12:1 planetary head with 260 N.m continuous — what the torque ratings mean
The GBX1200120703F is a straight-tooth planetary gearbox from the Schneider GBX series, 120 mm diameter, with a 12:1 reduction ratio. The continuous output torque is 260 N.m at 100 rpm and 30 °C, and the maximum output torque hits 416 N.m at the same speed and temperature — the higher figure is for intermittent peak loads, not sustained duty. Service life is rated at 30,000 hours at 100 rpm and 30 °C, and the unit ships lubricated for life — no oil changes in the field.
Sourcing reality — obsolete, sourced per RFQ
Schneider Electric lists the GBX1200120703F as obsolete. No official replacement or successor order code is recorded from the manufacturer.
Mounting and environmental fit
The gearbox has a 120 mm outer diameter black anodized aluminium housing, with a C45 steel output shaft. Shaft output sealing is rated IP54 — adequate for dry indoor environments but not for washdown. Ambient operating range is -25 to 90 °C. Maximum axial force on the output shaft is 2100 N at 100 rpm for the 30,000-hour life target, and 2800 N for a 10,000-hour duty. Maximum radial force is 1500 N and 2000 N respectively, measured at mid-distance from the output shaft.
