80 mm planetary gearbox — 16:1 ratio, 120 N.m continuous
The Schneider Electric GBX0800161101G is a planetary gearbox with straight teeth, 80 mm outer diameter, and a 16:1 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. Efficiency is rated at 94 %, and the gearbox runs at 60 dB at 1 m under no-load — quiet enough for most production-floor installations without additional acoustic enclosures.
Torque, backlash, and service life at 30 °C
Maximum torsional backlash is 14 arc.min — this is a standard-precision planetary, not a zero-backlash unit, so factor it into positioning accuracy budgets for indexing or pick-and-place axes. Service life is 30,000 hours at 100 rpm and 30 °C, lubricated for life with no maintenance interval. Torsional rigidity is 6.5 N.m/arcmin, giving predictable deflection under load. Maximum radial force (Fr) at the output shaft mid-point is 650 N for 30,000-hour life, or 950 N for 10,000-hour life at 100 rpm. Maximum axial force (Fa) is 1200 N for 10,000 hours, derating to 900 N for 30,000 hours.
Mounting, sealing, and environmental range
Mounts in any position — no oil-breather orientation constraints. The housing is black anodized aluminium; the output shaft is C45 steel. Shaft output sealing is IP54, suitable for dry indoor environments but not washdown or outdoor exposure. Moment of inertia is 0.5 g.cm², low enough for servo applications with frequent start-stop cycles.
Obsolete — sourced through independent channels
Schneider Electric lists the GBX0800161101G as obsolete. No official successor or cross-reference is recorded from the manufacturer. Available through independent surplus and broker channels. Quantities are lot-specific — confirmed at RFQ. No pin-compatible or direct drop-in replacement from Schneider is documented.
