Torque capacity and duty cycle
The GBX0600320402D is a 60 mm planetary gearbox with a 32:1 reduction ratio, delivering 44 N.m continuous output torque and a maximum of 70 N.m for peak loads. The 94% efficiency means roughly 6% of input power is lost to friction and windage — a figure that holds across the rated speed range, not just at a single operating point. Service life is specified at 30,000 hours at 100 rpm and 30 °C ambient — a common benchmark for continuous-duty indexing or conveyor drives. At higher loads or temperatures, the expected life shortens; the axial and radial force limits (450 N axial, 340 N radial at 100 rpm for the 30,000-hour target) define the bearing load envelope for the application.
Lifecycle reality — obsolete, sourced on RFQ
Schneider Electric lists this gearbox as obsolete. No direct successor order code is published. The GBX series shares a common 60 mm frame diameter and mounting pattern. If a replacement is needed for a new design, a parametric search on continuous torque (44 N.m), reduction ratio (32:1), and torsional backlash (25 arcmin) will identify functionally equivalent planetary gearboxes from other manufacturers — but no pin-compatible drop-in exists without verifying the shaft dimensions and mounting flange.
Mechanical integration notes
The housing is black anodized aluminium with a C45 steel output shaft. Shaft output sealing is IP54 — splash-resistant but not washdown-rated, so locate it away from direct spray or hose-down zones. The gearbox is lubricated for life and can be mounted in any position, which simplifies orientation in tight machine frames. Torsional rigidity is 2.5 N.m/arcmin — the shaft twist under load is low enough for positioning applications where the load does not reverse frequently. Moment of inertia at the input is 0.064 g.cm², a light rotor that allows the servo or stepper to accelerate quickly without oversizing the motor.
