The continuous figure governs the thermal steady-state — running a conveyor or rotary indexer at 115 N.m keeps the gear mesh temperature within the 30,000-hour service life window at 100 rpm and 30 °C. The 4:1 reduction ratio means the input speed is four times the output speed, and the input torque is one-quarter of the output torque (less the 4% loss from 96% efficiency). That efficiency figure is the thermal budget — 4% of the transmitted power becomes heat inside the housing. ## Load ratings at 100 rpm — bearing life under radial and axial forces Maximum radial force Fr is 650 N at 100 rpm for the 30,000-hour service life, applied at mid-distance from the output shaft. For a 10,000-hour duty cycle, that rises to 950 N at the same speed. Maximum axial force Fa is 900 N at 100 rpm for 30,000 hours, or 1200 N for 10,000 hours at 30 °C. These are the limits for belt-drive or direct-coupled loads — exceeding them shortens the bearing life faster than the gear tooth wear. ## Backlash and torsional rigidity — positioning accuracy in servo loops Maximum torsional backlash is 12 arc.min, and torsional rigidity is 6 N.m/arcmin. For a pick-and-place or indexing axis, the 12 arc.min backlash means the output shaft can rotate up to 0.2° before the gear teeth engage in the reverse direction — acceptable for general positioning, not for zero-backlash cam-follower applications. ## Mounting and environmental fit for the press-side layout The gearbox mounts in any position — horizontal, vertical shaft-up, or vertical shaft-down — which simplifies integration into a tire-curing press where the gearbox may sit beside the steam platen. The 80 mm external diameter and black anodized aluminium housing keep the envelope compact and corrosion-resistant. Shaft output sealing is IP54, meaning dust-protected and splash-resistant — adequate for the dry side of a press cell, but not for washdown zones. Lubricated for life — no oil-change interval to schedule in the PM plan. The straight-tooth spur gear set is noisier than helical, but the 60 dB at 1 m (no-load) is within typical industrial floor limits.","metaTitle":"Schneider Electric GBX0800040703D Planetary Gearbox","metaDescription":"Schneider Electric GBX0800040703D planetary gearbox, 80 mm diameter, 4:1 reduction, 115 N.m continuous torque, 96% efficiency.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Gear Reducers & Gearboxes"],"specifications":{"title":"GBX0800040703D","Efficiency":"96 %","Noise level":"60 dB at 1 m, no-load","description":"gearbox with straight teeth GBX- Ø 80 mm- reduction 4:1- < 12arcmin- 115 N.m","Gear box type":"Straight teeth","Housing colour":"Black","Shaft material":"C 45","Reduction ratio":"4:1","lifecycle_stage":"current","Housing material":"Black anodized aluminium","Device short name":"GBX","Moment Of Inertia":"0.52 g.cm²","Mounting position":"Any position","Compatibility code":"GBX","Torsional rigidity":"6 N.m/arcmin","Maximum output torque":"184 N.m","Service life in hours":"30000 h at 100 rpm at 30 °C","Additional information":"Lubricated for life","Maximum axial force Fa":"1200 N at 100 rpm, during 10000 hour at 30°C 900 N at 100 rpm, during 30000 hour at 30°C","IP degree of protection":"Shaft output: IP54","Maximum radial force Fr":"650 N at 100 rpm, force applied at mid-distance from output shaft during 30000 hour at 30 °C 950 N at 100 rpm, force applied at mid-distance from output shaft during 10000 hour at 30 °C","Continuous output torque":"115 N.m","Gearbox external diameter":"80 mm","Product or component type":"Planetary gearbox","Maximum torsional backlash":"12 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/f274a325b48a8dc3730a7ff43102c27d.pdf","sourceUrl":"https://www.se.com/nl/en/product/GBX0800040703D/gearbox-with-straight-teeth-gbx-ø-80-mm-reduction-41-12arcmin-115-n-m/"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/GBX0800040703D","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/GBX0800040703D when reusing this data.
