Planetary gearbox, 80 mm frame, 16:1 — now obsolete
The Schneider Electric GBX0800161002F is a straight-tooth planetary gearbox in the GBX series, 80 mm outer diameter, with a 16:1 reduction ratio. Rated for 120 N.m continuous output torque at 100 rpm and 30 °C, with a maximum intermittent torque of 192 N.m under the same conditions. Schneider has marked this part obsolete — no direct successor is listed in the available documentation.
Torque, backlash, and service life at 100 rpm
Continuous torque is 120 N.m (1062.09 lbf.in); peak torque reaches 192 N.m (1699.3 lbf.in) — both figures at 100 rpm and 30 °C ambient. Maximum torsional backlash is 14 arc.min, and torsional rigidity is 6.5 N.m/arcmin — the stiffness matters for positioning accuracy in indexing or pick-and-place applications. Rated service life is 30,000 hours at 100 rpm and 30 °C; the gearbox is lubricated for life with no maintenance interval.
Sourcing an obsolete GBX — what to expect
This GBX0800161002F is end-of-life per Schneider's lifecycle record. No official replacement part number has been published. Available through independent surplus and broker channels — quantities are lot-specific and confirmed at RFQ. No warranty from the original manufacturer applies. For a BOM freeze or a line-down replacement, a functional equivalent from the same frame size and ratio class would need to be qualified — the GBX series is closed.
Environmental and mechanical limits
Shaft output seal is rated IP54 — suitable for splash exposure but not pressurized washdown. Operating ambient range is -25 °C to 90 °C. Maximum axial force (Fa) is 1200 N at 100 rpm for 10,000 hours, derating to 900 N for the full 30,000-hour life. Radial force (Fr) at mid-shaft is 950 N (10,000 h) or 650 N (30,000 h). Noise level is 60 dB at 1 m under no-load conditions — quiet enough for most production-floor environments without an enclosure.
