15:1 planetary gearbox — 44 N.m continuous, 70 N.m peak
The GBX0600150702F is a 60 mm diameter planetary gearbox from Schneider Electric's GBX series, delivering a 15:1 reduction ratio with straight-cut teeth. Continuous output torque is 44 N.m at 100 rpm and 30 °C, with a maximum intermittent torque of 70 N.m at the same speed and temperature. Efficiency is rated at 94 %, and the gearbox is lubricated for life — no scheduled re-greasing in the field. Service life is specified at 30,000 hours at rated load, speed, and ambient temperature.
Mechanical ratings that govern the fit
Maximum torsional backlash is 20 arc.min — this is the angular play at the output shaft when the input is locked. For positioning applications where reversal accuracy matters, this figure sets the repeatability floor; a servo-grade gearbox would be tighter, but for general indexing or conveyor drives this is within spec. Torsional rigidity is 2.5 N.m/arcmin — the stiffness of the gear train under load. The shaft output seal is rated IP54, meaning the gearbox is protected against dust ingress and splashing water, but not submersion or high-pressure washdown. Maximum radial force at the output shaft is 340 N for the 30,000-hour service life, or 500 N for a reduced 10,000-hour life. Axial force limits are 450 N (30,000 h) and 600 N (10,000 h). These are the load limits at the shaft midpoint — overhung loads or belt drives need to stay within these envelopes to avoid bearing fatigue. Ambient operating range is -25 to 90 °C. The housing is black anodized aluminium, and the shaft material is C45 carbon steel. Noise level is 58 dB at 1 m, no-load — quiet enough for indoor machinery without acoustic enclosures.
Obsolete — sourced through surplus channels
Schneider Electric has marked the GBX0600150702F as obsolete. The part is available through independent surplus and broker channels; quantities are lot-specific and confirmed at RFQ. For a BOM that requires this exact reduction ratio, diameter, and torque class, the GBX0600150702F is the only direct fit. A functional replacement would need to match the 60 mm housing diameter, 15:1 ratio, 44 N.m continuous torque, and the shaft output IP54 rating — any substitution requires a mechanical re-evaluation of the mounting interface and load envelope.
