The GBX0800120703D: For volume BOM commitments, this planetary gearbox is quoted to order against the line-item quantity — availability and pricing confirmed at RFQ time.
Torque and reduction — sizing the drive train
With a 12:1 reduction ratio and 120 N.m continuous output torque (192 N.m maximum), this gearbox matches servo or stepper motor outputs in the 10–15 N.m input range, typical for indexing tables or conveyor drives. The 94 % efficiency means only 6 % of input power is lost as heat — important for duty cycles where thermal buildup in a confined enclosure matters. Torsional rigidity of 6.5 N.m/arcmin keeps windup low under reversing loads, and the 17 arc-min maximum backlash suits positioning applications where repeatability is tighter than a few tenths of a degree.
Mounting and environmental fit
The 80 mm-diameter black anodised aluminium housing mounts in any position, and the C 45 steel output shaft handles axial loads up to 1200 N and radial loads up to 650 N at 100 rpm (derated for 30000-hour life). IP54 at the shaft output means it resists dust and splashing water — fine for dry indoor machine builds but not washdown zones. Rated for -25 to 90 °C ambient, lubricated for life, and noise is a quiet 60 dB at 1 m no-load — no periodic oil changes needed.
