this data.
