Nut holder
If the nut holder interferes or the
shaft slides heavily, adjust the
position and inclination of the nut
holder.
Assembly adjustment screw
Use a short wrench to adjust the position of the nut
holder. If you try to access from the vertical direction
with a straight wrench, you will not be able to adjust the
position and inclination of the nut holder because the
wrench interferes with the ball screw shaft and a load is
applied to the ball screw nut.

Assemble the shafts (Z1 and Z8) on both ends fully outside.
Temporarily fix the positions of the nut holders from the outer to inner shafts (Z1 to
Z4, Z8 to Z5), and adjust the positions starting from the inner shafts while adjusting
the ball screw nut assembly.
