Torque capacity and duty cycle — continuous vs peak
The GBX0400161001F: Rated continuous output torque is 20 N.m at 100 rpm and 30 °C ambient — this is the thermal limit for sustained operation, not a transient peak. Maximum output torque reaches 32 N.m under the same conditions, giving a 1.6× overload margin for acceleration or momentary load spikes before the gear teeth yield.
Lifecycle and sourcing — obsolete, sourced on request
Schneider Electric lists this GBX0400161001F as obsolete — no longer in active factory production. Available through independent surplus and broker channels; quantities and pricing are confirmed at RFQ against your BOM line.
Efficiency and thermal behaviour at the load point
94 % efficiency at rated load means 6 % of the input power dissipates as heat inside the gearbox housing — for a 20 N.m output at 100 rpm (roughly 210 W mechanical), the thermal loss is about 13 W. The black anodised aluminium housing (40 mm outer diameter) acts as the heat sink; the operating ambient range of -25 to 90 °C sets the enclosure temperature limit for adjacent components. Lubricated for life — no field regreasing interval, which simplifies maintenance but means the grease fill and seal condition determine the 30,000-hour service life at rated load.
Shaft loading and overhung load constraints
Maximum radial force on the output shaft is 200 N at 100 rpm for a 10,000-hour life, dropping to 160 N for the full 30,000-hour rating — both measured at mid-span on the shaft extension. Maximum axial force Fa is similarly 200 N (10,000 h) and 160 N (30,000 h) at 100 rpm — these limits govern belt-tension or direct-coupling loads on the output side. Shaft output IP54 rating means the output seal resists dust ingress and splashing water; the motor-side interface is unsealed and relies on the mating motor flange for environmental protection.
