Power transmission helical gear units
Rugged power transmission variant of STOBER helical gear units with high-quality helical gearing.

The stylish classic unit for the long haul: Power transmission helical gear units.

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

We recommend our power transmission helical gear units! With our short STOBER adapters, they can be quickly and easily attached to all common asynchronous motors.

BENEFITS
Designed for tough continuous operation

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 torsional stiffness and leak-proofness!

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

Another characteristic feature of helical gear units are the coaxial axes. The helical gearing and resulting exceptionally smooth operation are also remarkable. It’s perfect for continuous operation.

Using a short motor adapter, the helical gear units can be attached to standard or stainless steel motors quickly and easily in accordance with IEC or NEMA-C.
