Your benefits

Reduced operating costs
as the helical-bevel gearmotors are nearly wear-free and low-maintenance. In this way, you effectively reduce costs in operation.

High performance
as the gearmotors have a torque of up to 50 000 Nm.

Save energy
thanks to their high efficiency, our helical-bevel gearmotors are 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 you are making the right decision with our helical-bevel gearmotors K..DR.. This is because we offer you gear units and motors combined as compact drive components: perfectly in tune with each other and adapted to your application.

Due to their design, our helical-bevel gear units are especially robust and low-maintenance. The reason for this is the high-endurance gearing and the high manufacturing quality of all component parts. Combine this helical-bevel gear unit with an AC motor and you get a powerful and compact helical-bevel gearmotor: with high efficiency and, depending on the energy efficiency class required, with a motor power range of up to 200 kW.

Irrespective of the application you wish to implement, the combination options for helical-bevel gear units K..DR.. are diverse: wide range of gear unit ratios, foot or flange-mounted design for flexible installation and motor variants for energy efficiency classes IE1 to IE4.

Save time and money

By opting for one of our gearmotors, you are already saving time and money with this selection and project planning. This is because our modular system enables a multitude of combination options for gear units and motors. You can therefore reduce operating costs, count on a long service life and benefit from simplified maintenance that is characteristic of our brand.
