60 mm planetary gearbox — 9:1 reduction, 44 N.m continuous
The GBX0600091004F is a 60 mm-diameter planetary gearbox with straight-cut teeth, delivering a 9:1 reduction ratio. Continuous output torque is 44 N.m at 100 rpm and 30 °C; maximum output torque reaches 70 N.m under the same conditions — the gap between continuous and max defines the overload headroom for intermittent peaks. Rated service life is 30,000 hours at 100 rpm and 30 °C, lubricated for life with no scheduled regreasing. The 94 % efficiency figure means about 6 % of input power dissipates as heat inside the housing — in a sealed 60 mm aluminium body, that heat path is conduction through the mounting flange, so the duty cycle and ambient temperature directly govern the thermal balance.
Load ratings — axial force, radial force, and the 100 rpm anchor
Maximum axial force on the output shaft is 450 N for the full 30,000-hour life, or 600 N if the application accepts a shorter 10,000-hour bearing life. Radial force limits follow the same pattern: 340 N for 30,000 hours, 500 N for 10,000 hours, both measured at mid-span on the output shaft. All force ratings are anchored at 100 rpm and 30 °C — higher speeds or temperatures reduce these limits, and no derating curve is published for this series. Torsional rigidity is 2.5 N.m/arcmin, with a maximum torsional backlash of 20 arcmin. That backlash figure is the total angular play under reversing load — acceptable for general positioning and indexing, but not for precision servo axes that need single-digit arcmin repeatability.
Obsolete — sourcing through independent channels
Schneider Electric lists the GBX0600091004F as obsolete. No official successor or pin-compatible replacement is published by the manufacturer. The part is available through independent surplus and broker channels; quantities are lot-specific and confirmed at RFQ.
