The 96% efficiency figure is the headline mechanical performance metric — it means only 4% of the input power is lost to friction and windage inside the gear train, which keeps the heat rise low and allows the gearbox to run cooler under continuous duty. For a motor-gearbox pair on a conveyor or indexing station, that efficiency directly reduces the motor current draw needed to deliver the output torque. ## Load ratings and service life at 100 rpm The service life is specified as 30,000 hours at 100 rpm and 30 °C ambient. At that same speed, the maximum axial force Fa is 200 N for a 10,000-hour life or 160 N for the full 30,000-hour window; the radial force Fr at mid-span on the output shaft follows the same 200 N / 160 N split. These are the numbers a design engineer uses to check whether the gearbox survives the overhung load from a pulley or sprocket, or the thrust from a lead screw, over the target machine lifetime. ## Backlash and torsional rigidity for positioning Maximum torsional backlash is 30 arcmin — this is the angular play between input and output when the direction reverses. For a simple speed-reduction conveyor drive, 30 arcmin is acceptable; for a servo-driven rotary table or pick-and-place axis where the controller expects zero lost motion, a lower-backlash gearbox (e.g. the GBX series with <10 arcmin) would be the correct selection. Torsional rigidity is 1 N.m/arcmin, meaning the gearbox twists 1 arcmin for every N.m of applied torque — stiff enough for most indexing applications but not in the zero-backlash harmonic-drive class. ## Environmental fit: IP54, temperature range, lubrication The shaft output seal carries IP54 protection — splash-resistant but not submersible, so the gearbox suits indoor conveyor lines, packaging machinery, or light wash-down zones where it is not directly hosed. It is lubricated for life, which eliminates the need for periodic grease changes and the risk of running dry after a missed maintenance cycle — a practical advantage for MRO planners managing a large fleet of drives. ## Noise and inertia — acoustic and dynamic profile Noise level is 55 dB at 1 m under no-load conditions — roughly the sound of a quiet office, not silent but unlikely to push a machine past typical 85 dBA shop-floor limits. Moment of inertia is 0.019 g.cm², a low figure that allows the gearbox to accelerate and decelerate quickly when paired with a servo motor; the reflected inertia at the motor shaft is the gearbox inertia divided by the square of the reduction ratio (5² = 25), so the motor sees under 0.001 g.cm² from the gearbox alone.","metaTitle":"Schneider Electric GBX0400050402D Planetary Gearbox, 5:1","metaDescription":"Schneider Electric GBX0400050402D planetary gearbox, 40 mm diameter, 5:1 reduction, 96% efficiency, 30 arcmin backlash.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Gear Reducers & Gearboxes"],"specifications":{"title":"GBX0400050402D","Efficiency":"96 %","Noise level":"55 dB at 1 m, no-load","description":"gearbox with straight teeth GBX- Ø 40 mm- reduction 5:1- < 30arcmin- 14 N.m","Gear box type":"Straight teeth","Housing colour":"Black","Shaft material":"C 45","Reduction ratio":"5:1","lifecycle_stage":"current","Housing material":"Black anodized aluminium","Device short name":"GBX","Moment Of Inertia":"0.019 g.cm²","Mounting position":"Any position","Compatibility code":"GBX","Torsional rigidity":"1 N.m/arcmin","Service life in hours":"30000 h at 100 rpm at 30 °C","Additional information":"Lubricated for life","Maximum axial force Fa":"200 N at 100 rpm, during 10000 hour at 30°C 160 N at 100 rpm, during 30000 hour at 30°C","IP degree of protection":"Shaft output: IP54","Maximum radial force Fr":"200 N at 100 rpm, force applied at mid-distance from output shaft during 10000 hour at 30 °C 160 N at 100 rpm, force applied at mid-distance from output shaft during 30000 hour at 30 °C","Gearbox external diameter":"40 mm","Product or component type":"Planetary gearbox","Maximum torsional backlash":"30 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/d7190ba7e30fc47c8e11b36e3b12c39f.pdf","sourceUrl":"https://www.se.com/nl/en/product/GBX0400050402D/gearbox-with-straight-teeth-gbx-ø-40-mm-reduction-51-30arcmin-14-n-m/"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/GBX0400050402D","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/GBX0400050402D when reusing this data.
