A helical gear unit with high torsional stiffness combined with an extremely compact, highly dynamic STOBER synchronous servo motor.

The stylish classic with the powerhouse: Helical servo geared motors.

Are you looking for a compact, universally applicable helical geared motor? Something attractive? With helical gearing? Highly dynamic?

We have it! STOBER is an experienced manufacturer of helical servo geared motors and supplies well-known customers throughout the world of automation.

BENEFITS

STOBER helical gear units have an impressive block design, without any parting lines that can weaken them. They are an absolute advantage in terms of rigidity and leak-proofness! And they score points for their appearance at the same time.

A characteristic feature of these gear units are the coaxial axes.
The ideal design of the helical toothing and low-friction bearing makes their efficiency impressively high.

The classic, proven mechanics of STOBER helical gear units combined with a powerful EZ motor – the reliable, dynamic jack-of-all-trades for continuous operation.

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

Helical servo geared motors: The helical gear units themselves are compact and available in a wide variety of housing designs – with a pitch circle diameter, a round or square flange, or even with a foot – so they are ideal for a wide range of applications.

The helical gearing that is typical of STOBER and resulting exceptionally smooth operation are also remarkable.

STOBER Helical servo geared motors: Connected directly to an EZ motor, the result is a very compact and exceptionally dynamic synchronous servo geared motor with high torsional stiffness and high volume performance.
