Drive Units


  • AOK and AGK drive units are ready-to-install drive axes with ball screw assemblies; nut housings, and pillow block units
  • They are available in three sizes with freely configurable lengths up to 5600 mm
  • In conjunction with the Rexroth rail systems, you are given all the design freedom you need to build a machine
  • High positioning accuracy and repeatability thanks to the ball screw assembly with backlash-free, pre-tensioned nut system
  • Variable lengths and versions thanks to configuration with numerous options

AOK and AGK Drive Units consist of Rexroth's proven Ball Screw Assembly (BASA - BAll Screw Assembly), which with Nut Housings and Pillow Block Units make it into a ready-to-install drive axis. When combined with an external linear guide, this Drive Unit becomes a fully functional linear axis for a variety of applications.

  • AOK Drive Units in open format are ready-to-install drive axes consisting of a ball screw drive with nuts and pillow blocks, as well as an optional Nut Housing
  • Three coordinated sizes in any length up to Lmax.
  • A version with fixed and floating bearing or also with only fixed bearing is available
  • Driven by precision ball screw assembly in rolled design in accordance with DIN 69051: Screw available in tolerance grade T5 or T7, different nut versions to select from depending on the size and lead, three different preloads to select from (C1, C2, and C3)
  • Pillow blocks available in aluminum or steel design
  • AGK closed-type drive units are ready-to-install drive axes consisting of ball screw assemblies, nut housings, and pillow blocks, as well as an aluminum protective profile with cover strip as an enclosure
  • Three coordinated sizes in any length up to Lmax.
  • The Rexroth Ball Screw Assembly is optimally protected by the protective profile with steel or polyurethane sealing strip
  • Driven by backlash-free, pre-tensioned ball screw assembly in rolled design in accordance with DIN 69051 in the tolerance grade T5 or T7:
  • High traversing speeds thanks to large leads with simultaneously high precision over long lengths
