Helical gear unit
Helical gear units in a wide range of housing designs, with high-quality helical gearing and high torsional stiffness.

Helical gear units: The stylish classic

Are you looking for a compact, universally applicable helical gear unit? Made from one mold? Featuring high torsional stiffness? And high efficiency?

We recommend STOBER C series helical gear units.

BENEFITS
A beautiful form and absolutely reliable

STOBER helical gear units have an impressive design from a single mold, without any parting lines that can weaken them. This monoblock design is 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.

Due to the optimally designed helical toothing and the low-friction bearing, the efficiency of the helical gear units is very high.

Designed for tough continuous operation

The housing of our helical gear units is made of gray cast iron. The classic, proven mechanics allow these gear units to operate reliably even in harsh production environments and especially in continuous operation.

Compact helical gearing

C series helical gear units are compact and available in a wide range of housing designs – with pitch circle diameter, a round or square flange, or even with foot – so they are ideal for a wide for a wide range of applications.

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

C gear units are either available as directly attached, compact servo, Lean or asynchronous helical geared motors or they can be attached to all common synchronous servo motors by suitable adapters.
