80 mm planetary, 80:1 reduction, 120 N.m continuous
The GBX0800801004F is a Schneider Electric planetary gearbox with straight-cut teeth, 80 mm housing diameter, and an 80:1 reduction ratio. It delivers 120 N.m continuous output torque at 100 rpm and 30 °C, with a maximum intermittent torque of 192 N.m under the same conditions. Rated service life is 30,000 hours at 100 rpm and 30 °C, and the unit is lubricated for life — no maintenance oil changes required over that interval. Torsional backlash is 16 arc.min maximum, and torsional rigidity is 6.3 N.m/arcmin — the stiffness figure tells you how much wind-up to expect under load, which matters for positioning accuracy in indexing or servo-follower applications.
Load ratings and overhung limits
Maximum radial force (Fr) applied at mid-distance from the output shaft is 650 N for the full 30,000-hour service life at 100 rpm and 30 °C, or 950 N if you accept a 10,000-hour life. Maximum axial force (Fa) is 900 N for 30,000 hours, or 1,200 N for 10,000 hours. These are the bearing load limits — exceeding them shortens gearbox life faster than torque overload. The IP54 rating on the shaft output means the seal keeps out dust and splash, but it is not rated for washdown or submerged service. Efficiency is 94 %, which is typical for a single-stage planetary with straight teeth at this ratio. Noise level is 60 dB at 1 m, no-load — audible but not loud enough to require enclosure damping in most machine builds.
Obsolete — sourcing through independent channels
Schneider Electric lists the GBX0800801004F as obsolete. For a buyer with this on a BOM line, the practical path is sourcing through independent distribution — new-old-stock or surplus lots. The housing is black anodized aluminium, shaft material is C45 steel, and the operating ambient range is -25 to 90 °C. If your application runs outside that temperature band or requires a higher IP rating, this unit will not fit without additional enclosure protection.
