Planetary gearbox, 160 mm frame, 15:1 reduction
The GBX1600150703F is a straight-tooth planetary gearbox from Schneider Electric's GBX series, built in a 160 mm diameter housing. The 15:1 reduction ratio delivers 700 N.m continuous output torque at 100 rpm, with a peak of 1120 N.m available for transient loads. Efficiency sits at 94 %, and the maximum torsional backlash is held to 10 arc.min — tight enough for positioning axes where lost motion in the gear train would show up as repeatability error at the load.
Torque, load ratings, and service life at 100 rpm
Continuous output torque is 700 N.m (6195.5 lbf.in) at 100 rpm and 86 °F (30 °C), with a maximum output torque of 1120 N.m (9912.8 lbf.in) under the same conditions. The service life is rated at 30,000 hours at those figures — the gearbox is lubricated for life, so no oil-change interval to schedule. Maximum radial force Fr is 4200 N applied at mid-shaft for the 30,000-hour life, or 6000 N for a 10,000-hour duty cycle. Maximum axial force Fa is 6000 N for 30,000 hours, 8000 N for 10,000 hours. Torsional rigidity is 41 N.m/arcmin — the shaft wind-up under load is predictable and repeatable. The shaft output seal carries IP54 protection, meaning it resists dust ingress and splashing water — adequate for most enclosed drive trains but not washdown environments. Ambient operating range is -13 to 194 °F (-25 to 90 °C).
Sourcing reality — obsolete, quoted to order
Schneider Electric lists the GBX1600150703F as obsolete. The gearbox is available through independent distribution channels; quantities are confirmed at RFQ and sourced against the BOM line. The housing is black anodized aluminium, the shaft is C45 steel. Noise level is 70 dB at 1 m, no-load — a figure that rises under load but gives a baseline for comparing gearbox families.
