Obsolete — sourcing through independent channels
Schneider Electric has classified the GBX0400160703F as obsolete. This planetary gearbox is available through independent surplus and broker channels. Quantities are lot-specific and confirmed at RFQ — no stock-holding claim is made here.
16:1 reduction, 20 N.m continuous — what the ratings mean
The 16:1 reduction ratio steps motor speed down by a factor of 16 while multiplying torque. Continuous output torque is 20 N.m (177.01 lbf.in) at 100 rpm and 30 °C — this is the torque the gearbox can deliver indefinitely without exceeding its thermal or mechanical limits. Maximum output torque is 32 N.m (283.2 lbf.in) at the same speed and temperature — the peak torque available for acceleration or momentary overloads. The 94 % efficiency means 6 % of input power is lost as heat inside the housing. Service life is rated at 30,000 hours at 100 rpm and 30 °C. The gearbox is lubricated for life — no maintenance re-greasing interval.
Mounting constraints and environmental limits
The 40 mm external diameter and straight-tooth planetary design fit into compact actuator assemblies. Housing is black anodized aluminium; the shaft is C45 steel. Shaft output seal is rated IP54 — splash protection, not submersion. Ambient operating range is -25 to 90 °C. Maximum axial force on the output shaft is 200 N for a 10,000-hour life at 30 °C, dropping to 160 N for the 30,000-hour rating. Radial force limits follow the same profile. Maximum torsional backlash is 28 arc.min — the angular play between input and output when reversing direction. Torsional rigidity is 1.1 N.m/arcmin, which defines the stiffness of the gear train under load.
