Planetary gearbox, 160 mm frame, 12:1 single-stage reduction
The GBX1600121002F is a straight-tooth planetary gearbox from Schneider Electric's GBX series, with a 160 mm outer diameter housing and a 12:1 reduction ratio in a single planetary stage. Continuous output torque is 800 N.m (7080.6 lbf.in) at 100 rpm and 30 °C ambient, with a maximum intermittent torque of 1280 N.m (11328.9 lbf.in) under the same conditions — the continuous figure governs sizing for steady-duty conveyor or rotary-table drives. Efficiency is listed at 94 %, typical for a straight-tooth planetary at this ratio; the 10 arc-min maximum torsional backlash puts it in the standard-precision class, not low-backlash, so it fits positioning axes where a few arc-minutes of lost motion is acceptable.
Load ratings and service life at 100 rpm
Rated service life is 30000 hours at 100 rpm and 30 °C, with the gearbox lubricated for life — no oil-change interval to schedule, but the life figure assumes clean operation within the rated torque and ambient limits. Maximum axial force on the output shaft is 6000 N for the 30000-hour life target, or 8000 N if the application accepts a shorter 10000-hour life at the same speed and temperature. Maximum radial force is 4200 N for 30000-hour life and 6000 N for 10000-hour life, both measured with the force applied at mid-distance from the output shaft — mounting the driven load closer to the bearing reduces the effective radial load on the gearbox. The shaft output seal is rated IP54, meaning splash-resistant but not washdown; the gearbox is suited for indoor industrial environments with occasional coolant mist or dust, not for direct hose-down or outdoor exposure.
Construction and environmental range
Housing is black anodized aluminium (160 mm diameter), the output shaft is C45 carbon steel, and the gearset uses straight teeth — no helical angle, so the noise level at no-load is 70 dB measured at 1 m, which is audible but typical for this gearbox class.
Obsolete — sourced through independent channels
No direct drop-in replacement from Schneider exists — a new gearbox selection and mounting check are required for a redesign.
