80 mm planetary stage — 100:1 reduction, 120 N.m continuous
The GBX0801001001F is a straight-tooth planetary gearbox from Schneider Electric's GBX series, 80 mm outer diameter, delivering a 100:1 reduction ratio. Continuous output torque is 120 N.m at 100 rpm and 30 °C, with a maximum intermittent torque of 192 N.m at the same speed and temperature. Efficiency is rated at 94 %, and the torsional rigidity is 6.3 N.m/arcmin — the stiffness figure that governs positioning accuracy under load in servo or stepper applications. The housing is black anodized aluminium; the output shaft is C45 steel. Shaft-output sealing is IP54, meaning the gearbox is splash-resistant at the shaft exit but not submersible.
Lifecycle status — obsolete, sourced against RFQ
Schneider Electric has marked the GBX0801001001F as obsolete. This gearbox is sourced through independent distribution channels.
Load ratings and service life — what the numbers mean for fit
Service life is 30,000 hours at 100 rpm and 30 °C. The gearbox is lubricated for life — no oil-change interval to schedule. Maximum axial force on the output shaft is 1200 N for a 10,000-hour life at 30 °C, derating to 900 N for the full 30,000-hour service life. Maximum radial force applied at mid-shaft is 950 N (10,000 h) or 650 N (30,000 h). These are the load limits that determine bearing life in overhung or thrust-loaded applications. Maximum torsional backlash is 16 arcmin — this is the angular play at the output under reversing load, relevant for positioning accuracy in indexing or pick-and-place axes.
