Planetary gearbox — 80:1 reduction, 120 N.m continuous
The GBX0800801402F: This is a straight-tooth planetary gearbox with an 80:1 reduction ratio and a continuous output torque rating of 120 N.m (1062.09 lbf.in) at 100 rpm and 30 °C. The maximum output torque hits 192 N.m (1699.3 lbf.in) under the same conditions, so the gearbox can handle short overloads without damage — useful for indexing or start-up peaks on a conveyor or rotary table. Efficiency is listed at 94 %, which is typical for a single-stage planetary of this size. The 60 dB noise level at 1 m, no-load, is quiet enough for most production-floor environments — you won't need an acoustic enclosure for it in a standard machine cell.
Sizing and mounting — 80 mm diameter, IP54 shaft output
The gearbox has an 80 mm external diameter (3.1 in) and a black anodized aluminium housing. The shaft output carries an IP54 rating, which means it is protected against dust ingress and splashing water — fine for a dry indoor machine but not for washdown. The C 45 steel shaft handles maximum axial forces up to 1200 N (at 100 rpm, 10000 hours) and radial forces up to 950 N under the same duty cycle. Torsional rigidity is 6.3 N.m/arcmin, and the maximum backlash is 16 arc.min. That is a standard-precision grade — adequate for positioning axes with moderate accuracy requirements, but if your application needs tighter repeatability (under 5 arc.min), you would step up to a low-backlash or preloaded planetary.
Service life and lubrication — 30000 hours, lubricated for life
Rated service life is 30000 hours at 100 rpm and 30 °C. The gearbox is lubricated for life, so no maintenance schedule for oil changes — just mount it and run it until the end of its service interval.
