  1. Slide the nut housing over the ballscrew and tighten it with 8 screws.
    1. On the threaded side of the ballscrew, install the bearing support FK12 with the flat surface facing the tip of the screw.
      1. Tighten the counter nut on the FK12 bearing block, and don't forget to also tighten the small side screws.
        1. Install the coupler and firmly tighten it on the shaft of the ballscrew.
          1. On the other side of the ballscrew, slide the bearing support FF12.
            1. Repeat these steps to have twice the same assembly.
