Your benefits

Space saving
thanks to a more compact design than that of other gear unit types with the same power rating.

Reliability
thanks to gearing with infinite fatigue strength based on DIN 3990 (a design with finite fatigue strength is also possible).

Flexibility
thanks to the ability to freely combine the gear units with the DR.. modular motor system from SEW-EURODRIVE and the corresponding frequency inverters.

Speed
with short delivery times thanks to local assembly and optimized processes.

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.

The following table lists the nominal torque rated for endurance strength and the nominal torques taking into account the service life factor for the individual gear ratios.

fLC = (Lh x n2) / 1000

  • fLC = Service life factor
  • Lh = Required service life (h)
  • n2 = Speed at output shaft (min-1)
