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 minus the 94 % efficiency loss — so about 30.6 N.m continuous at the input side. The 94 % efficiency figure is the mechanical loss floor through the straight-teeth planetary stage at rated load. That 6 % loss shows up as heat inside the housing — the black anodised aluminium body (80 mm diameter) dissipates it, but a duty cycle above the continuous torque rating will drive the internal temperature above the -25 to 90 °C ambient operating range. ## Shaft loading limits and service life The output shaft (C 45 steel) can take 1200 N axial force (Fa) for 10000 hours at 30 °C and 100 rpm, dropping to 900 N if you want the full 30000-hour service life. Radial force (Fr) applied at mid-shaft is 950 N for 10000 hours or 650 N for 30000 hours. These are hard limits — overshoot them and the bearing life collapses faster than the 30000-hour lubricated-for-life grease charge. The IP54 rating on the shaft output means the seal keeps out dust and splashing water, but it is not submersible or washdown-rated. In a food or wet environment, you would need a secondary cover over the output end. ## Backlash and positioning accuracy Maximum torsional backlash is 9 arcmin — that is the lost motion between input and output when reversing direction. For a 4:1 gearbox this is a standard commercial-grade figure; if your application needs less than 3 arcmin for precision indexing, this straight-teeth planetary will not hold the position repeatability you need. Torsional rigidity is 6 N.m/arcmin — meaning a 6 N.m load twist on the output shaft produces 1 arcmin of elastic deflection on top of the backlash. That stiffness matters when the gearbox is between a servo motor and a load that reverses quickly. ## Obsolete — sourcing through independent channels Schneider Electric has marked the GBX0800041004F as obsolete. The part is available through independent surplus and broker channels — quantities are lot-specific and confirmed at the time of quote. No pin-compatible or form-fit-function replacement is documented by Schneider for this specific frame size and ratio. If you are qualifying a substitute, you will need to compare the 80 mm diameter, 4:1 ratio, 115 N.m continuous torque, and 9 arcmin backlash against other planetary gearboxes in the same envelope.","metaTitle":"Schneider Electric GBX0800041004F Planetary Gearbox, 4:1","metaDescription":"Obsolete Schneider GBX0800041004F planetary gearbox, 80 mm, 4:1 ratio, 115 N.m continuous torque, 94% efficiency.","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/191cf4caa039a9ee0b9f7cae1a7cc2b5.pdf","sourceUrl":"https://www.se.com/ie/en/product/GBX0800041004F/gearbox-with-straight-teeth-gbx-ø-80-mm-reduction-41-9arcmin-115-n-m/","alternativesUrl":"https://aoctrl.com/api/mcp/products/GBX0800041004F/alternatives.json"},"ai":{"faq":[{"question":"What is the continuous output torque of GBX0800041004F?","answer":"The continuous output torque is 115 N.m (1017.8 lbf.in) at 100 rpm and 30 °C.
