Round the corner with the right motor: Helical bevel gearboxes.

K gear units are very torsion-resistant helical bevel gear units featuring high-quality helical gearing. The series is available in three different classes, so you can adapt it perfectly to the application you need.

K gear units also have an impressive single-cast design and a wide range of housing designs.

The gear units are available either as compact servo, Lean or asynchronous helical bevel geared motors for direct attachment or they can be attached to all common synchronous servo motors by suitable adapters.

KL series helical bevel gear units are also manufactured from a single mold without any seams and are used primarily when applications call for high dynamics, low weight and, above all, a small installation space. This makes them ideal for the packaging industry.

KL gear units also have an impressive and extremely attractive price-performance ratio.

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

Thanks to the technology that provides robust bearings and high-quality gearing, the gear units of the KS series are extremely durable and tip-resistant.

They can be used in continuous operation without any problems – even at high speed levels. One of the most important features of the KS series is also its very high torsional stiffness.

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

Extended gear ratio range for a wide range of applications. STOBER has further developed its KS right-angle servo gearbox. In keeping with the motto „Power without Compromise“, it is now offered not only in two- and three-stage versions, but also in a one-stage version.
