Planetary gearbox, 80 mm frame, 8:1 reduction
The GBX0800081401F is a straight-tooth planetary gearbox from Schneider Electric's GBX series, with an 80 mm housing diameter and an 8:1 reduction ratio. It delivers 50 N.m continuous output torque at 100 rpm and 30 °C, with a maximum intermittent rating of 80 N.m under the same conditions. Efficiency is listed at 94 %, and the gearbox is lubricated for life — no maintenance oil changes over its 30,000-hour service life at rated load.
Load ratings and mechanical limits
Maximum radial force Fr is 650 N at mid-shaft, sustained over 30,000 hours at 30 °C; the same load can be increased to 950 N if the service life target is reduced to 10,000 hours. Maximum axial force Fa is 1200 N for a 10,000-hour life, derated to 900 N for the full 30,000-hour window. Torsional rigidity is 6 N.m/arcmin, and maximum torsional backlash is 9 arc.min — the positioning repeatability floor for indexing or pick-and-place applications driven through this box. The housing is black anodized aluminium; the output shaft is C45 steel. Shaft output seal is rated IP54, so the gearbox is splash-resistant but not suitable for pressurized washdown.
Lifecycle — obsolete, sourced to order
Schneider Electric lists the GBX0800081401F as obsolete. Available through independent surplus and NOS channels. No pin-compatible drop-in replacement from the current GBX catalog is documented.
