Planetary construction packs higher torque density into the same envelope compared to parallel-shaft reducers — the load is shared across multiple planet gears orbiting the sun gear. Continuous output torque is 115 N.m at 100 rpm and 30 °C ambient, with a maximum intermittent torque of 184 N.m under the same conditions. Rated efficiency is 94 % — roughly 6 % of the input power is lost as heat through gear mesh friction and churning losses. For a 1 kW motor input, that is 60 W of heat to manage inside the enclosure; the black anodized aluminium housing radiates this without forced cooling in most panel environments. ## Backlash, rigidity, and load limits — the precision side of the spec Maximum torsional backlash is 9 arc-minutes. That is the angular play between input and output when the direction reverses — relevant for positioning axes where the gearbox sits between the motor and the load. For a ball-screw-driven axis, 9 arc-min at the gearbox output translates to roughly 0.025 mm of lost motion on a 10 mm lead screw, which may or may not matter depending on the positioning tolerance of the application. Torsional rigidity is 6 N.m/arcmin — the stiffness of the gear train under load. A 6 N.m load twists the output shaft by 1 arc-minute relative to the input. This stiffness figure, combined with the backlash, defines the total positioning error budget for the axis. Maximum radial force on the output shaft is 650 N at mid-shaft for the full 30000-hour service life, or 950 N for a reduced 10000-hour life. Maximum axial force is 1200 N for 10000 hours, dropping to 900 N for 30000 hours. These limits govern overhung loads from belt pulleys, chain sprockets, or direct-coupled loads — exceeding them shortens bearing life faster than the torque rating suggests. ## Environmental sealing and operating range Shaft output is rated IP54 — protected against dust ingress and splashing water from any direction. The housing itself is sealed, but the motor input interface and any breather or vent port must be considered separately for the overall drive assembly. Ambient operating temperature spans -25 °C to 90 °C. The 30 °C rating point for torque and life is conservative; operation at the upper end of the range will reduce the service life and may require derating the output torque. Noise level is 60 dB at 1 m, no-load — roughly the sound of a quiet office. Under load the noise increases with torque and speed; the straight-tooth profile is inherently noisier than helical gearing at higher speeds, but at 100 rpm the difference is small.","metaTitle":"Schneider GBX0800040552F planetary gearbox, 4:1, 115 N.m","metaDescription":"Schneider Electric GBX0800040552F planetary gearbox, 80 mm, 4:1 ratio, 115 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":"60 dB 1 m, no-load","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","Compatibility code":"GBX","Torsional rigidity":"6 N.m/arcmin","Maximum output torque":"1628.5 lbf.in (184 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":"1200 N 100 rpm, during 10000 hour at 30°C 900 N 100 rpm, during 30000 hour at 30°C","IP Degree of Protection":"Shaft output IP54","Maximum radial force Fr":"650 N 100 rpm, force applied at mid-distance from output shaft during 30000 hour at 30 °C 950 N 100 rpm, force applied at mid-distance from output shaft during 10000 hour at 30 °C","Continuous output torque":"1017.8 lbf.in (115 N.m) 100 rpm 86 °F (30 °C)","Gearbox external diameter":"3.1 in (80 mm)","Product or Component Type":"Planetary gearbox","Maximum torsional backlash":"9 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/663e2244f056053c00119bd18ccface7.pdf","sourceUrl":"https://www.se.com/ie/en/product/GBX0800040552F/gearbox-with-straight-teeth-gbx-ø-80-mm-reduction-41-9arcmin-115-n-m/","alternativesUrl":"https://aoctrl.com/api/mcp/products/GBX0800040552F/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/GBX0800040552F","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/GBX0800040552F when reusing this data.
