Offset helical servo geared motors
A precise STOBER servo gear unit with a flat housing and large axial distance – combined with an extremely compact, highly dynamic synchronous servo motor from STOBER.

Offset helical servo geared motors: The slim black wonder with a powerhouse

Looking for a geared motor for small installation spaces? With a large axial distance? High positioning accuracy? And absolutely powerful at the same time?
Voilà: Here are the STOBER offset helical servo geared motors.

BENEFITS
Offset helical gear unit feat. EZ motor

Due to their extremely flat housing and large axial distance, offset helical gear units are easy to integrate in applications that have very tight, difficult space constraints.

These gear units also meet high demands for efficiency, ruggedness and a long service life.

When it is directly attached to an EZ motor, you benefit from an even smaller installation space, lower weight and high torque at the same time!

High positioning accuracy and backlash stability

To meet higher precision requirements, the F series offset helical gear units are available in two backlash classes.

The hardened helical gearing ensures reliable backlash stability.

F and EZ – thanks to the short design of the gear unit and motor, this combination gives you a geared motor that is extremely compact, precise, dynamic and highly reliable.
