Planetary gearbox, 40 mm frame, 3:1 ratio
The GBX0400031004F is a 40 mm-diameter planetary gearbox from Schneider Electric's GBX series, offering a 3:1 reduction ratio with straight-cut teeth and a rated efficiency of 94 %. Rated for 30,000 hours service life at 100 rpm and 30 °C ambient, it is lubricated for life and sealed — no maintenance access required in the field.
Load capacity and backlash limits
Maximum axial force is 200 N at 100 rpm for a 10,000-hour life, derating to 160 N for the full 30,000-hour rating; radial force follows the same profile when applied at mid-span on the output shaft. Maximum torsional backlash is 24 arcmin — this is a standard-precision gearbox, not a zero-backlash stage; the torsional rigidity is 1 N·m/arcmin.
