12:1 planetary — 44 N.m continuous, 70 N.m peak
The GBX0600121001F is a 60 mm-diameter planetary gearbox with a 12:1 reduction ratio, delivering 44 N.m continuous output torque at 100 rpm and 30 °C ambient, with a peak rating of 70 N.m under the same conditions. Efficiency sits at 94 %, and the straight-tooth design keeps noise to 58 dB at 1 m under no-load — relevant for sound-sensitive production zones.
Lifecycle status — obsolete, sourced through surplus
The part is available through independent surplus and broker channels; quantities are lot-specific and confirmed at RFQ.
Mechanical limits — shaft loads and backlash
Maximum torsional backlash is 20 arc.min — budget this into positioning accuracy for indexing or pick-and-place applications. Rated axial force is 450 N for a 30,000-hour service life at 100 rpm and 30 °C, stepping to 600 N for a 10,000-hour duty cycle. Radial force at mid-shaft is 340 N for 30,000 hours, 500 N for 10,000 hours. Torsional rigidity is 2.5 N.m/arcmin — the stiffness figure matters when sizing the coupling to the motor shaft.
Build and environment — sealed, lubricated for life
Housing is black anodized aluminium; shaft material is C45 steel. The shaft output seal carries IP54 protection — suitable for dry indoor environments but not washdown. Operating ambient range is -25 to 90 °C. The gearbox is lubricated for life — no maintenance re-greasing interval.
