120 mm planetary gearbox — 5:1 reduction, 195 N.m continuous
The GBX1200050701F is a 120 mm diameter planetary gearbox with straight-cut teeth, delivering a 5:1 reduction ratio. Continuous output torque is 195 N.m at 100 rpm and 30 °C; maximum intermittent torque reaches 312 N.m under the same conditions. Rated service life is 30,000 hours at 100 rpm and 30 °C, with the unit lubricated for life — no maintenance schedule for oil changes. Maximum torsional backlash is 8 arc.min, suitable for positioning applications that don't require zero-backlash precision.
Load ratings and mechanical limits
Maximum axial force (Fa) on the output shaft is 2100 N for the full 30,000-hour service life at 100 rpm and 30 °C; this can be increased to 2800 N if the application accepts a reduced 10,000-hour life. Maximum radial force (Fr), applied at mid-distance from the output shaft, is 1500 N for 30,000 hours or 2000 N for 10,000 hours. Torsional rigidity is 12 N.m/arcmin, giving a stiffness figure for calculating windup under load. The shaft output carries an IP54 ingress protection rating — sealed against dust and splashing water at the output side, but the gearbox body itself is not fully sealed. Noise level is 65 dB at 1 m under no-load conditions.
Sourcing — obsolete, quoted to order
Schneider Electric lists the GBX1200050701F as obsolete. No direct successor order code is recorded on the lifecycle entry. Efficiency is listed at 94 %, which is typical for a single-stage planetary of this ratio. The 65 dB noise figure at 1 m no-load gives a baseline for acoustic comparison in the application envelope.
