What this 40:1 planetary gearbox delivers
The GBX0600401003F is a 60 mm-diameter planetary gearbox with straight teeth and a 40:1 reduction ratio, rated for 40 N.m continuous output torque at 100 rpm and 30 °C (86 °F). Efficiency is listed at 94 % — a meaningful figure for long-run applications where every percentage point of loss compounds into heat and energy cost.
Backlash, noise, and service life — what they mean for fit
Maximum torsional backlash is 20 arc.min — this is a standard-precision class, not a zero-backlash unit, so it suits positioning where the cumulative error from gear train and motor encoder can be absorbed by the controller's backlash compensation or where the load doesn't reverse direction frequently. Noise level is 55 dB at 1 m, no-load — quiet enough for a production floor near operators without hearing protection, though the actual level under load depends on the motor and mounting stiffness. Service life is 30,000 hours at 100 rpm and 30 °C — roughly 3.4 years of continuous running. The gearbox is lubricated for life, so no maintenance interval for oil changes.
Sourcing and lifecycle reality
Available through independent surplus and broker channels; quantities are lot-specific and confirmed at RFQ. No pin-compatible direct replacement from the same family is documented, so a BOM revision or alternative gearbox selection may be required.
