16:1 reduction, 44 N.m continuous — the torque curve that governs the application
The GBX0600160703F is a 60 mm-diameter planetary gearbox from Schneider Electric's GBX series, delivering a 16:1 reduction ratio with a continuous output torque of 44 N.m at 100 rpm and 30 °C ambient. That 44 N.m continuous figure is the one to design against — the maximum output torque of 70 N.m is a short-duration peak, not a steady-state rating. Efficiency is listed at 94 %, meaning 6 % of the input power is lost as heat within the gearbox; for a 0.75 kW motor input, that is about 45 W of thermal load the housing must dissipate.
Backlash, service life, and the limits on overhung loads
Maximum torsional backlash is 20 arc.min — this is a standard-precision planetary, not a zero-backlash unit; if the application indexes position through the gear train, that 20 arc.min of lost motion at reversal must be accounted for in the positioning budget. Rated service life is 30,000 hours at 100 rpm and 30 °C, lubricated for life with no maintenance interval for grease changes. Maximum radial force on the output shaft is 340 N when the load is applied at mid-shaft distance, derated to 500 N for a 10,000-hour life; axial force limits are 450 N for the 30,000-hour target, 600 N for 10,000 hours. The shaft output seal carries an IP54 rating — protected against dust ingress and splashing water, but not immersion or high-pressure washdown.
Obsolete — sourcing through independent channels
Available through independent surplus and broker channels; quantities are lot-specific and confirmed at RFQ. The housing is black anodized aluminium, shaft material is C45 steel — standard for this class of planetary reducer.
