Offset helical servo geared motors

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

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

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

These gearboxes 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!

Do you design gravity-loaded axes? Learn more about our offset helical geared motors with redundant brake.

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

The hardened helical gearing ensures reliable backlash stability.

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