Planetary gearbox for precision motion — 32:1 reduction, 44 N.m continuous torque
The GBX0600321004F is a straight-tooth planetary gearbox from Schneider Electric's GBX series, delivering a 32:1 reduction ratio with 44 N.m continuous output torque at 100 rpm. Rated efficiency hits 94 %, and the service life is spec'd at 30000 hours at 100 rpm and 30 °C — the gearbox is lubricated for life, so no maintenance interval on the oil change. Noise measures 58 dB at 1 m under no-load — quiet enough for lab or light industrial environments where operator exposure matters.
Obsolete — sourcing through independent channels
Schneider Electric lists the GBX0600321004F as obsolete — no official successor part number is published. This unit is sourced through independent surplus and broker channels. Quantities are confirmed at RFQ; no stock-holding claim is made here.
Mechanical envelope and load limits
Housing is black anodized aluminium, 60 mm external diameter, with a C45 steel output shaft. Shaft output seal is rated IP54 — splash-resistant but not submersible. Ambient operating range spans -25 to 90 °C. Maximum axial force on the output shaft is 450 N for the 30000-hour life target, or 600 N if you accept a 10000-hour service window. Radial force limits are 340 N (30000 h) and 500 N (10000 h), measured at mid-shaft. Torsional backlash is 20 arcmin maximum; torsional rigidity is 2.5 N.m/arcmin — relevant for positioning accuracy in indexing or pick-and-place axes.
