What this 8:1 planetary gearbox delivers
The GBX0600080702F is a straight-tooth planetary gearbox from Schneider Electric's GBX series, 60 mm diameter, with an 8:1 reduction ratio. It delivers 18 N.m continuous output torque at 100 rpm and 30 °C, with a maximum of 29 N.m under the same conditions. Rated efficiency sits at 94 %, and the no-load noise level is 58 dB measured at 1 m — quiet enough for integration near operator stations without additional acoustic enclosures.
Lifecycle reality — obsolete, sourced through surplus
Schneider Electric lists this gearbox as obsolete. Stock is sourced through independent surplus and broker channels.
Mechanical limits that govern the fit
The black anodized aluminium housing carries a shaft output IP54 rating — suitable for dry indoor environments but not washdown. Shaft material is C45 steel. Service life is 30,000 hours at 100 rpm and 30 °C, with the gearbox lubricated for life — no maintenance schedule for grease changes. Maximum axial force on the output shaft is 450 N, and maximum radial force is 340 N, both at mid-shaft distance under the same 30,000-hour duty. Torsional backlash is 16 arc.min maximum, and torsional rigidity is 2.3 N.m/arcmin.
