The GBX0400051404F is a Schneider Electric planetary gearbox with straight teeth, 40 mm external diameter, and a 5:1 reduction ratio. It delivers 14 N.m continuous output torque at 100 rpm and 30 °C, with a maximum intermittent torque of 22 N.m at the same speed and temperature. Rated service life is 30000 hours at 100 rpm and 30 °C — a working pull with documented runtime under that figure still carries meaningful remaining life. The unit is lubricated for life, so no field maintenance interval applies; the sealed housing means the lubricant condition is whatever it left the factory with. Efficiency is 94 % at rated load, which keeps thermal rise low in the drive train — relevant if this gearbox sits in a confined enclosure without forced cooling.
Load limits and mounting constraints
Maximum radial force on the output shaft is 200 N at 100 rpm for a 10000-hour life target, dropping to 160 N for the full 30000-hour rating. Axial force limits are identical — 200 N at 10000 hours, 160 N at 30000 hours. Both figures assume the force is applied at mid-distance from the output shaft face. Torsional backlash is 24 arc.min maximum — this is a standard-precision planetary, not a zero-backlash stage. For positioning applications requiring repeatability under 10 arc.min, this gearbox will need a downstream compensation or a higher-grade unit. The housing is black anodized aluminium, 40 mm diameter, with shaft output rated IP54. The IP rating applies to the output seal only — the motor interface side is not sealed, so the gearbox should be mounted with the motor flange facing down or protected from drip exposure. Ambient operating range is -25 to 90 °C, which covers most indoor industrial environments but not washdown or outdoor direct-sun exposure without a sun shield.
Sourcing reality — obsolete, sourced to order
Schneider Electric lists this gearbox as obsolete. Sourcing runs through independent surplus and decommissioning channels — quantities are lot-specific and confirmed at RFQ. No pin-compatible direct replacement is documented from the manufacturer. A functional replacement would require matching the 40 mm housing diameter, 5:1 ratio, 14 N.m continuous torque, and the motor interface flange pattern — a board spin or adapter plate is likely. Noise level is 55 dB at 1 m, no-load — useful for noise-budget planning if the gearbox runs in a quiet area. The straight-tooth design is inherently noisier than helical; this figure is typical for the class.
