Planetary gearbox for precision motion — 3:1 ratio, 28 N.m continuous
The GBX0600031001F is a planetary gearbox with straight teeth, 60 mm external diameter, and a 3:1 reduction ratio. It delivers a continuous output torque of 28 N.m (247.8 lbf.in) at 100 rpm and 30 °C, with a maximum output torque of 45 N.m (398.3 lbf.in) under the same conditions. Efficiency is rated at 94 %, and the no-load noise level is 58 dB measured at 1 m — quiet enough for indoor automation cells where operator exposure is a concern.
Load ratings and service life — what the numbers mean for your axis
Service life is 30,000 hours at 100 rpm and 30 °C, lubricated for life — no re-greasing interval to schedule. The maximum axial force (Fa) is 450 N at the same duty cycle, and the maximum radial force (Fr) is 340 N when applied at mid-distance from the output shaft. Torsional rigidity is 2.3 N.m/arcmin, and maximum torsional backlash is 16 arc.min — this is a standard-precision gearbox, not a zero-backlash unit, so it suits indexing and positioning where a few arc-minutes of lost motion are acceptable. The shaft output carries an IP54 degree of protection, meaning it resists dust ingress and splashing water — adequate for most enclosed machine builds but not washdown environments.
Obsolete status — sourcing through independent channels
Schneider Electric has marked the GBX0600031001F as obsolete. Available through independent surplus and broker channels — quantities are lot-specific and confirmed at RFQ. The housing is black anodized aluminium, the shaft is C 45 steel, and the gearbox is lubricated for life, so no field maintenance is required.
