Planetary gearbox, 80 mm, 25:1
The GBX0800250554F is a planetary gearbox from Schneider Electric's GBX series, 80 mm external diameter, straight-tooth design, with a reduction ratio of 25:1. Continuous output torque is 110 N.m at 100 rpm and 30 °C; maximum output torque reaches 176 N.m under the same conditions. Torsional rigidity is 6.5 N.m/arcmin, with maximum torsional backlash at 14 arc.min.
Efficiency, noise, and service life
Rated 94 % efficiency across the operating range — losses are low enough that the gearbox runs cool in continuous duty. Noise level is 60 dB at 1 m, no-load, which is quiet for a straight-tooth planetary stage. Service life is 30,000 hours at 100 rpm and 30 °C. The unit is lubricated for life — no oil changes, no maintenance interval for the grease fill. Ambient temperature range for operation is -25 to 90 °C. Shaft output seal is rated IP54, so it handles dust and splash in a clean industrial environment.
Obsolete — sourcing the GBX0800250554F
Schneider Electric lists this gearbox as obsolete. The shaft material is C 45 steel; housing is black anodized aluminium. The unit ships one per package.
