Planetary gearbox with 8:1 reduction and 450 N.m continuous torque
The GBX1600080552F is a straight-tooth planetary gearbox from Schneider Electric's GBX series, with a 160 mm housing diameter and an 8:1 reduction ratio. The continuous output torque is 450 N.m at 100 rpm and 30 °C, with a maximum output torque of 720 N.m under the same conditions.
Torque, life, and force limits that govern the application
Rated service life is 30,000 hours at 100 rpm and 30 °C — the gearbox is lubricated for life, so no maintenance oil changes are needed over that interval. Maximum axial force on the output shaft is 6,000 N for the full 30,000-hour life, or 8,000 N if the application accepts a 10,000-hour service window. Maximum radial force applied at mid-span on the output shaft is 4,200 N for 30,000 hours, or 6,000 N for 10,000 hours. Torsional rigidity is 38 N.m/arcmin, and maximum torsional backlash is 6 arc.min — this positions the gearbox for indexing or positioning applications where repeatable accuracy matters, though not for zero-backlash servo duty. Efficiency is 94 %, which keeps thermal rise manageable in continuous operation. Noise level is 70 dB at 1 m under no-load conditions — a moderate figure for a planetary of this size; expect a few dB higher under full torque. The shaft output seal carries IP54 protection, meaning it resists dust ingress and splashing water, but not washdown or submersion.
Obsolete — sourcing through independent channels
Schneider Electric lists the GBX1600080552F as obsolete. The part is sourced through independent surplus and broker channels, with availability and pricing confirmed at RFQ against the specific BOM quantity.
