16:1 planetary reduction, 44 N.m continuous
The GBX0600160704F 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. The maximum output torque reaches 70 N.m under the same conditions, giving a 1.6× overload margin for transient loads like acceleration or reversing. Rated efficiency is 94 %, meaning roughly 6 % of input power is lost as heat through the gear mesh — a figure that holds across the rated speed range for a straight-tooth planetary stage. The torsional rigidity of 2.5 N.m/arcmin keeps positioning error under load predictable for indexing or pick-and-place axes.
Load ratings and service life
Service life is specified at 30,000 hours at 100 rpm and 30 °C, with the gearbox lubricated for life — no maintenance interval for oil changes. The 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 shorter 10,000-hour service window. Radial force limits follow the same pattern: 340 N at mid-shaft for 30,000 hours, 500 N for 10,000 hours. Maximum torsional backlash is 20 arc.min — a standard-precision grade for general motion control, not a zero-backlash stage. The shaft output carries an IP54 rating, meaning the output seal resists dust ingress and splashing water, suitable for washdown-adjacent environments but not submerged or high-pressure spray.
Obsolete — sourcing through independent channels
Schneider Electric has classified the GBX0600160704F as obsolete. The part is available through independent surplus and broker channels; quantities are lot-specific and confirmed at RFQ. For a BOM line that depends on this gearbox, the practical path is to source remaining stock against the RFQ while evaluating a parametric replacement. The 60 mm housing diameter, 16:1 ratio, and 44 N.m continuous torque are the binding constraints for a drop-in alternative.
