Both ratings are specified at 100 rpm and 30 °C ambient. If your application runs above 100 rpm or in a warmer enclosure, the allowable torque derates — the thermal limit is set by the lubricant and the aluminium housing's heat rejection. The gearbox is lubricated for life, so there is no oil-change interval to extend the thermal budget. ## Backlash and positioning accuracy — 16 arc.min maximum torsional backlash Maximum torsional backlash is 16 arc.min. For a 4:1 reduction, that translates to about 4 arc.min at the input side — enough for simple indexing or conveyor positioning, but not for precision servo axes that need single-arc-minute repeatability. The straight-tooth gear geometry (not helical) contributes to this backlash figure; helical gears in the same diameter class typically cut backlash by half. Torsional rigidity is 2.3 N.m/arcmin — the wind-up under load. At the continuous torque of 38 N.m, the elastic deflection is about 16.5 arcmin (38 ÷ 2.3), which adds to the geometric backlash. For a positioning move, the total lost motion is the sum of backlash plus wind-up at the operating torque. ## Overhung load limits — axial and radial force constraints at the output shaft Maximum axial force Fa is 450 N at 100 rpm for the full 30000-hour life, or 600 N if you accept a reduced 10000-hour service life. Maximum radial force Fr is 340 N at 100 rpm for 30000 hours, 500 N for 10000 hours — both measured with the force applied at mid-distance from the output shaft. These limits assume the shaft material is C45 steel, which is standard for this class. If your coupling or pulley overhangs beyond the mid-point, the effective radial load at the bearing increases linearly with distance. A belt drive or chain sprocket mounted at the shaft end will see roughly double the radial load compared to mid-point mounting — size the overhung distance accordingly or the bearing life drops below the 30000-hour target. ## Lifecycle status — obsolete, sourced through independent channels Schneider Electric lists the GBX0600040704F as obsolete. The part is available through independent surplus and broker channels — quantities are lot-specific and confirmed at RFQ. No pin-compatible direct replacement exists within the current GBX family; a functional substitute would require verifying the mounting flange, shaft diameter, and input interface against the BOM. The 60 mm housing diameter, 4:1 ratio, and 38 N.m continuous torque define the mechanical envelope. If you are sourcing a replacement for an existing machine, confirm the input bore size and keyway dimensions against the mating motor shaft before committing to a substitute. ## Environmental and noise considerations for the installation Noise level is 58 dB at 1 m, no-load — a quiet-running gearbox suitable for indoor production areas or laboratory environments. The straight-tooth design is inherently noisier than helical at higher speeds, but at 100 rpm the 58 dB figure is well below typical workshop background noise. Shaft output IP54 means the output seal is protected against dust ingress and splashing water, but the gearbox body itself is not sealed — the black anodized aluminium housing relies on the shaft seal as the primary wet-end barrier. Do not direct washdown spray at the output shaft area. Ambient operating range is -25 to 90 °C, covering most indoor and sheltered outdoor installations.","metaTitle":"Schneider Electric GBX0600040704F Planetary Gearbox, 4:1","metaDescription":"Schneider Electric GBX0600040704F planetary gearbox, 60 mm, 4:1 ratio, 38 N.m continuous torque, 94% efficiency.
