Planetary gearbox for motion axes — 20:1 reduction, 800 N.m continuous
The GBX1600200701F is a straight-tooth planetary gearbox from Schneider Electric's GBX series, 160 mm outer diameter, delivering a 20:1 reduction ratio. It is rated for 800 N.m continuous output torque at 100 rpm and 30 °C ambient, with a peak capability of 1280 N.m under the same conditions. The 94 % efficiency figure means roughly 6 % of input power is lost to friction and windage — typical for a single-stage planetary with straight teeth. At 100 rpm input, the output shaft turns at 5 rpm, so this gearbox is sized for low-speed, high-torque positioning axes on conveyors, rotary tables, or indexing drives.
Continuous output torque is 800 N.m at 100 rpm and 30 °C; the maximum intermittent torque reaches 1280 N.m at the same speed. The service life is rated at 30,000 hours at 100 rpm and 30 °C — if the duty cycle runs the gearbox hotter or faster, derate the life proportionally. Maximum axial force (Fa) on the output shaft is 6000 N for the full 30,000-hour life, or 8000 N if you accept a 10,000-hour service interval. Radial force (Fr) limits are 4200 N at mid-shaft for 30,000 hours, 6000 N for 10,000 hours. These are the constraints that govern bearing selection in the driven mechanism — exceed them and the output bearing wears out before the gear teeth. Torsional rigidity is 41 N.m/arcmin — the shaft twists 1 arcminute per 41 N.m of applied torque. Maximum torsional backlash is 10 arcminutes, which is standard precision for a straight-tooth planetary; if the application needs less than 5 arcmin, this gearbox is not the right fit.
Obsolete — sourcing reality and what replaces it
Schneider Electric lists the GBX1600200701F as obsolete. This means the part is no longer manufactured and is not available through standard Schneider distribution channels. The only supply path is through independent surplus and broker channels. Quantities are lot-specific — confirmed at RFQ against your BOM line. There is no pin-compatible or footprint-equivalent direct replacement from Schneider; a functional replacement would require evaluating a different gearbox series and possibly a mounting adapter.
Environmental and mechanical specs for integration
The housing is black anodized aluminium, the output shaft is C45 steel. Ambient operating range is -25 °C to 90 °C, which covers most indoor industrial environments but not outdoor freezing conditions without a heater. The shaft output seal is rated IP54 — splash-resistant but not washdown-rated. Noise level is 70 dB at 1 m under no-load — about the volume of a vacuum cleaner. In a quiet assembly area, this gearbox will be audible. The gearbox is lubricated for life, so no maintenance oil changes are needed.
