APEX AB142-S1-P1 High Precision Planetary Gearbox

APEX AB142-S1-P1 High Precision Planetary Gearbox is a compact, in-line servo reducer from Apex Dynamics’ AB-series, designed for continuous (S1) operation with a 4:1 reduction. It targets servo applications, delivering high-precision torque transmission with low backlash and high efficiency in a small footprint. The AB142‑S1‑P1 suffix indicates its continuous-duty service rating and standard output-shaft configuration used across AB-series models. In-line AB gearboxes in this family typically offer very low backlash, with P1 backlash as low as ≤3 arcmin for ratios in the 3:1–10:1 band (and ≤5 arcmin for higher ratios), and output torque ratings commonly listed around 342–650 Nm for AB142 configurations.
