Planetary gearbox — 40 mm, 5:1 reduction, 14 N.m continuous
The GBX0400050704F is a straight-tooth planetary gearbox in a 40 mm diameter housing, delivering a 5:1 reduction ratio. Continuous output torque is 14 N.m at 100 rpm and 30 °C, with a maximum intermittent torque of 22 N.m under the same conditions. Efficiency is listed at 94 %, and the no-load noise level is 55 dB measured at 1 m — both figures apply at the rated speed and temperature.
Mechanical ratings and service life
Service life is specified as 30,000 hours at 100 rpm and 30 °C. The gearbox is lubricated for life, so no maintenance interval for oil changes applies. Maximum radial force (Fr) on the output shaft is 200 N at 100 rpm for a 10,000-hour life, derated to 160 N for the full 30,000-hour target. Maximum axial force (Fa) follows the same profile: 200 N for 10,000 hours, 160 N for 30,000 hours. Torsional rigidity is 1 N.m/arcmin, and maximum torsional backlash is 24 arc.min — this is a standard-precision grade, not a zero-backlash unit.
Environmental and construction details
The housing is black anodized aluminium; the shaft is C45 steel. Shaft output sealing is IP54, suitable for dry indoor environments but not washdown or outdoor exposure.
Lifecycle status and sourcing
Schneider Electric lists this gearbox as obsolete. Sourced through independent distribution channels against an RFQ.
