The GBX0800040704F is a Schneider Electric planetary gearbox with straight teeth, 80 mm housing diameter, and a 4:1 reduction ratio. Efficiency is listed at 94 %, which means 6 % of input power is lost as heat inside the gearbox. For a motor driving this reducer, the input power must be sized to cover that loss plus the output load. Service life is rated at 30,000 hours at 100 rpm and 30 °C ambient — a typical three-to-five-year continuous-run window before bearing or gear wear is expected. The gearbox is lubricated for life, so no oil-change interval applies.
Obsolete — sourcing through independent channels
Schneider Electric has marked the GBX0800040704F as obsolete. This part is available through independent surplus and broker channels. Quantities are lot-specific and confirmed at RFQ; no stock-holding claim is made here.
Mechanical limits that affect fit
Maximum axial force Fa is 1200 N for a 10,000-hour life and 900 N for the full 30,000-hour service life, both at 100 rpm and 30 °C. Maximum radial force Fr is 950 N (10,000 h) or 650 N (30,000 h), applied at mid-distance from the output shaft. Torsional rigidity is 6 N.m/arcmin, and maximum torsional backlash is 9 arcmin — this sets the positioning repeatability floor for the driven axis. The shaft output seal is rated IP54, meaning the gearbox is protected against dust ingress and splashing water at the working end, but not submersion. Shaft material is C45 steel; housing is black anodized aluminium. Ambient operating range is -25 to 90 °C.
