Speed Reducer F Series Parallel Shaft Helical Gearbox

One of our best gear units for limited installation space. A wide range of mounting positions and variants enables a wide range of applications even under difficult installation conditions – without having to sacrifice performance. For many of our gear units: maintenance-free long service life and wear-free gears with high fatigue strength.

With high torque ratings from 130 Nm to 20,000 Nm, our parallel shaft helical gear reducers provide excellent performance in many conveying and processing applications.

You can choose from foot mount, flange mount, or shaft mount options. For precise positioning tasks, our parallel shaft helical gear units reduce backlash.

Then use our modular concept to combine a gearbox from the F series with an AC motor to form an F..DR.. parallel shaft gear motor, or with a servomotor to form an F..CMP parallel shaft helical servo gear motor of your choice. Or simply choose a split AC motor or servo motor that meets your requirements.
