Planetary gearbox, 12:1 reduction, 120 N.m continuous
The GBX0800120551F is a planetary gearbox with straight teeth, 80 mm outer diameter, and a 12:1 reduction ratio. It delivers 120 N.m continuous output torque at 100 rpm, with a maximum of 192 N.m under the same conditions. Rated efficiency is 94 %, and the torsional backlash is held to 14 arc.min maximum — tight enough for positioning axes where lost motion matters.
Sourcing reality — obsolete, quoted to order
Schneider Electric lists this gearbox as obsolete. We source it through independent distribution channels.
Mechanical ratings and deployment context
The housing is black anodized aluminium; the shaft is C45 steel. Shaft output sealing is IP54, so it handles dust and splash in a machine-tool or conveyor environment. Service life is 30,000 hours at 100 rpm and 30 °C ambient, with the gearbox lubricated for life — no maintenance interval for grease changes. Maximum axial force on the output shaft is 1200 N for 10,000 hours, derating to 900 N for the full 30,000-hour life. Radial force limits are 950 N (10,000 h) and 650 N (30,000 h), both measured at mid-span on the output shaft.
