Rated service life is 30,000 hours at 100 rpm and 30 °C, with the gearbox lubricated for life — no maintenance interval for oil changes, which simplifies the BOM for sealed-drive assemblies. ## Sourcing reality — obsolete, quoted to order Available through independent surplus and broker channels. No stock-holding claim is made here. ## Mechanical constraints for integration The 120 mm diameter black anodized aluminium housing with straight teeth and C 45 steel shaft carries an IP54 rating at the shaft output — suitable for environments where dust ingress and splash are present but not pressurized washdown. Maximum axial force Fa is 2100 N at 100 rpm for the 30,000-hour service life, and maximum radial force Fr is 1500 N applied at mid-distance from the output shaft under the same conditions — these set the bearing load limits for the driven component. Torsional rigidity is 12 N.m/arcmin, and maximum torsional backlash is 8 arc.min — the backlash figure governs positioning repeatability in reversing or servo-type applications. ## Efficiency and noise profile Rated 94 % efficiency means 6 % of input power is lost as heat — a 1 kW input yields 940 W mechanical output, with the 60 W thermal loss dissipated through the aluminium housing. No additional cooling is required within the -25 to 90 °C ambient range. Noise level is 65 dB at 1 m under no-load conditions — roughly the level of a normal conversation, which is acceptable for most industrial environments without acoustic enclosures.","metaTitle":"Schneider Electric GBX1200040704F Planetary Gearbox, 4:1","metaDescription":"Schneider Electric GBX1200040704F planetary gearbox. 4:1 reduction, 155 N.m continuous torque, 94% efficiency.
