16:1 planetary reduction in a 40 mm package
The GBX0400161004F is a Schneider Electric planetary gearbox with straight teeth, 40 mm external diameter, and a 16:1 reduction ratio. It delivers 20 N.m continuous output torque at 100 rpm and 30 °C, with maximum torque reaching 32 N.m under the same conditions. Rated efficiency sits at 94 %, and noise output is 55 dB at 1 m under no-load — quiet enough for a packaging line or sorting station without an enclosure.
Torque, life, and the limits that matter
Continuous torque rating is 20 N.m at 100 rpm and 30 °C; push it to 32 N.m maximum but watch the duty cycle — the 30,000-hour service life is quoted at the continuous torque figure. Drop to 10,000 hours if you run at maximum torque continuously. Radial and axial force limits follow the same pattern: 200 N for 10,000 hours, 160 N for 30,000 hours, both measured at mid-distance on the output shaft at 100 rpm. The shaft output seal carries IP54 protection — fine for dry indoor environments but not washdown. Torsional rigidity is 1.1 N.m/arcmin, with maximum backlash of 28 arcmin. That's a standard-precision planetary — not a zero-backlash servo gearhead, but adequate for indexing conveyors and rotary tables where position repeatability is within a degree.
Obsolete — sourced through independent channels
Schneider Electric lists the GBX0400161004F as obsolete. No official successor or cross-reference is recorded from the manufacturer. The part is available through independent surplus distribution, with quantities confirmed at RFQ. The housing is black anodized aluminium, shaft material C 45 steel, and the unit ships lubricated for life — no maintenance ports or regrease intervals.
