MPLF90 Precision Planetary Gearbox

MPLF90 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.

MPLF90 / Gearboxes

Choose the ratio and stage together.

The MPLF90 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.

Mach will confirm your ordering part number, price and availability.

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.

MPLF90 only · Catalog rated output torque · Exact stage and listed ratio; duty, service factor and torque-rating input speed are not stated.

At 100:1, the catalog lists 54 N·m for two stages and 142 N·m for three stages. Ask Mach to confirm the rating against your speed, load cycle and required life.

Allow for the selected stage count.

Check catalog efficiency, weight and length together with the size outline. Confirm the final dimensions for the motor adapter you need.

The drawing uses L as a variable. It shows one generic outline for this size, rather than a separate stage-labeled assembly for every configuration.

Full specifications

Full specifications.

Review the published specifications below. Keep the size, stage, ratio and operating conditions with each value.

Confirm the selected backlash class and limit with Mach: the published table uses a strict less-than limit, while the catalog uses a less-than-or-equal limit.

Confirm the exact model and application-critical specifications with Mach.
