40 mm planetary gearbox — 4:1 reduction, 15 N.m continuous
The GBX0400041402F is a 40 mm diameter planetary gearbox from Schneider Electric's GBX series, with straight teeth and a 4:1 reduction ratio. It delivers 15 N.m continuous output torque at 100 rpm and 30 °C, with a maximum of 24 N.m under the same conditions. Rated efficiency is 94 %, and noise level at 1 m under no-load is 55 dB — both figures that hold up well for a straight-tooth planetary stage in this size class.
Torque, backlash, and service life — the numbers that govern fit
Continuous torque rating is 15 N.m; the maximum output torque of 24 N.m is the intermittent ceiling — design the load cycle so sustained operation stays below the continuous figure. Maximum torsional backlash is 30 arc.min, which is standard for a commercial-grade planetary stage; if the application needs tighter positioning repeatability, a low-backlash variant would be needed. Service life is specified at 30,000 hours at 100 rpm and 30 °C. The gearbox is lubricated for life, so no maintenance interval for oil changes — just monitor the load and ambient conditions. Maximum axial force (Fa) is 200 N and maximum radial force (Fr) is 200 N, both at 100 rpm for a 10,000-hour life at 30 °C. For the full 30,000-hour service life, both derate to 160 N. The radial force is measured at mid-distance from the output shaft.
Sourcing an obsolete GBX0400041402F — lifecycle and supply reality
Schneider Electric lists the GBX0400041402F as obsolete. This gearbox is sourced through independent distribution channels — quantities are confirmed at RFQ against the BOM line.
Mounting and environmental constraints
Shaft output protection is IP54 — the gearbox is sealed against dust ingress and splashing water at the output shaft, but not for washdown or submersion. Housing is black anodized aluminium; shaft material is C 45 steel. The 40 mm external diameter and 4:1 reduction fit into compact servo-drive or conveyor-drive layouts where a 40 mm frame size is specified.
