12:1 planetary reduction with 44 N.m continuous torque
The GBX0600120584D is a 60 mm-diameter planetary gearbox with straight teeth and a 12:1 reduction ratio, delivering 44 N.m continuous output torque and a peak of 70 N.m maximum output torque. The 94 % efficiency means minimal power loss through the reduction stage — useful for battery-powered or thermally constrained applications where every watt counts. Rated service life is 30,000 hours at 100 rpm and 30 °C ambient, with the gearbox lubricated for life — no maintenance schedule for oil changes. The IP54 rating at the shaft output means it resists dust ingress and splashing water, but not washdown; keep it inside a cabinet or under a drip shield.
Load capacity and stiffness limits
Maximum axial force on the output shaft is 450 N at 100 rpm for the full 30,000-hour life, or 600 N if you accept a 10,000-hour service window. Radial force limits are 340 N and 500 N respectively, measured at mid-distance on the output shaft — overhung loads need a check against this curve. Torsional rigidity is 2.5 N.m/arcmin, and maximum torsional backlash is 25 arc.min — that's a standard-precision planetary, not a zero-backlash unit. If your positioning loop demands under 10 arc.min, this gearbox introduces too much windup for servo duty without compensation. Moment of inertia reflected to the input is 0.127 g.cm² — low enough that a small servo or stepper can accelerate the load without the gearbox dominating the inertial mismatch.
Obsolete — last-time-buy sourcing only
Schneider Electric lists the GBX0600120584D as obsolete. No official successor or cross-reference is recorded from the manufacturer — this is a discontinued line, not a superseded part number. The GBX series planetary gearboxes have been replaced by newer families with different mounting dimensions and ratios. Available through independent surplus and last-time-buy channels. Quantities are lot-specific — we source against your BOM quantity and confirm availability at RFQ. If you need a guaranteed long-term supply for a production line, budget for a requalification to a current-generation planetary gearbox with the same 60 mm frame size and 12:1 ratio.
