Planetary gearbox, 32:1 — 120 N·m continuous, 14 arcmin backlash
The GBX0800321001F is a Schneider Electric planetary gearbox with straight teeth, 80 mm outer diameter, and a 32:1 reduction ratio. It delivers 120 N·m continuous output torque at 100 rpm and 30 °C, with a maximum of 192 N·m under the same conditions. Rated service life is 30,000 hours at 100 rpm and 30 °C, with the gearbox lubricated for life — no maintenance interval for grease changes in that window.
Load ratings and mechanical limits
Maximum axial force (Fa) is 1200 N for a 10,000-hour life at 100 rpm and 30 °C, derating to 900 N for the full 30,000-hour service life. Maximum radial force (Fr) applied at mid-distance on the output shaft is 950 N for 10,000 hours, dropping to 650 N for 30,000 hours. Torsional rigidity is 6.5 N·m/arcmin, and maximum torsional backlash is 14 arcmin — this defines the positioning repeatability for indexing or servo applications where lost motion matters. Efficiency is rated at 94 %, with noise level at 60 dB measured at 1 m, no-load. The housing is black anodized aluminium; the shaft is C45 steel. Ambient operating range is -25 to 90 °C. Shaft output protection is IP54 — suitable for indoor environments with dust and splash exposure, but not washdown or submersion.
Obsolete — sourcing through independent channels
Schneider Electric has marked the GBX0800321001F as obsolete. No direct successor or pin-compatible replacement is listed on the official record. Available through independent surplus and broker channels.
