80 mm planetary — 9:1 reduction, 130 N.m continuous
The GBX0800090704F is a straight-tooth planetary gearbox from Schneider Electric's GBX series, with an 80 mm housing diameter and a 9:1 reduction ratio. It delivers 130 N.m continuous output torque at 100 rpm and 30 °C, with a maximum of 208 N.m available for peak loads. Efficiency is rated at 94 %, and the unit runs at 60 dB at 1 m under no-load conditions — quiet enough for most production floor environments.
Load ratings and service life at 100 rpm
Service life is 30,000 hours at 100 rpm and 30 °C, with the gearbox lubricated for life — no maintenance oil changes needed. Maximum axial force (Fa) is 1200 N at 100 rpm for a 10,000-hour life, dropping to 900 N for the full 30,000-hour rating. Maximum radial force (Fr) applied at mid-span on the output shaft is 950 N for 10,000 hours or 650 N for 30,000 hours at 100 rpm and 30 °C. Torsional rigidity is 6.5 N.m/arcmin, and maximum torsional backlash is 14 arc.min — a standard-precision grade for general positioning applications.
Construction and environmental sealing
Housing is black anodized aluminium; the output shaft is C45 steel. The shaft output seal carries IP54 protection, suitable for dry indoor environments with light dust or splash exposure. Ambient temperature range for operation is -25 to 90 °C, covering most industrial cabinet and machine-mount conditions.
