Continuous 450 N·m, peak 720 N·m — the load envelope that decides fit
The GBX1600041385D: The headline load envelope is 450 N·m continuous output torque against 720 N·m maximum output torque, which means sizing should ride the continuous figure, not the peak — the peak is a transient ceiling, not a duty rating. At the rated service life of 30000 h at 100 rpm and 30 °C, maximum axial thrust Fa is 6000 N and maximum radial load Fr is 4200 N when the radial force is applied at mid-distance from the output shaft. Push beyond those curves and the bearing life budget collapses; an MRO planner evaluating a swap needs to plot the actual applied Fr against this 4200 N line, not against the more generous 6000 N figure cited at the 10000 h short-life condition.
96 % efficiency, 70 dB, < 6 arcmin backlash — precision-class reducer
Efficiency is rated at 96 %, which is high for a single-stage planetary with straight-cut teeth — the straight-tooth geometry trades quieter helical behaviour for cost and simpler alignment, and the 70 dB noise figure at 1 m no-load reflects that. Backlash is held under 6 arcmin, and torsional rigidity is 38 N·m/arcmin, placing the GBX1600041385D in the precision-servo-adjacent class rather than the conveyor/agitator economy class. The shaft is C45 medium-carbon steel in a black anodised aluminium housing — a sensible material pairing when the radial and axial load envelopes above are respected.
Shaft seal IP54, –25…90 °C, any mounting position
The output shaft carries an IP54 seal — adequate for indoor panel-adjacent service but not a washdown-rated enclosure, so plant locations with coolant splash or outdoor exposure need a guarding decision at the gearbox, not just the motor. Operating envelope is –25 to 90 °C and the unit mounts in any position, which removes a constraint that often forces a specific reducer variant in skewed-drive conveyor layouts. The shaft moment of inertia is 7.78 g·cm² — a low figure that keeps the GBX1600041385D friendly to high-dynamic servo loops where added inertia erodes the bandwidth budget.
