Efficiency on this gear train is 94 %, with a continuous output torque of 700 N.m and a maximum output torque of 1120 N.m — the maximum figure is the short-duration overload ceiling, while the 700 N.m figure is the duty the gearbox holds continuously without accelerated wear. Torsional backlash is held under 10 arc.min and torsional rigidity is 41 N.m/arcmin, so the unit is sized for positioning work where return error after a direction reversal matters more than raw throughput. ## Service life and the load envelope at the output shaft Service life is rated at 30,000 hours when run at 100 rpm and 30 °C ambient — that is the reference duty the radial and axial load figures are anchored to. Maximum radial force Fr is 4200 N at 100 rpm over the 30,000-hour life (6000 N over a 10,000-hour life), applied at mid-distance from the output shaft; maximum axial force Fa is 6000 N over the 30,000-hour life (8000 N over a 10,000-hour life) at the same speed and temperature. Moment of inertia at the input is 5.81 g.cm², low enough that adding the gearbox to a servo loop does not meaningfully extend the acceleration time constant — the inertia budget is governed by the driven load, not the reducer. ## Environment, sealing, and the housing envelope Operating ambient is -25 to 90 °C, with IP54 protection at the shaft output — dust-protected and splash-resistant, not a washdown-rated seal, so the unit belongs inside an enclosure or on a sheltered machine, not on open outdoor equipment. ## Lifecycle and the buying path Buyers arriving at the GBX1600250843D with a BOM line in hand are typically working from a quote against a confirmed quantity, since independent distribution sources to order with lead time and pricing confirmed at RFQ.","metaTitle":"Schneider Electric GBX1600250843D Planetary Gearbox, 25:1","metaDescription":"Schneider Electric GBX1600250843D planetary gearbox, 160 mm frame, 25:1 reduction, 700 N.m continuous output torque, 94 % efficiency.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Gear Reducers & Gearboxes"],"specifications":{"title":"GBX1600250843D","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/94203c437479e759a2abf987a47c2f5b.pdf","sourceUrl":"https://www.se.com/ie/en/product/GBX1600250843D/gearbox-with-straight-teeth-gbx-ø-160-mm-reduction-251-10arcmin-700-n-m/"},"ai":{"faq":[{"question":"What is GBX1600250843D's listed efficiency?","answer":"94 % efficiency on the gear train, with continuous output torque rated at 700 N.m and a maximum of 1120 N.m."},{"question":"What is GBX1600250843D's noise level?","answer":"70 dB measured at 1 m under no-load condition."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/GBX1600250843D","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/GBX1600250843D when reusing this data.
