Planetary gearbox, 40 mm, 8:1 reduction
The Schneider Electric GBX0400081002F is a planetary gearbox with straight teeth, 40 mm external diameter, and an 8:1 reduction ratio. It delivers a continuous output torque of 6 Nm at 100 rpm and 30 °C, with a maximum output torque of 10 Nm under the same conditions. Efficiency is listed at 94 %, and the gearbox is lubricated for life, eliminating the need for periodic oil changes in service.
Rated load and service life at speed
Service life is rated at 30,000 hours at 100 rpm and 30 °C. At this duty point, the maximum axial force (Fa) is 160 N and the maximum radial force (Fr) is 160 N, applied at mid-distance from the output shaft. For a 10,000-hour service life target, both axial and radial limits increase to 200 N. Torsional rigidity is 1 N·m/arcmin, and maximum torsional backlash is 30 arcmin — this backlash figure is the total angular play under reversing load, relevant for positioning accuracy in indexing applications. The ambient temperature range for operation is -25 °C to 90 °C, and the shaft output seal is rated IP54, meaning it is protected against dust ingress and splashing water from any direction.
