Planetary gearbox, 40 mm frame, 8:1 reduction
The GBX0400081004F is a 40 mm-diameter planetary gearbox with straight-cut teeth and an 8:1 reduction ratio, delivering 6 N.m (53.1 lbf.in) continuous output torque at 100 rpm and 30 °C ambient. Rated efficiency sits at 94 %, with a noise floor of 55 dB measured at 1 m under no-load conditions — quiet enough for laboratory or light industrial benchtop integration. Maximum torsional backlash is 30 arc-min, which places this gearbox in the standard-precision range — adequate for positioning axes where sub-arc-minute repeatability is not required.
Duty ratings and mechanical limits
Service life is rated at 30,000 hours at 100 rpm and 30 °C; the gearbox is lubricated for life and requires no maintenance re-greasing in that window. Maximum axial force on the output shaft is 200 N at 100 rpm for a 10,000-hour life target, derating to 160 N for the full 30,000-hour service life at the same speed and temperature. The shaft output carries an IP54 ingress rating — protected against dust ingress and splashing water, but not submersion or high-pressure washdown. Operating ambient spans -25 °C to 90 °C, with the 6 N.m torque rating valid at the 30 °C reference point; higher ambient temperatures will require thermal derating per the manufacturer's curve.
Lifecycle and sourcing — obsolete, quoted to order
No official successor or direct drop-in replacement part number is published by the manufacturer for this frame size and ratio combination. Available through independent surplus and broker channels; quantities are lot-specific and confirmed at RFQ. Pricing and lead time are quoted per request against the BOM line.
