KP1-HC single-axis positioner with counterbearing

The KP1-HC single-axis positioner with horizontal rotational axis consists of a drive and counterbearing with a hollow shaft. It is available with a payload capacity of 250, 500, 750, 1,000, 2,000 or 4,000 kilograms. Tool radii of 950 to 1,250 millimeters offer maximum possible flexibility in system design.

Advantages of the KP1-HC single-axis positioner:

  • Broad portfolio:
    Thanks to the wide range of tool radii, loading heights and payload capacities that are available, you can enjoy the greatest possible flexibility when designing your system.
  • Integrated hollow shaft:
    The hollow shaft integrated into the counterbearing can be used to route the energy and fluid supply lines in a highly space-efficient and convenient manner.
  • Infinite rotation:
    Thanks to its infinitely rotating design, the KP1-HC is optimally positioned and can be used without limitation in any axis orientation.
  • Low space requirements:
    Thanks to its compact design, the KP1-HC single-axis positioner can be easily integrated anywhere. Enjoy greater creative freedom in the planning process.
  • Simple integration:
    The optional connecting tube of the KP1-HC allows you to align the drive and counterbearing easily and accurately.
  • Flexible alignment:
    The length compensation of +/- 5 mm integrated into the counterbearing enables compensation of tool carrier tolerances. 
  • High welding power:
    Weld with up to 1000 A with a duty cycle of 100%.
