K Series Helical-Bevel Gear Units


Thanks to their long maintenance-free operating life and their wear-free gearing, the helical-bevel gear units are – technically speaking – economical right-angle gear units. Their high level of efficiency, however, makes them real energy savers.


The compact design of all the gear units is most obvious in the 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 the 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 the 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.
