The GBX1600400551F is a straight-tooth planetary gearbox with a 40:1 reduction ratio, sized for a 160 mm output stage. The continuous output torque is 700 N.m at 100 rpm and 30 °C, with a maximum intermittent rating of 1120 N.m at the same speed and temperature — the margin covers acceleration peaks and occasional overloads without oversizing the next axis component. Torsional rigidity is 41 N.m/arcmin, and maximum backlash is held to 10 arc-min. That combination matters for positioning accuracy in a servo-driven rotary table or a pick-and-place gantry where the load reversal error stacks with the ballscrew or belt compliance. Efficiency is listed at 94 % — the straight-tooth profile trades a small noise penalty (70 dB at 1 m, no-load) for lower sliding losses compared to helical gearing, which keeps the thermal rise lower in a sealed, lubricated-for-life housing.
Shaft loads and service life — the envelope that governs the bearing selection
Rated service life is 30,000 hours at 100 rpm and 30 °C. The maximum radial force Fr at the output shaft mid-point is 4200 N for the full 30,000-hour life, or 6000 N if the application accepts a reduced 10,000-hour bearing life. Maximum axial force Fa follows the same dual-rating pattern: 6000 N for 30,000 hours, 8000 N for 10,000 hours. The shaft output seal carries an IP54 ingress rating — suitable for dry indoor environments with occasional dust or splash, but not washdown. The housing is black anodized aluminium; the shaft is C45 steel. Ambient operating range is -25 to 90 °C. The gearbox is lubricated for life, so there is no maintenance schedule for oil changes — the seal and bearing condition define the replacement interval.
Obsolete — sourcing the GBX1600400551F through independent channels
Schneider Electric lists this planetary gearbox as obsolete. Available through independent surplus and broker channels. Quantities are lot-specific and confirmed at RFQ — no stock-holding claim is made here. The lubricated-for-life design means storage condition matters: units that have sat for years should be rotated by hand to redistribute the grease before installation.
