Your advantages

Reduce operating costs
because the helical-bevel gearmotors are virtually wear-free and low-maintenance. This allows you to effectively reduce costs during operation.

High power rating
as the gearmotors have a torque of up to 50,000 Nm.

Save energy
Thanks to their high efficiency, our helical-bevel gearmotors are also real energy savers.

Helical-bevel gearmotors: low maintenance and high efficiency

Are you looking for a low-maintenance and largely wear-free but high-torque drive solution? Then our helical-bevel gearmotors K..DR.. are the right choice. Because we offer you gear units and motors combined as compact drive components: perfectly matched to each other and to your application.

The design of our bevel gearboxes makes them particularly robust and low-maintenance. The reason for this is the durable gearing and the quality of workmanship of all components. If you combine this bevel gearbox with an AC motor, you get a powerful and compact helical-bevel gearmotorwith a high efficiency and, depending on the required efficiency class, with a motor power range of up to 200 kW.

No matter what application you want to realise, the possible combinations of K..DR.. bevel gearboxes are diverse: large gear ratio range, foot or flange-mounted designs for flexible installation and motor variants for efficiency classes from IE1 to IE4.

Save time and money

By choosing one of our gearmotors, you save time and money right from the selection and dimensioning stage. This is because our modular system enables a wide range of combinations of gear units and motors. This allows you to reduce operating costs, build on a long service life and benefit from our brand-typical maintainability.
