Helical Planetary Gearboxes

Explore MKB, MKL, MKS, MKT, MZS and MZF planetary gearbox series. Use the series pages to compare size-specific performance, mounting dimensions and motor connections.

Helical High Precision Planetary / Gearboxes

Start with the series and mechanical fit.

Choose a series, then compare the required ratio and loads against its size-specific performance data. Use the matching dimensional drawing to check the output connection, motor interface and available installation space.

MKB

MKB Series

MKB catalog drawings show a square output-side mounting face. Compare the size-specific shaft, mounting and motor-interface dimensions.

MKL

MKL Series

MKL catalog drawings show a circular output-side mounting face. Check the required size and its motor-interface drawing.

MKS

MKS Series

MKS ordering guidance includes keyed and smooth output shafts. Match the output arrangement and motor interface to the selected size.

MKT

MKT Series

MKT catalog drawings show a flange-style output. Check the dimensioned interface for the selected size and confirm its complete ordering code with Mach.

MZS

MZS series

The MZS catalog shows a projecting keyed output shaft. Compare its size-specific torque data and mounting dimensions.

MZF

MZF series

Review the flange-style output shown in MZF drawings and compare its mounting dimensions with your driven equipment.

Compare the exact size, ratio and stage configuration. A series-wide maximum is not a rating for every configuration.

Your application

Send the details that determine the selection.

Send your motor datasheet, target ratio or output speed, continuous and peak output torque, duty cycle, load arrangement and available mounting space. Include the series and size you are considering so Mach can confirm the configuration.

Output and duty
Required output speed and torque, including acceleration, peak events and the duty cycle
Motor interface
Motor make and exact model, speed, shaft diameter and length, pilot and mounting dimensions
Shaft loading
Radial and axial loads, where they act on the output, and the proposed coupling, belt, pinion or other connection
Precision and installation
Positioning or backlash requirement, mounting space, ambient conditions and operating orientation
