The 3:1 reduction ratio in a single planetary stage keeps the efficiency at 96 %, meaning about 4 % of input power is lost as heat through the straight-tooth mesh. Service life is rated 30,000 hours at 100 rpm and 30 °C ambient — that's roughly 3.4 years of continuous 24/7 operation before the grease degradation or bearing wear reaches end-of-life. The gearbox is lubricated for life, so no maintenance interval for oil changes. ## Mounting and environmental fit The 80 mm outer diameter housing is black anodized aluminium; shaft material is C45 carbon steel. Any mounting position is acceptable, which simplifies integration into tight machine frames or vertical-axis applications. Shaft output sealing is IP54 — protected against dust ingress and splashing water from any direction. The gearbox body itself is not sealed to the same level; the IP rating applies specifically at the output shaft lip seal. ## Backlash and rigidity — what the numbers mean for positioning Maximum torsional backlash is 12 arc-minutes — that's the angular play between input and output when reversing direction. For a 3:1 reducer, 12 arc-min at the output corresponds to about 4 arc-min at the input side. This is standard for commercial planetary gearboxes; if your application needs precision indexing below 5 arc-min, you'd step up to a low-backlash or preloaded series. Torsional rigidity is 6 N.m/arcmin — the stiffness of the gear train under load. At the continuous torque of 85 N.m, expect about 14 arc-min of windup from the gear mesh alone, before any shaft deflection. ## Shaft load capacities — axial and radial limits Maximum axial force (Fa) is 1200 N at 100 rpm for a 10,000-hour life, dropping to 900 N for the full 30,000-hour rating. Radial force (Fr) at mid-span on the output shaft is 950 N for 10,000 hours, 650 N for 30,000 hours. These are the limits for belt-drive or direct-coupling loads — exceeding them shortens bearing life faster than the torque rating would suggest. ## Noise and vibration profile Noise level is 60 dB at 1 m, no-load — roughly the sound of a quiet office or a low-hum motor. Under load the noise will increase, but the straight-tooth planetary design is inherently quieter than a helical gearbox of equivalent size. Moment of inertia is 0.77 g·cm² reflected to the input — low enough that servo or stepper systems won't lose significant acceleration torque spinning the gearbox itself.","metaTitle":"Schneider Electric GBX0800030841D planetary gearbox, 3:1","metaDescription":"Schneider Electric GBX0800030841D planetary gearbox, straight teeth, 3:1 reduction, 85 N.m continuous torque, 96% efficiency, IP54 shaft output.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Gear Reducers & Gearboxes"],"specifications":{"title":"GBX0800030841D","Efficiency":"96 %","Noise level":"60 dB at 1 m, no-load","description":"gearbox with straight teeth GBX- Ø 80 mm- reduction 3:1- < 12arcmin- 85 N.m","Gear box type":"Straight teeth","Housing colour":"Black","Shaft material":"C 45","Reduction ratio":"3:1","lifecycle_stage":"current","Housing material":"Black anodized aluminium","Device short name":"GBX","Moment Of Inertia":"0.77 g.cm²","Mounting position":"Any position","Compatibility code":"GBX","Torsional rigidity":"6 N.m/arcmin","Maximum output torque":"136 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":"85 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/25f7987ecdee2cea24f13c9d127bd545.pdf","sourceUrl":"https://www.se.com/ie/en/product/GBX0800030841D/gearbox-with-straight-teeth-gbx-ø-80-mm-reduction-31-12arcmin-85-n-m/"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to GBX0800030841D?","answer":"No direct pin-compatible alternative is listed in the Schneider GBX family for this exact 80 mm, 3:1 ratio variant.
