Lifecycle reality — obsolete, but we hold stock
The GBX0600090584D: We carry remaining inventory of this exact planetary gearbox, sourced through independent channels for buyers who need to keep existing BOM lines running without a redesign.
What the 9:1 reduction and 44 N.m mean for your axis
The 9:1 reduction ratio drops motor speed by a factor of nine while multiplying torque — the continuous output torque rating of 44 N.m is the figure that governs steady-state operation, not the 70 N.m maximum which is a peak overload limit. At 100 rpm output, the service life is rated at 30,000 hours at 30 °C ambient — the gearbox is lubricated for life, so no maintenance schedule for oil changes.
Efficiency, backlash, and noise — the precision metrics
94% efficiency means 6% of input power is lost as heat through the straight-tooth planetary stages — this is typical for a single-stage planetary at this ratio. Maximum torsional backlash is 25 arc-minutes, which positions this as a general-purpose positioning gearbox rather than a zero-backlash servo-grade unit — acceptable for indexing and conveyor drives where the load holds position after stopping. Noise level is 58 dB at 1 m under no-load — a quiet-running unit suitable for indoor machinery where operator exposure is a concern.
Mounting and environmental fit
The 60 mm diameter black anodized aluminium housing mounts in any position, with IP54 protection at the shaft output — this keeps dust and splash ingress out but is not rated for washdown or submersion.
