Round the corner with the classic model: Power transmission helical bevel gearboxes.

STOBER helical bevel gearboxes are ideal when high performance, long service life and helical gearing for smooth operation are required.

This series is available in three different classes, so you can adapt it perfectly to the application you need.

K gearboxes also have an impressive single-cast design and a wide range of housing designs. The torsion-resistant monoblock design also has a favorable impact on the noise emission of the gearboxes. This is an major advantage for use in continuous operation!

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