Planetary gearbox, 32:1 reduction, 800 N.m continuous
The GBX1600320551F is a straight-tooth planetary gearbox from Schneider Electric's GBX series, with a 160 mm outer diameter and a 32:1 reduction ratio. Continuous output torque is 800 N.m at 100 rpm and 30 °C; peak torque reaches 1280 N.m under the same conditions — that's the overload ceiling before the gear train yields. Efficiency is 94 %, which keeps thermal rise manageable in continuous-duty servo or conveyor applications. Backlash is held to 10 arcmin maximum — adequate for positioning axes that don't need zero-backlash preloading.
Load ratings and service life
Rated service life is 30,000 hours at 100 rpm and 30 °C, with the gearbox lubricated for life — no oil changes, no breather maintenance. Maximum axial force on the output shaft is 6000 N for the full 30,000-hour life, or 8000 N if you accept a 10,000-hour service window. Radial force limits are 4200 N (30,000 h) and 6000 N (10,000 h), measured at mid-shaft. Torsional rigidity is 41 N.m/arcmin — the shaft wind-up under load is predictable, so the stiffness figure feeds directly into servo tuning and position-error budgeting.
Environmental and mechanical specs
Ambient operating range is -25 to 90 °C, covering most indoor industrial enclosures without derating. The shaft output seal carries IP54 protection — fine for dry or dusty environments, but not washdown.
Sourcing — obsolete, quoted to order
