Planetary gearbox for precision motion control
The GBX1600201003F is a straight-tooth planetary gearbox from Schneider Electric's GBX series, with a 160 mm outer diameter and a 20:1 reduction ratio. It delivers a continuous output torque of 800 N.m at 100 rpm and can handle a maximum output torque of 1280 N.m under the same conditions. This gearbox is rated for a service life of 30,000 hours at 100 rpm and 30 °C, and is lubricated for life — no scheduled oil changes are needed in that window.
Torque, backlash, and load ratings
The continuous torque rating of 800 N.m at 100 rpm is the figure to size against for steady-state operation; the maximum torque of 1280 N.m covers peak loads during acceleration or momentary overloads. Both figures are stated at 30 °C ambient. Maximum torsional backlash is 10 arc.min — this sets the positioning repeatability floor for the driven axis. For applications requiring tighter indexing, a lower-backlash variant should be selected. Axial force capacity is 6000 N for the 30,000-hour service life, rising to 8000 N if a 10,000-hour life is acceptable. Radial force at mid-shaft is 4200 N for 30,000 hours, 6000 N for 10,000 hours. Both limits apply at 100 rpm and 30 °C.
Environmental and mechanical construction
The housing is black anodized aluminium, the shaft is C45 steel. The shaft output seal carries an IP54 rating — suitable for dry indoor environments but not washdown or outdoor exposure without additional shaft sealing. Noise level at 1 m, no-load, is 70 dB — typical for a planetary stage of this size. Efficiency is listed at 94 %, meaning about 6 % of input power is lost as heat in the gear train — a factor for thermal budgeting in the driven system.
Lifecycle and sourcing
Schneider Electric has classified the GBX1600201003F as obsolete. No official successor or cross-reference is recorded in the manufacturer's documentation. This gearbox is available through independent surplus and broker channels. Quantities are lot-specific and confirmed at RFQ. Full compliance documentation (RoHS, REACH, CE) is available from the original manufacturer's archive for the production batch.
