KP1-MDC single-axis modular drive unit with counterbearing

The KP1-MDC single-axis modular unit consists of a drive and counterbearing with a hollow shaft. It enables simple and flexible implementation of customer-specific solutions and is available with a payload capacity of 250, 500, 750, 1,000, 2,000 or 4,000 kilograms. 

Advantages of the KP1-MDC single-axis drive unit:

  • Simple planning: 
    The KP1-MDC makes planning even easier – with its identical loading height and the same hole pattern up to 1,000 kg.
  • Modular design: 
    The modular structure of the positioners provides maximum flexibility for implementing individual customer solutions. 
  • Space-saving construction:
    The KP1-MDC single-axis positioners are modular, highly compact units and are even suitable for confined installations.
  • Infinite rotation: 
    Thanks to its infinitely rotating design, the KP1-MDC single-axis positioner is optimally positioned and can be used without limitation in any axis orientation.
  • Any installation position: 
    Deploy the KP1-MDC in floor, wall, angle or ceiling-mounted positions without any restriction on the function or precision.
  • Integrated hollow shaft: 
    There is a hollow shaft integrated into the counterbearing. In the KP1-MDC HW variant, the drive unit also has an integrated hollow shaft. This allows energy and fluids to be supplied in a particularly space-efficient and favorable manner.
  • Simple integration: 
    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%.
