MPLF120 Precision Planetary Gearbox

MPLF120 precision planetary reducer with catalog ratings for one-, two- and three-stage configurations. Compare rated torque at your ratio, allow for stage-dependent length and check the shaft and flange drawing before specifying a motor.

MPLF120 / Gearboxes

Choose the ratio and stage together.

The MPLF120 catalog gives discrete ratios for each stage count. The same ratio can appear in more than one stage, so ratio alone does not identify the torque rating or package length.

Motor and shaft fit

Check the actual flange drawing.

The catalog describes a straight-tooth design with standard or custom motor mounts. NEMA compatibility is available on request; confirm the motor interface and any custom shaft features with Mach.

Size names are catalog identities, not complete ordering part numbers. Send the required ratio, stage and motor drawing when requesting a selection.

Compare the rated torque at your ratio.

Ratios with the same rated torque are grouped within each stage. Each listed ratio remains a separate catalog configuration.
