42GX-775 12V 100RPM 30Kg.cm Planetary DC Gear Motor

Exceptional Torque in a Compact Planetary Package

The 42GX-775 is a high-torque planetary DC gear motor delivering an impressive 30Kg.cm of torque at 100RPM on 12V. Built on the powerful 775-series motor with a precision planetary gearbox, it offers superior torque density and smooth, concentric power delivery compared to spur or rectangular gearbox alternatives.

Planetary gearboxes distribute load across multiple gear planets simultaneously, resulting in higher efficiency, lower backlash, and longer service life — making the 42GX-775 the right choice for demanding, load-bearing applications.
