Planetary gearbox for precision motion
The GBX0800251402F is a straight-tooth planetary gearbox from Schneider Electric's GBX series, sized for servo and stepper motor applications that need a compact 80 mm diameter package with a 25:1 reduction ratio. Continuous output torque is 110 N.m at 100 rpm and 30 °C, with a maximum intermittent torque of 176 N.m — the higher figure is for acceleration peaks, not sustained duty. Efficiency is listed at 94 %, which is typical for a single-stage planetary with straight teeth; the 14 arcmin maximum torsional backlash means this is a standard-precision unit, not a low-backlash stage for contouring axes.
Mechanical ratings and service life
Rated service life is 30,000 hours at 100 rpm and 30 °C — the gearbox is lubricated for life, so no maintenance interval for oil changes. Maximum axial force on the output shaft is 1200 N for a 10,000-hour life, derating to 900 N for the full 30,000-hour target; radial force at mid-span is 950 N for 10,000 hours or 650 N for 30,000 hours. The output shaft is C45 steel, the housing is black anodized aluminium, and the shaft output seal carries IP54 protection — suitable for dry indoor environments but not washdown.
