Planetary gearbox with 16:1 reduction and 800 N.m continuous torque
The GBX1600160703F is a straight-tooth planetary gearbox from Schneider Electric's GBX series, with a 160 mm outer diameter and a 16:1 reduction ratio. It delivers 800 N.m continuous output torque at 100 rpm, with a maximum intermittent torque of 1280 N.m under the same conditions. Torsional backlash is held to 10 arcmin maximum, and the unit is rated for 30000 hours service life at rated load and 30 °C ambient.
The 800 N.m continuous torque figure is the sustained limit at 100 rpm and 30 °C — above that speed or temperature, derate accordingly. The 1280 N.m peak torque covers acceleration and emergency stops but not continuous duty. Backlash of 10 arcmin is typical for a straight-tooth planetary stage at this size; if the application needs tighter positioning (e.g., indexing or servo feed), a low-backlash or precision-geared stage would be needed. The 30000-hour service life at rated load assumes the gearbox is run at 100 rpm and 30 °C ambient. The lubricant is sealed for life — no oil changes, but the bearing and gear wear accumulate with load cycles.
Obsolete — sourcing the GBX1600160703F for legacy equipment
Schneider Electric lists this gearbox as obsolete. No direct successor order code is provided in the lifecycle record. For a line-down situation or a critical spare for an existing GBX-series install, the GBX1600160703F is available through independent surplus channels. Quantities are lot-specific and confirmed at RFQ — no stock-holding claim is made here.
Mechanical integration — shaft loads and environmental limits
The output shaft is C45 steel, and the housing is black anodized aluminium with a shaft-output IP54 rating — protected against dust ingress and splashing water, but not submersion or high-pressure washdown. Maximum axial force on the output shaft is 6000 N at 100 rpm for the 30000-hour life, or 8000 N for a 10000-hour life. Radial force limits are 4200 N (30000 h) and 6000 N (10000 h), measured at mid-distance from the shaft shoulder.
