Your benefits

Low space requirement
due to a slim and compact design.

Wide range of applications
thanks to 11 frame sizes (27 to 157) and numerous variants for very different requirements.

Always a powerful performance
even in reduced backlash design with output torques from 200 Nm to 18,000 Nm.

R series helical gear units
F series parallel-shaft helical gear units: perfectly matched to limited installation space.

One of our best gear units for limited installation space. A wide range of mounting positions and variants enable a broad spectrum of applications even under difficult installation conditions – without having to compromise on the performance. And what applies to many of our gear units: long operating lives without maintenance and wear-free gearing with a high fatigue strength.

With a high torque rating from 130 Nm to 20,000 Nm, our parallel-shaft helical gear units offer great performance in many conveying and processing applications.

You can choose from foot-, flange- or shaft-mounted options. For precise positioning tasks, our parallel-shaft helical gear units are available with reduced backlash.

Only half the solution without a motor? Then use our modular concept and combine the gear units of the F series with an AC motor to a F..DR.. parallel-shaft gearmotor, or with a servomotor to an F..CMP parallel-shaft helical servo gearmotor of your choice. Or simply choose the separate AC motor or servomotor that meets your requirements.
