Thanks to their long maintenance-free operating life and their wear-free gearing, our helical-bevel gear units are – technically speaking – economical right-angle gear units. Their high level of efficiency, however, makes them real energy savers.
Right-angle gear units at their best: high degree of efficiency and gearing with high fatigue strength
The compact design of all our gear units is most obvious in our helical-bevel gear units. This property is particularly interesting, for example, for machine applications with limited space available. Here, you need powerful drive technology with a compact design. This is just the right environment for our helical-bevel gear units with a torque range from 80 to 50,000 Nm.
With their high efficiency in both directions of rotation and at any input speed, these right-angle gear units are very energy-efficient. Their high-endurance gearing is wear-free and lasts a gear unit's lifetime. For precise positioning tasks, you can use the K series gear units with reduced backlash.
The particularly sturdy sizes K..39 and K..49 complete our range of two-stage helical-bevel gear units. They set the standards together with sizes K..19 and K..29: four sizes allow for torques from 80 Nm to 500 Nm.
Only half the solution without a motor? Then use our modular concept and combine the gear units of the K series with an AC motor to a K..DR.. helical-bevel gearmotor, or with a servomotor to a K..CMP helical-bevel servo gearmotor of your choice. Or simply choose the separate AC motor or servomotor that meets your requirements.
Your benefits
-
More cost efficiency
over the entire service life due to wear-free gearing and a long, maintenance-free operating life. -
High performance
in a compact design offered by 16 sizes with torque ratings between 80 Nm to 50,000 Nm. -
More energy efficiency
due to the high efficiency degree in both directions of rotation and at any input speed. -
Real lightweights
are the K..19 and K..29 sizes as their housing is made of aluminum.
