Your benefits

Save on installation space
through the short and compact mounting position of the industrial planetary gear units.

Reduce weight
by having a lightweight gear unit design.

Gain flexibility
thanks to the free combination with SEW-EURODRIVE gearmotors.

Shortest delivery times
thanks to the "to go program".

Perfect for all heavy-duty applications

The load is distributed across multiple planet gears, resulting in a significantly higher power density and thus enabling smaller dimensions compared to other gear unit types. The PKK series planetary gear units are therefore perfect for all heavy-duty applications that require a robust, compact design and high gear ratios.

In addition to gear unit design such as flange and foot mounting, the variance at the input and output offers great flexibility for the user. On the output end, a solid shaft with key and a splined solid shaft are available. As a hollow shaft gear unit, you can choose between a splined hollow shaft and a hollow shaft with shrink disk. On the input gear end, the motor connection is made either via an exposed shaft-end or a motor adapter. Access to the complete modular motor system from SEW-EURODRIVE with extensive options such as brakes and encoders also offer further degrees of freedom.
