Planetary gearbox for precision motion — 40:1 reduction, 40 N.m continuous
The GBX0600401403F is a 60 mm-diameter planetary gearbox from Schneider Electric, built for servo or stepper motor output stages where a 40:1 reduction and 40 N.m continuous torque at 100 rpm are needed. Straight-tooth gearing keeps the efficiency at 94 % and the no-load noise at 55 dB at 1 m — a reasonable acoustic footprint for a machine-tool or packaging-line axis. The 40 N.m continuous rating is the number to size against; the maximum output torque of 64 N.m at 100 rpm is a short-term peak, not a duty-cycle figure.
Lifecycle status — obsolete, sourced through independent channels
This gearbox is available through independent surplus and broker distribution. If a drop-in replacement is needed, the closest functional match would be a 60 mm planetary gearbox with the same 40:1 ratio and comparable torque — but the mounting flange and input bore must be verified against the existing motor interface.
Service life and mechanical limits — 30,000 hours at rated load
Rated service life is 30,000 hours at 100 rpm and 30 °C ambient, with the gearbox lubricated for life — no maintenance re-greasing interval. Maximum axial force on the output shaft is 450 N for the full 30,000-hour life, or 600 N if the application accepts a 10,000-hour service window. Radial force limits are 340 N and 500 N respectively, measured at mid-shaft. Torsional rigidity is 2.5 N.m/arcmin, and maximum torsional backlash is 20 arc.min — relevant for positioning accuracy in indexing or point-to-point moves.
