Planetary gearbox, 40:1 reduction, 700 N.m continuous
The GBX1600400702F is a 160 mm planetary gearbox from Schneider Electric's GBX series, delivering a 40:1 reduction ratio with straight-cut teeth. Continuous output torque is 700 N.m at 100 rpm, with a maximum intermittent rating of 1120 N.m at the same speed. Efficiency sits at 94 %, and maximum torsional backlash is held to 10 arcmin — tight enough for positioning axes where lost motion matters. Service life is rated 30,000 hours at 100 rpm and 30 °C ambient.
Load ratings and mechanical limits
Maximum axial force Fa is 6000 N at 100 rpm over the 30,000-hour service life, or 8000 N for a 10,000-hour duty cycle. Maximum radial force Fr at mid-shaft is 4200 N for the 30,000-hour rating, stepping to 6000 N for the shorter 10,000-hour window. Torsional rigidity is 41 N.m/arcmin — the shaft stiffness that governs windup under load. The housing is black anodized aluminium with a C45 steel output shaft, and the shaft output seal carries IP54 protection. Operating ambient temperature spans -25 to 90 °C. The unit is lubricated for life, with a noise level of 70 dB at 1 m under no-load conditions.
Lifecycle — obsolete, sourced through independent channels
Schneider Electric has marked the GBX1600400702F as obsolete. No official successor or cross-reference is recorded from the original manufacturer. Available through independent surplus and broker channels. Quantities are lot-specific — confirmed at RFQ against the BOM line.
