40:1 planetary reduction, 40 N.m continuous
The GBX0600400702F is a straight-tooth planetary gearbox from Schneider Electric's GBX series, delivering a 40:1 reduction ratio with a continuous output torque of 40 N.m at 100 rpm and 30 °C ambient. Maximum output torque reaches 64 N.m under the same conditions, with a torsional rigidity of 2.5 N.m/arcmin and a maximum backlash of 20 arc.min — suitable for positioning applications that can tolerate that angular play.
Efficiency, noise, and service life
Rated efficiency is 94 %, which means 6 % of input power is lost as heat — a typical figure for a single-stage planetary with straight teeth. Noise level is 55 dB at 1 m under no-load, and the service life is specified at 30,000 hours at 100 rpm and 30 °C — lubricated for life, so no maintenance re-greasing is needed.
Obsolete — sourcing through independent channels
It is available through independent surplus and broker channels; quantities are confirmed at RFQ, and no direct OEM replacement has been published.
Mechanical interface and environmental limits
The gearbox has a 60 mm outer diameter, black anodised aluminium housing, and a C45 steel output shaft. Shaft output sealing is rated IP54 — suitable for dry indoor environments but not for washdown or direct spray. Maximum axial force on the output shaft is 450 N for the full 30,000-hour life, and maximum radial force (applied at mid-shaft) is 340 N under the same duty.
